A clear, rigid, medium reactivity, medium viscosity and promoted fast curing unsaturated polyester casting resin. Reversol P-9140 resin is designed for use with calcium carbonate, aluminium trihydrate, silicates, quartz sand and other fillers commonly used in the manufacture of filledcasting or cultured marble products. Filler interaction with the resin affects the color of the product and can influence the gel time and cure rate. Surface properties are determined by the gelcoat. Gelcoat formulated for cultured marble applications is recommended. FEATURES Medium exotherm Low warpage Ideal for thick filled casting.
