Resin 105 is the basic component of WEST SYSTEM products. It is a transparent, pale yellow, low viscosity liquid resin. When mixed with one of the WEST SYSTEM hardeners, it can be used to impregnate wood fibers, glass fibers and a variety of materials. It can harden over a wide range of temperatures to form a very tough solid with excellent moisture resistance.
There are several packages of resin base 105 that you can choose from when you are on the product sheet.
