Zero-Shrink polyester cures at room temperature. (Composites).Reactive Solutions, Inc., Elburn, Ill., claims to have achieved a breakthrough with a zero-shrink polyester resin Polyester Resin - Unsaturated Polyester Resin. The term generally used for unsaturated (means containing chemical double bonds) resins formed by the reaction of dibasic organic acids and polyhydric alcohols, basic component of SMC/BMC. that cures at room temperature with standard MEKP MEKP Methyl Ethyl Ketone Peroxide , needs no filler, and produces a Class A finish. New Plus 1 resin is one-component (including thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. low-shrink additive), pre-promoted, and thixotropic. It is designed for spray-up and hand lay-up of automotive, truck, RV, medical, and marine parts and tooling. Dimensions and surface quality are said to be unaffected by repeated laminations or a paint-bake cycle. Plus 1 is a clear liquid that allows visual confirmation of wet-out before it cures to a creamy white. It contains 50% styrene sty·rene n. A colorless oily liquid from which polystyrenes, plastics, and synthetic rubber are produced. Also called vinylbenzene. , giving a room-temperature viscosity of 50 to 750 cp. With 1.5% MEKP 9 (Norac), gel time is 17 min, and peak exotherm of 400 F occurs in 21 min Tel: (630) 365-0269 |
