EP41S-2 Product Description

Master Bond Polymer EP41S-2 is a two component epoxy resin compound designed for durable, high performance, tough, high strength adhesives, sealants, coatings and liners featuring outstanding resistance to fuels, alcohols and organic solvents. The EP41S-2 compound which is formulated to cure at ambient temperatures or more quickly at elevated temperatures, offers a degree of resistance to fuels and alcohols as well as many other active organic solvents unmatched by any other currently available epoxy resin composition. It can successfully withstand, for example, prolonged immersion in such strong organic solvents as gasoline, fuel oils, methyl alcohol, ethyl alcohol, toluene, ethyl and butyl acetates for more than one year in their films (5-8 mils) at both ambient and elevated temperatures without deterioration or weight changes making it a prime candi-date for automotive applications and likewise usage in the chemical process industries wherever long term resistance to fuels and high temperatures are prime requirements. Master Bond Polymer System EP41S-2 also features excellent resistance to inorganic acids, ammonia, sodium hy-droxide and many other chemicals.

Master Bond Polymer System EP41S-2 is 100% reactive, does not contain any solvents or diluents and cures with minimal shrinkage. It readily develops a high bonding strength of more than 2500 psi at room temperature to both metallic and many non-metallic substrates which unlike that of many other epoxy resin compounds, is relatively insensitive to mixing ratio and/or substrate cleaning procedures. Master Bond Polymer System EP41S-2 can be supplied if desired in a higher viscosity so that it can be applied without sagging or dripping even on vertical substrates. It produces exceptionally durable, high performance, tough, high strength coatings, liners and adhesive/sealants with outstanding resistance to organic solvents which are likewise remarkably resistant to thermal cycling over the wide temperature range of -60°F to >275°F. Adhesion to metals, glass, ceramics, cements, wood, vulcanized rubbers, and many plas-tics is excellent.

The Master Bond Polymer System EP41S-2 cures readily to produce an abrasion resistant, tough, strong, thermoset plastic with superior elec-trical insulation characteristics and a desirably low coefficient of thermal expansion. Color of part A black; part B amber. This versatile and cost effective epoxy compound is widely used in the construction, maintenance and repair, chemical process, metalworking, appliance and electrical/electronic industries where durable, high performance, tough coatings, liners and adhesive/sealants with outstanding resistance to organic solvents are required.
