SYNTEVEN 713 is an unsaturated high-solid polyester resin of the “direct glossy” reactive allylic type, that allows to obtain very hard films even at high thicknesses despite the absence of the monomer. It is used in the formulation of transparent and pigmented coatings for wood with conventional accelerator peroxide catalysis, characterized by ease of deaeration, absence of dripping even at high thicknesses. Furthermore, is used for the preparation of Top-Coat paints which must have a high solid content at the styrene-free during the applications fases.
