TruSeal Technologies: Solids Sealant System

March 15, 2004
TruSeal Technologies has released a product data sheet for EdgeTherm PIB-H1, a high-viscosity, high-strength, 100 percent solids sealant system. A polyisobutylene (PIB) sealant, PIB-H1 is the second rollout in the EdgeTherm line of IG sealants. EdgeTherm PIB-H1 is based on a PIB polymer formulated to impart reinforcement, resist degradation from ultraviolet light, and provide low moisture permeability. With its high viscosity formula, PIB-H1 resists shearing in large, heavy lites of glass, and retains flexibility through a wide temperature range to compensate for thermal movement of IG units. PIB-H1 is used as the primary seal on IG units while providing the main moisture vapor seal between the glass and metal spacer. It must be used with a secondary seal designed to provide structural strength. The product's properties provide a low moisture vapor transmission rate, consistent quality and excellent adhesion to glass and metal through a wide temperature range.
