STS Develops New Resin for Casting Socks
March 01, 2008
The STS Company has developed a new water curable polyurethane resin for its 17- and 30-in. tubular fiberglass casting socks. This creamier resin will maintain the softness of the fiberglass sock, allowing it to be more easily unrolled. The new resin more closely resembles the properties of plaster but without the side effects of prolonged setup and mess, while its shelf-life has been increased to 18 months. The cure time is 2-3 minutes, and the finished negative impressions will be more rigid than the previous version. Negative molds are an ideal alternative to fiberglass rolls or plaster bandages, and the positive molds require less finish work with greater accuracy.
