The SG 22015 slow curing polyurethane casting resin is a slow variant of the fast curing casting resin SG 140 or SG 2000L that can be used for many applications. This HS (high strength) unfilled resin is perfect for making molds, models, control models, prototypes, negative and positive models, casting molds and boxes, casting patterns and tools! The easy to mix 1A:1B by weight (100:88 by volume) resin has a Shore D 70 hardness. The SGPU 22015 is a casting product with a low viscosity of 60 mPas and a 10-15 minute pot life at 200 grams of processing. The curing or demold time is between 3-5 hours.
The SGPU 22015 is a yellowish product and lends itself well to processing it with color pigments or bronze powders. Finishing the cured material is also an easy option. The SGPU 22015 urethane is a room temperature curing (RTV) polyurethane material.

Stir both components A and B separately until the viscosity can be compared with each other before you pour these A + B together. When using filler, first stir both materials well and then mix with filler. If you have not worked with these materials before, first stir the filler with 1 component well and only then mix the components. For thin casting thicknesses of < 3 mm, we recommend using another product such as the EasyFlo or SG 140 .
