Chemline Enters Cast Urethane Market

100% Solids, Cast Elastomer Systems from Chemline Offer Superior Cure and Performance Without Mercury

Press release date: October 14, 2016

St. Louis, MO – Chemline, Inc. offers highly effective, mercury-free cold cast elastomer systems for molds, rollers, liners and cast urethane parts. Since mercury catalysts have been rendered obsolete in the name of sustainability/environmental concerns, users of castable urethanes have had issues with the moisture sensitivity and physical property development of non-mercury formulations. Chemline cast resins don’t contain mercury, but can still cure in warm, humid conditions. This is especially important to manufacturers of large molded parts, where long open times render the urethane susceptible to reacting with moisture and long-to-demold conditions. Custom formulations are available for virtually any application.

Key features of Chemline’s cast elastomer systems include:
• 100% Solids, zero VOCs
• Isocyanates: MDI, TDI, HDI
• Resins: PTMEG, Polyester, Polyether
• Rapid de-mold times for open or closed mold casting
• Hand mix or machine applied
• Hardness available from Shore A 40 to Shore D 80
