Spectrem 4-TS Sealant – Product Description

Spectrem 4-TS is a multi-component, low-modulus, neutral-cure silicone sealant designed to deliver long-lasting performance and non-staining sealing on porous substrates. It is ideal for dynamic commercial applications where weatherability, movement, and finish quality are critical. This silicone formula combines flexibility, adhesion, and aesthetics in a product that installers trust for critical joints and perimeter transitions.

The product’s unique chemistry allows field tinting in up to 70 colors using Tremco’s Universal Color Paks. This makes it easy to match building design specifications or blend the sealant into textured substrates such as EIFS or precast panels. Whether applied vertically, horizontally, or around curved surfaces, Spectrem 4-TS maintains excellent elasticity and adhesion with minimal dirt pickup.

Why Use Spectrem 4-TS?

Spectrem 4-TS is formulated for easy application using common caulking tools and has an extended tooling window for neat installation. Its textured finish creates a subtle, blended appearance that enhances the visual appeal of sealed joints. The sealant performs well in high-movement conditions, offering ±50% movement capability without cracking or loss of adhesion. Plus, it carries a 20-year non-staining warranty when used in approved assemblies and tested per ASTM C1248.

Contractors appreciate its user-friendly application characteristics, while specifiers rely on its GREENGUARD certification for indoor air quality, making it ideal for hospitals, schools, and clean environments. From expansion joints to tilt-up panels, Spectrem 4-TS delivers professional results and long-term protection.
