Abstract

Optimality of choice of an antiadhesive for a specific molding surface when molding products from polymer composite materials (PCM) is determined by many factors: absence of scratching of coating from the surface of tooling and of transfer of release agent to molded blank, ease of removal and defectlessness of the product from PCM. Offers an additional factor for evaluating the optimality of selecting an antiadhesive for polymer tooling: determination of free surface energy (FSE), which gives a characteristic of tooling surface wettability. In the framework of this work the FSEs of five different antiadhesion compositions were investigated.
