SHC 104-56/59 is a vapor barrier coating based on Chlorosulfonated Polyethylene (CSPE) rubber.
An ideal vapor barrier for low-temperature insulation including PIR and cellular glass.
A CSPE rubber elastomer — flexible yet resilient, with excellent flame resistance.
Excellent UV resistance preserves color; strong chemical resistance suits outdoor use.
