FluorAcryl 6298 glass, metal and plastic coatings
UV and heat curable hydrophobic, oleophobic and superhydrophobic coating products with exceptional abrasion, impact and chemical resistance

FluorAcryl™ 6298 is a poly-functional Perfluoropolyether (PFPE) acrylate and with exceptional hardness, toughness, chemical resistance, transparency, lubricity, hydrophobic and oleophobic properties. Films and coatings may be expected to provide long-lasting anti- fouling and easy cleaning from fingerprints and other contaminants on commercial and domestic surfaces. Compatible with many monomers, oligomers and solvents, the properties of 6298 can be modified to provide increased processability, hardness, abrasion resistance, elasticity and/or adhesion to metals, glass and plastics, including polyolefins. With or without pigments and other particulates, 6298 rapidly UV and heat cures in the presence or absence of oxygen.

Unlike mono and di functional fluorinated additives and oligomers, poly-functional 6298 will not mechanically weaken or reduce chemical resistance of the final polymer matrix, rather strengthening it and decreasing solvent penetration. While soluble in fluorinated solvents, the acrylate component makes 6298 soluble in many organic solvents, such as ethyl, butyl and isobutyl acetate, and clear, glossy coatings may be applied by dipping, spraying, spinning, roll coating, etc. The summary of data below illustrate the properties for 25 micron films on glass drawn from neat 6298 with 5% weight for weight MicroCure-46 photo initiator.

Surface Energy: ~ 15 dyne/cm2
Refractive index: 1.32
Contact angle to DI water: >105°
Roll off angle to DI water : ~8°
Contact angles to mineral oi: > 70°
Roll off angle to mineral oil: ~2°
Magic Marker resistance: beads up and easily removed
Pencil hardness: > 2H

Application Instructions:
1. Surface should be clean and free from oils and detergents.
2. FluorAcryl 6298 is provided in different solvents depending on the material being coated and the method of coating. It is important the all solvent is removed prior to UV curing. FluorAcryl can also be formulated as a low solvent material.
3. For most HVLP spraying, we recommend spraying a 10% concentration of FluorAcryl 6298, diluted with butyl-acetate (MEK or ethyl-acetate). Optimization of 6298 concentration in solvent is also dependent on spraying equipment and conditions as well as the thickness and properties desired for the coating.
4. Before UV-curing the FluorAcryl 6298 coating, it must be dried at the appropriate temperature long enough to completely evaporate all solvents, otherwise the coating will not cure.
5. After the solvent has evaporated, cure under 360-420 nm UV to a pencil hardness of greater than #2 using a 350 to 600 watt per inch UV. Coatings UV cured quickly at the above conditions provide the best hydrophobic performance (contact angle to water, 110-114° with ~5° roll off). Particularly good results can also be obtained when cured under UVC (
Ultraviolet C at 100–280 nm).

Health and Safety: The potential hazards associated with this product should be understood before use to ensure that they are used properly. Please review product’s MSDS before working with these materials. Most oligomers tend to have low skin and eye irritation, and skin absorption, ingestion and inhalation hazards are minimal because of their higher molecular weight compared to solvents and monomers. However, this product may be supplied as blends with monomers or solvents, and safety procedures guidelines of these additives may be applicable.
Fire: In the event of fire, this product, as with all fluorinated materials, can become an inhalation hazard or uncontrolled polymerization may occur. Fire fighters should wear self-contained breathing apparatus, in addition to eye, face and body protection. Extinguish fires with dry chemical, foam, carbon dioxide, or water fog and spray from a safe distance or protected location. Keep containers cool.
Handling and Storage: It is important to prevent exposure through the use of protective clothing and equipment, good work practices, and proper engineering controls. Do not handle this product in light containing UV, as it is highly reactive. Store containers at temperatures above 45°F and below 80°F. Recommended bulk storage temperatures should remain within the 45-80°F range. Material allowed to freeze should be heated to 100°F and mixed thoroughly with low shear to disperse inhibitors and other additives. Store out of direct light in non-transparent containers.
Shelf Life and Disposal: This product should be used within six months of receipt for optimum product performance. All safety guidelines should be followed. See 40 CFR 261 for further instructions on proper disposal. Disposal must comply with federal, state and local regulations.
Environmental: This product is not currently TSCA listed. Prior to commercial use a LVE will be established.
