MEKP catalyst (methyl ethyl ketone peroxide) is a commonly used catalyst for the curing of unsaturated polyester and vinyl ester resins in composite manufacturing. It is a clear, colorless liquid that is highly reactive and can quickly initiate the curing process of these types of resins.
When MEKP catalyst is mixed with a resin, it triggers a chemical reaction that leads to the hardening or curing of the resin. This reaction is exothermic, meaning that it releases heat, which can accelerate the curing process and help to create a strong, durable composite part.
MEKP catalyst is typically added to the resin in small amounts, ranging from 1-3% by weight, depending on the specific resin formulation and curing requirements. It is important to use the correct amount of catalyst, as too little may result in incomplete curing and weak parts, while too much can cause the resin to cure too quickly and result in excessive heat generation, warping or cracking.
It is also important to handle MEKP catalyst with care, as it is a highly reactive substance that can be hazardous if not used properly. Proper personal protective equipment should be worn, and appropriate storage and handling procedures should be followed to ensure safe use.
