TYG-20 phenolic curing agent is a curing agent for epoxy powder coating produced by Xi’an Tianyuan Chemical Factory. The product is made of long carbon chain aliphatic carboxylic acid and phenolic resin to toughen and expand the chain, generating a polymer compound with both flexibility and rigidity, which is used as the curing agent for epoxy powder coatings.

When used as a curing agent for epoxy powder coatings, it has a similar structure to epoxy resins and is very compatible with them. When formulating epoxy powder coatings for heavy duty corrosion protection, the ratio between the hydroxyl value of the curing agent and the epoxy value of the epoxy resin is an important factor in ensuring the performance of the coating film. In order to speed up the curing reaction, it is necessary to add 2-methylimidazole and other alkaline catalyst, the amount of resin and curing agent total, which is about 0.5% of the total mass of the film-forming material is more appropriate.
