Brush-On™ Series High Tear Strength Brushable Urethane Rubber

Smooth-On's Brush-On^TM Series of mold rubbers are extremely versatile and are famous for their abrasion resistance and high tear strength. They have the convenience of a one-to-one mix ratio and are easy to mix and apply with a brush or spatula. Brush-On^TM rubber paints onto vertical surfaces without sagging and will cure with negligible shrinkage to durable rubbers that perform and last in production. Each will capture exact detail from any original model.

Brush-On^TM40 is used for models with deep undercuts. Brush-On^TM 40 can be used to make glove molds. Brush-On^TM 50 and Brush-On^TM 60 possess superior abrasion resistance and tear strength and are ideal for casting concrete and hard plasters in applications where less flexibility is required. All three rubbers are suitable for reproducing sculpture, architectural restoration and production casting of concrete.

Brush-On^TM 35 Urethane Rubber is easy to mix and apply with a brush or spatula, paints onto vertical surfaces and will cure with negligible shrinkage to a durable rubber that performs in production. Applications for Brush-On^TM 35 include on-site architectural restoration molds, reproducing sculpture (lost wax process) and making special effects.
