What is phenolic resin?
Two types: "Novolak type" and "Resole type"! The reaction progresses and hardens by heating!
"Phenolic resin" is a type of resin that is mainly classified into two categories. The "Novolac type" is reacted with an acidic catalyst, and it is not reactive on its own. The reaction progresses when heated together with a hardener, leading to three-dimensional cross-linking and curing. On the other hand, the "Resole type" is reacted with an alkaline catalyst, and the reaction progresses upon heating, resulting in curing similar to Novolac. 【Features】 ■ Novolac type - Reacted with an acidic catalyst - The reaction progresses when heated with a hardener, leading to three-dimensional cross-linking and curing ■ Resole type - Reacted with an alkaline catalyst - The reaction progresses upon heating, leading to curing *For more details, please refer to the PDF document or feel free to contact us.
