YJS-T28 brushable RTV-2 Silicone Rubber
Description
YJS-T28 is a brushable tin silicone rubber that self-thickens for making fast brush-on molds of almost any model. Properly applied, it will hold a vertical surface and will reproduce the finest detail. Mixed 100A:2B by weight, rubber quickly develops thixotropy and can be applied with a brush or spatula. Working time is 6 - 8 minutes. Cure time after the final layer has been applied is 1-2 hours at room temperature. YJS-T28 silicone will not stick to most surfaces and will cure with negligible shrinkage to a strong, flexible Shore 28A rubber. 4 thin layers is all that is necessary to make a strong and durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.).
Important: you must weigh Part A & B components using a gram scale to be successful with YJS-T28.
