KAPGUARD® with Kynar® is a factory-applied, high-performance protective coating for composite exterior building products.

This architectural coating is formulated with Kynar® PVDF resin, a tough thermoplastic polymer resin that helps provide superior protection in harsh thermal, chemical and UV environments. KAPGUARD® offers bold and rich colors that don’t fade and degrade like traditional building products and paints.

KAPGUARD® incorporates a unique grade of Kynar® that can be cured at low bake temperatures and used on an unlimited number of material types, unlike traditional Kynar® coatings, which require 400° degrees Fahrenheit to cure, limiting their use to metal materials.

By incorporating complex inorganic pigments, KAPGUARD®  provides unprecedented color fastness, gloss retention, weatherability and a lifecycle of 20 years in the harshest environments.

Along with exceptional color retention, it is hydrophobic, resists mold and mildew growth, protects from stains and sheds dirt. When using infrared reflective (IR) pigment technology, KAPGUARD® can reduce heat absorption into the substrate. With low heat gain, the coating can reduce warping of the substrate and be cooler to the touch, a distinct advantage for composite decking and dark colored vinyl siding.

KAPGUARD® can be formulated in water or solvent and in one- or two-component chemistries. It is installed at the OEM and can be roll or spray-applied.
