Innovative Products For The Infrastructure Repair Industry

Stephen's Technologies Newlife Liner Epoxy Lamination System

DESCRIPTION: A medium-viscosity, highly chemical-resistant, 2-part epoxy system formulated for the lamination of special fiberglass reinforcements designed by Stephen's Technologies, Inc. for the infrastructure repair

CHARACTERISTICS: Formulated with special additives and modifiers to enhance the water resistance, chemical resistance, bond strength to a variety of substrates, and internal strength. It is also has characteristics which provide for rapid wet-out of most types of reinforcing materials. It is designed to cure at temperatures as low as 40-deg. F.

APPLICATION: Designed for the lamination system patented by Stephen’s Technologies or for general hand lamination of felts, fiberglass, and other reinforcing materials.

ADVANTAGES: *Rapid Wet-Out Of Conventional Substrates* *Fast Cure To Allow Rapid Removal Of Carriers/Bladders* *Excellent Cure At Low Temperature And High Humidity* *Zero Induction Time* *0% VOC’s* *100% Solids* *Highly Water/Chemical Resistant * Long Working Time Relative To Cure Time* *Rapid Cure In Cold Temperatures* *DOT Non-Corrosive*

Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing and wash before re-wearing. Eye Contact: Flush immediately for 15 minutes with large volumes of water and seek immediate medical attention.

SAFETY AND HANDLING: This epoxy is typical of most epoxies in that the activator can cause skin and eye damage in the uncured state. Even the resin can cause some irritation upon prolonged or repeated exposure. Rubber gloves, protective eyewear, and protective clothing are strongly recommended when handling these materials. In the event of accidental contact, treat as follows:
