Spectrem 1 Precast White, 20 oz sausage
Tremco Spectrem 1 is a high-performance, single-component, moisture-cure, ultra-low modulus silicone sealant. It is used on dynamically moving joints in aluminum curtainwalls, precast concrete, metal panels, and window perimeters. Ultra-low modulus holds +100/-50% movement, and a slight grain finish lets the bead zipper rather than fully tear if a joint fails.
