EP3 Product Description

Master Bond Polymer Adhesive EP3 represents a breakthrough in epoxy adhesive technology featuring a hitherto unattainable balance of performance properties including both high shear and high cure speed. This one component adhesive system is formulated to cure at elevated temperatures, e.g., 5-10 minutes at 325-350°F, longer times at lower temperatures for maximum bond strengths. Tensile strengths in excess of 1800 psi are readily obtained after such short cure times. No mixing is necessary prior to use. Master Bond Polymer Adhesive EP3 produces truly exceptionally good performance bonds with durable high lap shear strength for service in the remarkably wide temperature range of below -100° to over 300°F. It offers superior resistance to impact, thermal shock, vibration and stress fatigue cracking while maintaining the moisture, creep, corrosion and thermal resistance typical of epoxy resin adhesives. It is 100% reactive and does not contain any diluents or solvents.

Master Bond Polymer Adhesive EP3 produces durable high strength, exceptionally tough bonds which are remarkable resistant to severe thermal cycling and many chemicals including water, oil, fuels and most organic solvents even upon prolonged exposures. Unlike many other epoxy adhesives, its performance is relatively insensitive to changes in cure schedules or substrate cleaning procedures. Adhesion to metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened adhesive is a superior thermal insulator. Color is gray. Master Bond Polymer Adhesive EP3 offers the convenience of a heat cure with no mixing prior to use and uniquely favorable bonding performance for even the most difficult applications in the aerospace, electronic electrical computer, metalworking, appliance, automotive and chemical industries.
