CORRO-DUR 257 is formulated for effective field application by brush, or roller at normal ambient temperatures. The CORRO-DUR 257 formulation is based on the unique CORRO-DUR 258 resin system which may be applied to damp or wet concrete surfaces and which has been flexibilized with an inert proprietary plastic . This resin system is toughened with Kevlar™* to give superior chip resistance and is pigmented with select hard ingredients to further enhance wear resistance.

 

The cured film is glossy with a slight texture resulting from the fiber reinforcement. Related products have been employed for underwater application and have been subjected to both radiation and DBA testing with excellent results. The resin system used has excellent resistance to commodities such as hydrocarbon oils and fuels, mineral acids and alkalis.

 

The solvent-free formulation avoids the objectionable odor and explosion hazards of epoxy solvent. Absence of solvent also assures compliance with all present and proposed air pollution regulations and prevents common service problems caused by shrinkage or water sensitivity of residual entrained solvent residues.
