Albidur EP 5340 Silicon modified epoxy resin Hanse Chemie Impact Modifiers ADHESIVE Additive for impact modification and surface improvement dispersed silicone elastomer-modified reaction epoxy resin with a previously unattainable combination of advantageous material properties. The available resin bases are epoxy resins (EP), polyols (PU), unsaturated and vinyl esters, whose beneficial properties are almost perfectly combined with those of silicone elastomer. Used in construction adhesives. Improved toughness of the cured resin as compared with the respective base resin, with virtually unchanged heat resistance The accustomed advantageous characteristics of the cured base resin remain largely unchanged, in particular hardness, temperature resistance, chemical resistance, age and weather resistance as well as glass transition temperature Effectiveness of modification even at low temperatures Improved surface characteristics Improved electrical characteristics, especially at high temperatures Improved workability ALBIDUR resins are two-phase crosslinkable resins, generally fluid, that polymerise to the desired cured resin with a suitable curing agent. The impact mechanism is due to the fact that the elastomer plastic component built into the resin, the silicone elastomer, is in a different phase as a very fine particulate. As already mentioned, the silicone particles are surrounded by a graft shell that is compatible with the respective base resin and thus makes the entire system stable. After curing, the reactive groups of the graft shell result in a firm, insoluble bond of the resin to the elastomer particles. This kind of impact resistance improvement is entirely different from the single-phase modifications used in some reaction resins. the crosslinking density of the cured resin is reduced. While this reduces its brittleness, it also negatively influences desirable characteristics such as temperature resistance, elasticity module, flexural strength, compressive strength, chemical resistance, heat resistance and elastic properties. Dispersed silicone elastomer-modified reaction epoxy resin. Used as an additive for impact modification and surface improvement in construction adhesives. Improves toughness of the cured resin, surface and electrical characteristics and workability. Base resin: cycloaliphatic.
