SYNTEVEN 440
unsaturated polyester filler/putty resinSYNTEVEN 440 is an unsaturated styrene polyester resin modified with DCPD, pre-accelerated with amine, very reactive, and highly stabilized. SYNTEVEN 440 is used as a single binder for the formulation of fillers for the treatment of metals, wood, and mineral substrates. SYNTEVEN 440, after the addition of benzoyl peroxide, hardens cold even at very low temperatures, giving rise to a polymer of medium hardness. The fillers formulated with SYNTEVEN 440 harden completely at both high and low thickness and are particularly suitable for the automotive sector. We recommend the use of appropriate fillers such as talc, dolomite / calcite, crystalline gypsum, and iron-free barites. Talc, considering its property of improving the characteristics of sandability and adhesion to the substrate, should represent the main component. In addition, fillers with a greater spherical shape such as dolomite, gypsum, and barite, results in the product being more compact.
