Curox M200 MEKP Catalyst Hardener

MEKP Catalyst for Polyester Resin Curing and Fibreglass Lamination Systems

Curox M200 Catalyst is a high performance MEKP hardener designed for curing polyester and vinyl ester resin systems in fibreglass and composite applications. Available in sizes ranging from 125ml to 5kg, it provides reliable and consistent curing across both small repairs and large scale production work.

Formulated to deliver controlled reactivity, Curox M200 is commonly used where a slightly slower, more stable curing profile is required compared to standard MEKP catalysts. This makes it well suited to laminating processes where improved control over gel time and reduced risk of overheating are important.

The catalyst activates resin systems to form strong, durable laminates with excellent structural integrity. It is suitable for use in hand lay-up, spray-up and general composite manufacturing processes. Widely used across marine, automotive, construction and industrial sectors, Curox M200 is trusted for its consistency and performance.

Ideal for fibreglass fabrication, repairs and moulding work, this MEKP catalyst ensures dependable curing results when used according to recommended ratios.
