Cooley - Model C3 Plus PVC - High-Performance Commercial Roofing Membranes - Brochure

Developed in 1988 and commercialized in 1990, the original C3 formula (with Elvaloy) continues today to prove its reliability and durability. The C3 Plus product entered the market in 1994 with Cooley’s patented ultra-high-strength Aramid yarns added along the fastener edge to provide maximum tensile strength and puncture resistance where it counts the most. C3 is a proprietary formulation blending DuPont™ KEE (ketone ethylene ester) and PVC. This unique blend offers superior UV performance and the highest chemical resistance in a single-ply roofing product.
