It reacts with resin to turn it from a liquid to a solid (cure it). It is used in varying ratios, generally between 1%-3%, depending on the product being used. Polymer Worlds MEK-P is made in the United States and comes with a measuring cup for easy usage. With its superior formula, it is perfect for all your industrial needs. MEK-P should only be used for Polyester based materials only. Mix for 45 to 60 seconds with resins before pouring.Use only if temperature is above 65 degrees for proper curing with resins gelcoats vinyl esters etc. Please use proper eye wear and breathing masks before using. MEK-P is flammable so keep away from any heat source when storing. This product is manufactured by the renowned brand Polymer World and is suitable for use in various industries including business and industrial settings. It comes in 8 ounces.

Review: It Works - Excellent Review: good price - good deal ## Features - ✅ Role of Catalyst: In composites, a catalyst is used to initiate and accelerate the curing or hardening of the resin system. MEKP is a free radical initiator that triggers the polymerization reaction in polyester and vinyl ester resins, leading to the formation of a solid and durable composite material. - ✅ Mixing with Resin: MEKP is typically mixed with the resin system just before application. The ratio of MEKP to resin is carefully controlled to achieve the desired curing characteristics and processing time. The specific ratio and mixing instructions may vary depending on the resin manufacturer's recommendations. - ✅ Curing Process: Once MEKP is mixed with the resin, a chemical reaction starts that causes the resin to crosslink and solidify. The curing process can be accelerated by applying heat, which helps to speed up the reaction and shorten the overall curing time. - ✅ Shelf Life: MEKP has a limited shelf life and can degrade over time, affecting its effectiveness as a catalyst. It is important to use fresh MEKP to ensure reliable curing performance. - ✅ Our Florida Based business has well over 7 years of experience in the boating industry, and we are just getting started.
