Protective Coatings Made Better with
Kynar Aquatec® CRX Latex
Protect your high value assets from damaging ultraviolet radiation and weathering exposure. When other topcoats wither and fade, Kynar Aquatec® Resin-Based Coatings thrive in extreme environments.
A Superior Water-Based Protective Coating
Protective coatings formulated with Kynar Aquatec® PVDF latex, a fluoropolymer technology, resists dirt accumulation, mold and mildew growth and has exceptional longevity and weathering resistance due to the polymer’s unique chemical structure.
Kynar Aquatec®
