Two-component elastomer offers the best of both worlds
Master Bond EP30D-12 is a versatile two-component elastomer featuring superior strength, toughness and unusually superior chemical resistance developed. EP30D-12 combines the advantageous performance characteristics of epoxy resins - such as adhesive strength and chemical resistance - with those of the polyurethane's - including toughness, abrasion-resistance and flexibility. The outcome is a product with high physical strength properties, such as a 7500psi tensile strength and a notable flexibility of 440 per cent elongation at break, combined with superior chemical resistance and durability as illustrated by its low water absorption, low moisture permeability and high hydrolytic stability.
EP30D-12 is easily processable in both thick and thin sections. Because of the low viscosity of the blended mixture, the compound flows easily and smoothly, even around intricate geometries. Parts more than 25mm (1inch) thick can be cast without undue exotherm development. EP30D-12 cures with minimal shrinkage in five to six hours at ambient temperatures to a tough elastomer with remarkably good resistance to thermal cycling and chemicals including water, inorganic salts, alkalis and acids, as well as many organic chemicals.
Adhesion to metals, glass, concrete, ceramics, wood, vulcanised rubbers and many plastics is excellent over the temperature range of -50 to +120degC (-60 to more than +250degF). EP30D-12 is recommended for high-performance bonding, sealing, casting, potting and encapsulation applications in the electronic, electrical, construction, metalworking, automotive and chemical process industries. It is available in premixed bi-packs and cartridge/gun packaging for convenient dispensing as well as in pint, quart, gallon and 5-gallon container kits.
