CASS Polymers (Madison Hts., Mich., U.S.A.) has introduced ProBuild Epoxy Laminating Systems, designed to be convenient, easy-to-use epoxy systems for fabrication, restoration or repair of composite components. The product's versatile hardener selections and convenient 3:1 volumetric mix ratio allow for ease-of-use, regardless of project size, says the company. A choice of four hardeners provides working life from 16 to 90 minutes. The hardeners can be blended to produce the work life needed for a specific application. The laminating systems are 100 percent solids, formulated with UV stabilizers, and their unique chemistry reportedly minimizes blush.
