EPIKURE™ Curing Agent P-201 and P-202

 

Product Description

EPIKURE Curing Agents P-201 and P-202 are phenolic hydroxyl terminated solid flaked curatives for functional and decorative epoxy powder coatings. EPIKURE Curing Agent P-202 contains 2-methylimidazole that functions as an accelerator to reduce the cure cycle. EPIKURE Curing Agent P-201 contains no accelerator.

 

Benefits

  • Both EPIKURE Curing Agents P-201 and P-202 are extremely clean. This is achieved by incorporating special process techniques that include filtration of the product.
  • The two curatives are packaged to minimize moisture pick-up.

1 The values are based on the mid-range of the equivalent weight specification for each epoxy resin and curing agent. In the case of the uncatalyzed EPIKURE Curing Agent P-201, a 100% stoichiometric reaction is assumed. With EPIKURE Curing Agent P-202, 80% of the stoichiometric level is recommended to compensate for epoxy homopolymerization that occurs in the presence of the contained catalyst.
