General Purpose resin for hand lay-up or spray-up applications
#78 General Purpose Laminating Resin is ideal for part fabrication and for building low cost molds. It is designed for robust processing and outstanding physical properties. #78 General Purpose Laminating Resin is ideal for operations that require low HAPS. As a first quality resin, the color, consistency, and properties of this resin will not vary from batch to batch. #78 General Purpose Laminating Resin is easy to work with and since it is wax free, you don't have to sand between coats.
As a wax-free resin, air must be inhibited during the cure cycle for repairs, single or thin layer applications. To inhibit air we recommend either adding #71 Styrene Wax to the resin, or spraying the applied resin with a coat of #13 PVA. If air isn't inhibited, the resin may not properly cure and remain tacky. For thick or multiple layer applications the heat generated during the exotherm will allow the resin to cure fully.
#78 Polyester resin is formulated for 1.25% MEKP catalyzation. This resin can be purchased alone or as part of a Resin and Hardener Kit.
