Hardener for Epoxy resin
Polyaminoamide : Tohmide
"Tohmide" is the hardener for epoxy resin. It is a polyaminoamide compound with amide bonds and many amino groups in the molecule, which is synthesized from polymerized fatty acids and / or other carboxylic acids and polyamines. Among amine-based hardeners, it has an advantage in terms of safety and hygiene, and forms a cured product with excellent adhesiveness, toughness, and corrosion resistance. It is used for heavy-duty anticorrosion paints, lap joints for concretes, injection materials, adhesives, etc.
