Dear friends, today we will talk about the curing conditions of phenolic resin. The curing conditions are crucial for phenolic resin to transform from a liquid state into a strong material.

In terms of temperature, it generally needs to be in the range of 130 ℃ -170 ℃. If the temperature is not enough, the reaction will be slow and the curing will not be complete; Excessive temperature may also deteriorate the performance of the resin. Time also needs to be well controlled, usually ranging from a few hours, and adjusted according to the resin model and product thickness. In addition, catalysts are also essential, such as hydrochloric acid, oxalic acid, etc., which can accelerate the curing reaction. Only when temperature, time, and catalyst are perfectly combined can phenolic resin have good performance and show its talents in various fields!
