Since its creation in 1894, BIP has moved on to become a world leader in the supply of thermoset plastics and chemicals with manufacturing and distributors now located worldwide. We were the first company to patent urea-formaldehyde resins during 1924, since which BIP has evolved into a technology innovator delivering class leading thermoset moulding materials, textile chemicals and paper chemicals.

BIP’s tradition of being first in emerging technologies continues currently with water-based polyurethanes, plastic blast media and biodiesel the environmental friendly fuel produced from recycled vegetable oils.

BIP manufacture a range of aqueous polyurethane dispersions for use in a wide variety of applic­ations. They consist of poly(urethane-urea) polymers that are dispersed in water. These disper­sions are environmentally friendly materials with no unreacted isocyanate groups and make a good choice for the formulation of compliant coatings for many different substrates.

The unique chemistry of polyurethanes means that it is possible to achieve large variations in properties by careful choice of the type and relative proportions of the monomers used. They are available in a variety of film hardness, can be readily blended with other water soluble polymers to optimise final film performance, application properties and cost.

Advantages

· Fast dry, ease of film formation · Excellent adhesion to various substrates · Low volatile organic content · Non-flammable solution · Outstanding flexibility and impact resistance · Excellent abrasion resistance · Compatible with other aqueous monomers and polymers · Flexibility, even at low temperatures · Excellent film formation · High Abrasion resistance · Toughness – high impact strength · Light stability · Excellent adhesion · Zero to low VOC · No free isocyante

A polyurethane dispersion is a liquid polymer which can form a continuous film via evaporation of water. Such products are generally used as surface coatings and textile treatments, but they can also be used as adhesives. The properties of the polymer can be changed by altering the ingredients - from very soft and tacky through to very hard and brittle. The softer products can often be used as adhesives (glue).

Choice of “Beetafin” PUD – Influence of the Isocyanates

Aliphatic Good hydrolytic stability

Aromatic Good toughness

Good u.v. resistance Higher cost

Poor u.v. stability Lower cost

A wide range of “Beetafin” PUD’s are produced from polyester based aliphatic isocyanates.

Formulating “Beetafin” Aqueous Polyurethane Dispersions

“Beetafin” aqueous polyurethane dispersions form films by a coalescence process. The discretely dispersed polymer parts are forced together into a continuous film as the water evaporates. Film formation can take place slowly at room temperature, but can be improved by the following:

• Decreasing the particle size of the dispersion • Increasing the temperature • Adding coalescing solvents • Decreasing film thickness • Lowering the glass transition temperature of the polymer

The addition of coalescing solvents also improve the film forming process and properties such as, clarity, water resistance and flow. To obtain good film properties PUD’s are generally formulated and examples of the types of additives are given below.

“Beetafin” PUD’s can be formulated together with other polymers which in most cases reduce the overall cost and can enhance properties such as hardness and adhesion. However some properties may be compromised. Typical blends include, acrylic emulsions, PVC for fire retardancy and alkyds which will improve hardness, chemical resistance and pigmentation.

The performance of “Beetafin” PUD’s can be further enhanced by cross linking. Examples of the typical properties which can be improved include:

• Water resistance • Heat resistance • Solvent resistance • Oil resistance • Grease resistance • Hardness • Better adhesion on some substrates.

Aqueous PU dispersions find use in a variety of applications that require high performance, the bonding of difficult substrates or the replacement of solvent-based systems. So why have PUD’s, (polyurethane dispersions) become so attractive?

· Firstly, there is a real requirement to produce compliant coatings (low VOC) which has fuelled the move to water based polymers. This is especially a requirement for export

· Secondly the performance of water based formulated PUD’s have improved in performance and are very effective and efficient coatings and adhesives even when used at low coating weights · Lastly, the need to tend to the future environment has resulted in major US and European importers to look at effluent produced and products used, right from the beginning so that they are not moving the pollution problem east.

Polyurethane Dispersion’s are used as coating, binding and adhesive products. There are so many applications it is impossible to note them all but binding, coating and adhesion is the basic job they are doing. Although we have products as indicated in the attached data we find that all applications even of the same actual type require slight variations to the PUD formulation. We complete these differences for individual customers by working together to obtain the performance they need from the PUD.

. It is therefore best to begin with an idea of what are you trying to obtain (which type of surface are you looking at, is it a coating an adhesive of a binder, is it a hard or soft film required, do you need added solvent etc.

In addition our Principals make as mentioned most of the products at 0 or a variety of solvent additions and this is only based on the end use needs and film forming ability.

Polyurethane dispersions for coatings have small particle size for flow and high gloss. Products have different elongation so that the resulting urethane coating can be matched to the substrate requirement for adhesion, resistance, gloss and weatherablity. Specialty coating applications include antigraffiti top coats, and glove coatings.

Polyurethane dispersions for adhesives and textile binders include anionic, cationic or nonionic dispersions, and are offered with a range of solids content, ionic charges, and adhesion, resistance and elongation characteristics to allow matching to specific application requirements. Applications include laminating adhesives, fiber sizes, and binders.

The main use for using water-based PUD in various applications would be where environmental legislation restricts or even prohibits the use of solvent-based equi­valents. However, in certain applications a water-based polyurethane dispersion may also offer a technical performance advantage in terms of resistance properties that is water, solvent and chemical resistance and possibly also wash resistance, certainly where the PUD would be cross linked.

It is not possible to keep stocks of these Products as the needs are different for different types of customers. Although we have products as indicated in the above mentioned data we find that all applications even of the same actual type require slight variations to the PUD formulation. We complete these differences for individual customers by working together to obtain the performance they need from the PUD.

GLASS FIBER SIZING

ROPE TREATMENT, THREAD and GLOVES coatings.

“Beetafin” polyurethane dispersions are made over a solids range of 30 – 60% with a wide range of film hardness and can be cross linked to enhance their chemical and water resistance. Low volatile organic content enables the production of compliant coatings.

Finally the particle size of the dispersion needs to be considered when coating. Fine particles help firm formation and provide better gloss. Larger particle size give better pick up in some dipping processes.

Storage Stability

“Beetafin” aqueous polymer dispersions will remain stable for 12 months from the date of dispatch if stored between 20 and 20oC. As with most aqueous dispersions they are susceptible to frost damage.

Material should be stored in tightly sealed containers and away fro direct sunlight as evaporation of water may cause deposits of PU film to form that will not be re-dispersible.
