EZ-Brush™ Vac Bag Silicone

EZ-Brush™ Vac Bag Silicone is a brushable platinum cure silicone developed especially for making high performance, reusable vacuum bags. EZ-Brush™ Vac Bag Silicone is easy to mix and apply. Mix ratio is 1A:1B by volume and rubber can be applied with a brush or spatula to vertical surfaces without sagging.

Pot life is 30 minutes, recoat time is 1 hour. Rubber cures with negligible shrinkage to a soft, flexible rubber (Shore 20A) with very high elongation and tear strength. Newly made bags can be removed from the tool in 3.5 hours and used immediately in production with polyester or epoxy resin systems and will withstand temperatures up to 500° F /260° C.

Compared to conventional vacuum bagging systems, EZ-Brush™ Vac Bag Silicone is much faster at delivering a productionready silicone bag resulting in a tremendous time and labor savings. Since bags are re-usable, long term material costs are greatly reduced.
