This product group, possessing high mechanical values and HDT, are widely consumed in automotive and construction industries. One of the main characteristics of RTM resins is the availability of providing smooth surfaces on both sides by closed mould system. Designed for transparent and filler type applications. Filler type reisn has very low shrinkage value and so widely consumed in thick casting applications.
