Heat resistant

epoxy system sicomin sr1710 sd7820, epoxy resin for tooling, high temperature epoxy resin (Set of 2 components resin + hardener)   High temperature epoxy system SR1710 / SD7820 Each kilo includes 0.73 kg resin + 0.27 kg hardener High temperature epoxy system specially formulated for oven temperature or autoclave conditions curing. It is used for production of high performance and high temperature resistant parts with outstanding mechanical properties in sectors such as motorsport, aerospace, and many more. It is also used for manufacturing of temperature resistant molds. It has low viscosity allowing fast wetting of reinforcements, and exhibits excellent adhesion properties to all types of fibers. It is very handy for most demanding applications, with a very long working time (~ 8 hours at 20° C/ 68 oF). It can also be used to step up production to higher temperature resistance, as it can be demolded after a relatively low temperature postcuring. Heat treating to resist higher temperatures may very well come as a second step or at a later time. For this reason this system is very useful when we have to work with plugs or molds that do not resist high temperatures. The initial minimum curing before demolding is 12 hrs at 40° C/ 104 oF or 6 hrs at 60° C/ 140 oF.
