NORESTER® 2550NV is a polyester resin for the production of composite moulds with low shrinkage. It is a product ready to use, filled and pre accelerated.
Polymerise at room temperature following addition of MEKP (e.g. Butanox M50 from Akzo). Pre accelerated and promoted allowing a rapid production of moulds. Good surface appearance. Good curing. Good mouldability, and fast wet out, glass to resin ratio: 1 / 2. Lighter moulds with better mechanicals properties. Lower tooling resin costs due to prolongued mould life. Superior mechanical properties due to a glass content approximately 28% higher than with conventional tooling resin . Good dimentional stability. (long gel time)
