Substrate Materials

Polyester & Polycarbonate Film

Vistex 104-85-1 Anti-Fog Coating. when cured with heat, will render a surface permanently fog-free. Suitable for roll-to-roll coat appli-cation. Intended for use on poly-ester and polycarbonate film, Coating is ready to use with no solvent addition required. Vistex is a cross-linked hydrophilic polymer composition that causes condensed water droplets to spread evenly. Coating will not saturate and fail under very hu-mid conditions, as will many other anti-fog materials. Highly durable when wet, anti-fog prop-erties are retained even after repeated washing with commer-cial glass and lens cleaners.

Application & Cure Requirements Recommended dry coating thickness is 0.11 to 0.22 mils (3 to 6 µ). Thinner coatings will be less resistant to abrasion and may have reduced anti-fog properties. Theoretical cover-age ranges from 900 to 1800 sq. ft. per gallon (22 to 44 M2 per ltr). Baking should begin as quickly as possible after the coating application. Longer air dry times may prevent the coating from curing complete-ly, especially if the ambient humidity is above 70% RH. High humidity may also contribute to haze, notable at the top of coated parts. Proper curing is essential to the coatings per-formance. The use of temperature indicating labels is strongly recommended. A minimum surface temperature of 248°F (120°C) is neces-sary for proper curing to take place. Curing at 130°C is strongly recommended. Complete cure requires:

It is important to cure Vistex coatings at the highest temperature the substrate will with-stand. Coatings cured at lower temperatures will not be as hard as coatings cured at higher temperatures. Cure time depends on a number of factors, including the mass of the coated article and the efficiency of the oven. A yellow discoloration indicates the coating has been over-cured and exposure time should be reduced. Degree of cure can be evaluated by scrubbing 25 times with a fine (white) Scotch Brite® Pad and water at a force of approximately 250g/in². The coating should not smear or abrade form the surface. If more than a few scratches appear, the coating is either under-cured or it is too thin (less than 3 microns). These coatings usually have an iridescent (rainbow) appearance.

H E A LT H & S A F E T Y I N F O R M A T I O N Before using this product, read and understand the Safety Data , SDS, which provides information on health, physical, and environ-mental hazards, handling precau-tions and first aid recommenda-tions. For a copy of an SDS, con-tact an FSICT sales or customer service representative. HANDLING & SAFETY PRECAUTIONS Avoid contact with skin and eyes. Do not take internally. Observe proper industrial hygiene, includ-ing splash goggles and impervious gloves. Provide adequate ventila-tion. Avoid solution contact with strong acids or alkalis. Dispose of solution and clean-up wash water in accordance with local, state and federal regulations. Shipping regulations for flammable substance are applicable. Consult the SDS for further information, or call FSI Coating Technologies Inc. at 1-949-540-1140.

Substrates The preferred substrates are polyester or poly-carbonate film and sheet. Excellent wetting, flow and adhesion are usually obtained without the use of primers or additives. Plastics other than polycarbonate can be coated as long as the particular material can tolerate baking temperature of 266°F (130°C) or higher.

Maintenance & Care Properly cured Vistex coatings will usually out-last the coated item. Resistance to oil based stains is excellent. Water soluble stains may penetrate the coating if left in contact with it for an extended period of time. Grease and oils will contaminate the surface and impair anti-fog effectiveness. These contaminants can be removed with a strong grease cutting deter-gent such as Top Job®, Fantastik® or Formula 409®. Coated articles should be cleaned regu-larly to prevent accumulation of oily deposits. Avoid using abrasive cleaners or pads. It is normal for the coating to pass through a tacky phase as it dries. To clean, wipe with wet cloth or paper towel and allow to dry. Do not try to rub to dryness. This will leave smudges and will necessitate cleaning again.

Scratch Resistance The scratch resistance of Vistex is superior to untreated polycarbonate; however it is not designed to perform like silicone or acrylic hard coats. Superficial scratches caused by finger-nails, harsh fabrics or other abrasive materials, such as Velcro, can be permanently healed by wiping with a damp cloth or by breathing on the scratched coated surface. The coating will not crack, peel or flake as it ages.

5 to 15 min. 266°F (130°C)

1 to 2 min. 302°F (150°C)

Chemical Resistance Vistex coatings are unaffected by brief expo-sure to: Methanol, ethanol, isopropanol, ace-tone, methyl ethyl ketone, diacetone alcohol, toluene, hexane, gasoline, glycol esters, ethyl acetate, & ammonium hydroxide solution.

Avoid exposure to strong acids and alkalis. Alcohols will soften the coating and make it more susceptible to gouging by hard objects. After drying, normal hardness will return.

Shelf-Life Vistex solutions will remain usable for six months or longer if stored at 77°F (25°C). A light, fluffy precipitate may develop on stand-ing, and this can produce slight haze or particu-late contamination in cured coatings. Usually this does not become apparent for several months at least. If it does appear, precipitate should be re-dissolved by warming briefly to about 150°F (65°C).

Test old solutions before use. Any mixture that has become milky or contains white insoluble precipitate must be discarded.

Clean-Up & Removal Equipment is best cleaned with soap and water or a water and isopropanol solution. Removal of dried coatings may require a strong polar solvent such as N-methyl pyrrolidone or diace-tone alcohol. When fully cured, it may be im-possible to remove the coating except by me-chanical abrasion.

Suggested Tests for Vistex Materials Degree of Cure: Pencil hardness when wet should be 5B or greater. Cure can be evaluated by scrubbing with a white Scotch Brite pad (3M Co.) and water. After 25 rubs, the coating may be scratched considerably, but should not be abraded from the substrate. If the coating turns milky or smears when rubbed with a wet cloth, it is grossly under cured or has been improperly formulated.

Suggested Tests for Vistex Materials (Cont.) Coatings that are less them 3 microns (0.12 mils) thick will have less resistance to abrasion and may seem to be under cured. Such coatings usually have an iridescent (rainbow) appearance in reflected light. Anti-Fog Test#1: The test surface is immersed in distilled or deionized water for 1 hr. and allowed to dry for at least 1 hour. It is then placed face down over a container of warm water (122°F/50°C) so as to completely cover the opening. Vistex coatings may exhibit a ring of condensation as the coating hydrates, but will remain clear indefinitely thereafter. When sufficient moisture has condensed to form large water drops, the test is complete. Anti-Fog Test#2: The test surface is immersed in distilled or de ionized water for at least 24 hours, removed and allowed to dry at least 1 hour. The sample is then cooled in a refrigera-tor to approximately 70°F (4°C) and 70% to 80% relative humidity. Materials coated with Vistex will remain free of fog indefinitely. Untreated plastics or glass will fog in a few seconds. Inferior anti-fog coatings may fog immediately, or remain clear for a short time until they become saturated. Durability; Scratch resistance is superior to most untreated plastics. Superficial scratches in the coating that do appear when it’s dry will heal themselves when moistened in water or by breathing on the surface. The following data were obtained using a white Scotch Brite Abrasive Pad at 500 gr. per cm as measured by a UV spectrophotometer.
