PC-280
Two Component, Solvent Free
Elastomeric Base Membrane

Product Description
PC-280 is a two component, very rapid setting, rapid curing, Technical Data (Based on Draw Down Film)
solvent free, flexible, high performance, and high solids
polyurethane elastomeric coating that can be applied to Coverage Rate 1 gal/100 sqft
suitably prepared interior or exterior concrete, plywood and 0.41 l/sqm
metal surfaces. Due to very rapid gel time, PC-280 is suitable
for applications in temperatures as low as 20°F (-6°C). It may
be applied in a single or multiple applications. PC-280 is also Dry Film Thickness per 15 ± 1 mils
relatively insensitive to moisture and temperature allowing Coat 381 ± 25 microns
applications in varied temperatures and humidity.
