TREMprime Non-Porous Primer – Ultimate Adhesion for Metal, Glass & Plastic Substrates
Achieve fail-safe bonds on challenging non-porous surfaces with TREMprime Non-Porous Primer. This innovative, one-part, water-based primer is specifically formulated to create a powerful adhesive bridge between smooth substrates like metal, glass, and plastic, and Tremco's range of polyurethane sealants and membranes. Its ultra-low viscosity ensures easy application and optimal surface preparation where traditional primers struggle.
With an exceptionally low VOC content of just 7g/L and Green Star compliance, TREMprime Non-Porous Primer offers an environmentally conscious choice without compromising performance. It's the essential first step for ensuring the long-term durability and reliability of waterproofing systems on metal cladding, window frames, and plastic composites.
Key Features & Benefits:
- Superior Adhesion on Non-Porous Surfaces: Specifically engineered to bond polyurethane products to metal, glass, plastic, and other smooth substrates.
- Ultra-Low VOC & Water-Based: With only 7g/L VOC, it is safer for applicators and ideal for use in confined spaces and environmentally sensitive projects.
- Green Star Compliant: Meets the requirements for sustainable building projects, contributing to Green Star certification credits.
- Fast Recoat Time: Allows for sealant or membrane application just 15 minutes after priming under standard conditions.
- Easy Application & Clean-Up: Can be applied with a clean cloth and cleans up easily with water, simplifying the priming process.
- Clear & Non-Staining: Dries to a clear film, leaving no residue or color, making it ideal for visible applications.
Primary Applications:
- Metal Substrates: Priming aluminum, steel, and galvanized metal cladding, flashings, and window frames before sealant application.
- Plastic & Composite Materials: Preparing PVC, fiberglass, acrylic, and other plastic-based building products.
- Glass Surfaces: Enhancing adhesion on glass structures and assemblies.
- Pre-Waterproofing Preparation: Essential primer for ensuring membrane adhesion on non-porous surfaces in balcony, podium, and roof applications.
