EZ-Brush® Vac Bag is a brushable, Platinum-Cure Silicone Rubber developed especially for fabricating reusable vacuum bags by hand. No spray equipment is required. EZ-Brush® Vac Bag Silicone has a 1A:1B by volume mix ratio and is easy to mix and apply. Mixed rubber is thixotropic and can be applied with a brush or spatula to vertical surfaces without sagging.
Production-ready vacuum bags can be fabricated fast using EZ-Brush® Vac Bag Silicone resulting in tremendous time and labor savings. Since bags are reusable, long term material costs are greatly reduced.
