Water clear casting epoxy system SR Green Cast 160 / SD7160
Each kilo includes 0.70 kg resin + 0.30 kg hardener
Water clear, low odor epoxy system, designed for decorative parts and jewelry prototyping, where a high transparency finish is required.
SR Green Cast 160 / SD7160 system:
The SR Green Cast 160 / SD7160 system exhibits very slow reactivity that allows casting of thick sections in one operation, without a change in color. With almost no odor during application, it hardens at room temperature, but in order to get the full mechanical properties (excellent resistance to thermal and physical shocks,) a post-cure from 40 to 80 oC is advised.
Curing time:
Curing time depends on the quantity of mix for casting, geometry of the part, thermal conductivity of mould and ambient temperature. SR Green Cast 160 / SD7160 system is very slow on small castings. To reduce cycle time, we advise to try several levels of temperature during the cure, in order to control the exothermic temperature in the part.
Advised post cure cycle:
Let cure at ambient temperature. Then increase the thermal properties of the system by a post-cure of 24 hours 40 oC or 8 hours at 40 oC + 12 hours at 60 oC.
