Epoxy resin
sr 1688
Product description:
SR 1688 is a syntactic epoxy casting resin specially formulated to produce lightweight parts while offering high compressive strength. With a Shore D hardness of ~75, low density, and excellent storage stability (no sedimentation), it is ideal for replacing conventional foams in demanding applications.
The SR 1688 / SD 4773 system can be cast from 20 °C, with the best quality achieved between 40 and 50 °C for precise detail reproduction and effective bubble degassing. Its 35% green carbon content makes it an environmentally friendly resin. Thanks to its balanced formulation, this resin is suitable for technical parts requiring high mechanical strength and long-term stability.
