PRODUCT DESCRIPTION

Epoxy Coal Tar Pitch Thick Paste Coating for Winter is based on epoxy resin and coal tar pitch, ultra-fine pigment, filler and new additive, with isocyanate as curing agent. This product contains two parts: part A is the main paint and part B is the curing agent, among which the part B can be used for both primer and finish. This two-component epoxy coating can be cured at low temperature with construction temperature ranging from -10℃ to 36℃. The paint’s firm film is resistant to abrasion, sea water, and crude oil.

Typical Uses:

This product is able to provide long-term protection to steel in severe corrosive environment such as the bottom of ships and boats, crude oil tanks, ballast tanks and the outer side of various buried steel pipelines in the cold areas.
