MAINCOTE™ AU-28 Waterborne Acrylic Polyol for Two-Component Waterborne Polyurethane Coatings

Description

Maincote AU-28 waterborne acrylic polyol is a hydroxyl-functional polymer useful in high performance and low VOC industrial coatings. It can be crosslinked with water-dispersible polyisocyanates in two-component waterborne polyurethane coatings, and with aminoplast resins such as melamine-formaldehyde resins in one-component baking systems. Maincote AU-28 provides clear and pigmented topcoats with high gloss and excellent durability for industrial maintenance and general industrial finishing applications. These coatings have an excellent balance of aesthetic appearance and durability, hardness, chemical and solvent resistance, corrosion resistance and pot life. Coatings based on Maincote AU-28 also have low VOC levels (< 100 g/L), and offer environmentally friendly alternatives to solventborne two-component polyurethane coatings.

Maincote AU-28, as supplied, has the low toxicity profile typical of acrylic latex polymers. Users are urged to consult the Material Safety Data Sheets supplied with all ingredients of a coating, and to heed the handling recommendations therein. Note: Two-component waterborne formulations containing polyisocyanates can generate dangerous overpressures of carbon dioxide in closed containers. Please exercise caution when working with these materials.

Potential Applications

• Industrial Maintenance Finishes e.g., steel and concrete structures, bridges, storage tanks • Transportation Finishes e.g., railcars, shipping containers, agricultural equipment • General Industrial Finishing e.g., agricultural and construction equipment • Flooring e.g., pigmented coatings for concrete floors

Performance Data

Table 1 shows the film properties of two-component Maincote AU-28/polyisocyanate coatings (formulations G-28-1 and G-28-2) versus conventional and high solids solventborne polyurethanes in gloss white formulations. Formulation G-28-1 was developed for general-purpose industrial maintenance applications. Formulation G-28-2, which uses a combinations of a higher isocyanate level and fast-evaporating coalescent, was designed for applications where faster hardness development is required. These two formulations serve to illustrate the range of performance that can be obtained with proper formulation of Maincote AU-28. Key results of this comparative study are:

• Systems based on Maincote AU-28 have much lower VOC than solventborne controls. • Coatings based on Maincote AU-28 perform comparably to the solventborne controls in gloss, durability, solvent resistance, hardness and abrasion resistance. • Coatings based on Maincote AU-28 have better flexibility than the solventborne controls at equal hardness. • Formulation G-28-2 gives rapid hardness development, suitable for general industrial finishing applications. • All of the coatings gave excellent salt spray resistance when tested over a high-quality primer/midcoat system.

Poor early water resistance is a shortcoming often associated with water-soluble curing agents for two-pack finishes. Exposure of a fresh coating to mist or light rain can be simulated by exposure in a "fog box" after a short dry time. When tested under these conditions, a Maincote AU-28/ polyisocyanate coating actually outperformed a solventborne urethane control, which suffered a dramatic drop in gloss (Table 2).

Pot life of these coatings is in the 4-6 hour range. There is not a definitive endpoint as evidenced by gelation, but most formulations show some viscosity increase 6 hours after mixing. Results for formulation G-28-1 are shown in Table 3. Performance properties generally do not drop off catastrophically after this time, although there may be some loss in gloss. Pot life is best judged in the context of the specific application and its critical property requirements. For formulation G-28-1, the viscosity remains fairly constant after isocyanate addition and until late in the pot life, when it increases somewhat. The stability of the viscosity during the pot life is very dependent on the formulation. The type and amount of neutralizer, the level of pigment dispersant, the type of coalescent, and the isocyanate level all have important effects, and other ingredients can be expected to as well. Formulations should be checked for their effect on viscosity stability as well as other key properties. The variables cited can be used to manipulate stability. Paints based on this resin will thicken considerably over the course of several days, but may not gel. The isocyanate is fully reacted at this time however, and the formulations are not usable.

The choice of polyisocyanate can play a large role in the final appearance and performance of the two-component polyurethane coating. There are a number of water-dispersible polyisocyanates available. The bulk of the work with Maincote AU-28 has been done with Bayhydur 302, which is found to disperse easily and provides good gloss and film properties. An alternate polyisocyanate which also provides acceptable performance is Rhodocoat X EZ-D 401. A comparison of the two polyisocyanates in a gloss white formulation based on Maincote AU-28 (G-28-5, for Bayhydur 302 as shown below) is given in Table 4. The Rhodocoat X EZ-D 401 provided slightly better hardness, but in general, properties were very similar for the two crosslinkers. The same comparison is given in Table 5 for a gloss black formulation (G-28-6). In the black formulation, the Rhodocoat X EZ-D 401 showed a slight advantage in gloss retention in accelerated weathering.

Maincote AU-28 can be used in both field-applied industrial maintenance coatings, as well as in factory-applied general industrial finishing. An example of a coating suitable for applications such as high gloss equipment finishes is the gloss green formulation G-28-7. Performance of G-28-7 is described in Table 6. The formulation is observed to have good gloss, durability, chemical resistance, hardness and flexibility. Use over a good primer, such as a waterborne primer based on Avanse™ MV-100, provides a waterborne coating system with excellent corrosion resistance. The primer/topcoat system showed no failure after 500 hrs salt spray (ASTM B117) when applied at a total of 4 mil dry film thickness over Bonderite 1000 cold rolled steel.

Formulating Guidelines

In addition to the resin, the other ingredients in a coating formulation and/or their level of usage can play a significant role in the performance of the coating. The choice of ingredients can impact the protective, aesthetic and application properties of a coating, and thus should be evaluated carefully. The following guidelines serve as a starting point to help in maximizing the performance of coatings based on Maincote AU-28 resin. Formulations should be fully tested prior to commercialization.

Coalescents

Coalescent selection can be used to manipulate performance. Hydroxyl-functional coalescents like Texanol, Dowanol PPh or Dowanol PnB do not appear to hurt performance, although they are capable of reacting with the isocyanate. These polymer-soluble coalescents are more effective at reducing minimum film formation temperature than water-miscible coalescents like N-methyl pyrrolidone or Butyl Cellosolve. A suitable coalescent without hydroxyl-functionality is Proglyde DMM (dipropylene glycol dimethyl ether). A starting point formula using Proglyde DMM is given in G-28-5. Fast-evaporating coalescents, such as Dowanol PnB and Proglyde DMM, also give faster hardness development and are useful alone or in conjunction with higher isocyanate levels in applications requiring such performance.

Pigments and Colorants

Choice of TiO2 type is important in controlling gloss and durability. Ti-Pure R-706 gives excellent results. Ti-Pure R-960 gives somewhat lower but still acceptable gloss. The effect of PVC on gloss with Ti-Pure R-706 is shown in Table 7 form formulation G-28-1. Excellent gloss is obtained even at 21% PVC, unlike typical waterborne systems, which generally show a drop in gloss as PVC is raised.

A highly durable grade of titanium dioxide, such as Ti-Pure R-706 or Tiona RCL-696, is recommended for the best durability in topcoats. Coatings based on Maincote AU-28 can also be formulated with other inorganic and organic pigments. Formulations for a gloss red (Formulation G-28-4) and gloss black (Formulation G-28-3) based on dry pigments are included in this brochure.

Care should be taken when selecting pre-dispersed colorants, as many contain surfactants and glycols which can affect final film properties. Suitable pre-dispersed colorants include the UCD E-line, industrial colorants based on dispersing resin and which do not contain glycols. Examples of formulations using pre-dispersed colorants include the gloss black (G-28-6) and gloss green starting point formulation (G-28-7) included in this brochure.

Polyisocyanate

A water-dispersible polyisocyanate should be used as the crosslinker with Maincote AU-28 in two-component waterborne polyurethane formulations. Most of the work described in this bulletin has been done with Bayhydur 302. Other suitable polyisocyanates include Rhodocoat X EZ-D 401. Both materials appear to disperse well and provide coatings with good gloss and film properties. Formulations based on Maincote AU-28 should typically contain an excess ratio of isocyanate to hydroxyl, because the reaction of the polyisocyanate with water will use some of the available isocyanate functionality. A typical ratio that has given good results is 2:1 NCO/OH on an equivalents basis. The level of polyisocyanate can also be adjusted to modify film properties such as hardness. NOTE: The reaction of polyisocyanate with water generates carbon dioxide. Containers of mixed two-component waterborne formulations containing polyisocyanate should never be sealed tightly, as dangerous pressure may build in the can. Always exercise caution when working with these materials.

Mar aids Mar resistance can be improved dramatically by inclusion of a mar aid. Suitable mar aids include Byk 333, Byk 337, and TegoGlide 410 at levels of approximately 0.3 – 0.5% on total formulation weight.

Defoamers Foam control is a major concern in waterborne paint formulation design. Additives are necessary to eliminate foam during manufacture and film application. The choice of defoamer type and level will depend primarily on the formulation and mode of application. Effectiveness of the defoamer can be screened by the shaker test, but the best candidates should be checked by actual application. Drawdowns should be made to check for surface defects and impact on gloss. Defoamer persistence should be checked by oven aging and retesting the defoaming capabilities. Suitable defoamers for Maincote AU-28 include Tego Foamex 800 and 825.

Rheology Modifier and Thickenersb HEUR-type (hydrophobically-modified, ethoxylated urethane) associative thickeners, such as Acrysol RM-8W, Acrysol RM-8, Acrysol RM-825, or Acrysol RM-5000 are recommended. Anionic rheology modifiers and cellulosic thickeners should be avoided.

Maincote AU-28 can be used as supplied (pH 7.0 – 8.0) or further neutralized with ammonia or organic amines such as triethylamine. Neutralization of the resin to pH 8.5 gives better resistance to soft-settling. Neutralizer type and level will also affect heat-age stability of the Part A formulation and viscosity stability after isocyanate addition.
