United Coatings Kymax Coating


United Coatings Kymax Coating is an innovative technology based on Kynar® Aquatec PVDF fluoropolymer resin, designed to deliver the proven durability and performance of traditional Kynar® PVDF coatings. However, rather than requiring high temperature baking, it is an air-dry finish that cures at ambient temperatures.

United Coatings Kymax Coating is a low-build elastomeric finish coating that provides the ultimate in reflectivity, color stability, algae resistance, and weatherability over new or existing roof surfaces. Although it is highly flexible, it exhibits a tough, enamel-like finish that resists abrasion, resistance to biological growth, dirt, acid rain, and all types of weather extremes.

Sizes Available:

1 quart
1 gallon (3.8 liter) can
5 gallon (19 liter) pail
54 gallon (208 liter) drum
275 gallon drum

Colors Available:

White, Custom colors


  • High Reflectivity/Emissivity – United Coatings Kymax Coating is listed with the Cool Roof Rating Council with an SRI (Solar Reflectance Index) of 110, which is among the highest of any roof coating.
  • Reduced Energy Costs – United Coatings Kymax Coating has the ability to repel dirt, biological growth, pollution fallout, and other contaminants, as well as resist degradation from UV and weather exposure. This enables the white topcoat to effectively reflect the sun’s heat over long-term exposure, unlike dark-colored roofing materials that retain heat and are subject to ultraviolet degradation. Roof temperatures can be reduced, significantly reducing air conditioning loads and lowering electricity costs.
  • Microbiological Resistance – United Coatings Kymax Coating was independently tested for fungal resistance as per ASTM G21-96. After exposure for 4 weeks at 28°C, its test panels showed no growth.
  • Color and Gloss Stability – United Coatings Kymax Coating is manufactured using Kynar® Aquatec resin, which is based on proven Kynar 500® technology. This fluoropolymer is universally known as the world’s most weatherable coating resin, and is resistant to UV degradation. The mixed metal oxide pigments used for tinting this product provide ultimate color stability and gloss retention and are able to provide relatively high reflectivity values even in darker colors.
  • Code Approvals – United Coatings Kymax Coating is UL classified as a Class “A” Fluid Applied Coating System, as outlined in the UL Roofing Materials & Systems Directory and UL website. It is also certified to meet ENERGY STAR®, Cool Roof Rating Council (CRRC), LEED®, and California Title 24 reflectance and emissivity criteria.


  • Was designed for application as a thin-build finish coat over liquid-applied roof systems and roof coatings.
  • Can also be applied directly over approved substrates such as metal or specific single-ply membranes to rejuvenate color and/or increase reflectivity, dirt pick-up resistance, and algae/mildew resistance.
  • Is recommended whenever exceptional weatherability and/or reflectivity are required, whether the threat is algae, mildew, dirt, or industrial fallout. It also provides exceptional UV and color stability, even in bright colors.
  • Is an excellent barrier to plasticizer migration, and is also effective in preventing asphalt bleed-through.
