Calvana Windscreen Primer 1 fl.oz Black — Fast-Drying Urethane Adhesion Promoter, UV-Resistant Kit with Gloves

Calvana 1 fl.oz Windshield Primer is a fast-drying urethane adhesion promoter formulated to improve bond strength between automotive glass and polyurethane sealants while offering UV resistance and corrosion protection.

This compact primer kit is designed for windshield replacement and glass repair tasks where dependable adhesion, quick handling time, and added surface protection matter. The single-component formula requires no separate activator, dries quickly, and comes with applicator daubers and nitrile gloves so you can begin prepping glass and pinchwelds right away. It works on exposed glass edges, encapsulated glass, and small scratched areas to help sealants adhere and resist UV-related breakdown.

How quickly does the Calvana primer dry and become ready for urethane sealant?

The primer is engineered for fast surface flash-off so technicians and DIYers can proceed without long waits. Typical handling time is short — the primer sets up in minutes under normal shop conditions, allowing you to apply the urethane adhesive soon after prep.

• Single-component formula—no activator required
• Surface ready in approximately 10 minutes under standard temperature
• Works well with provided applicator daubers for even coverage

Will this primer protect against UV and corrosion where glass meets the pinchweld?

Yes — the Calvana primer contains UV-resistant properties intended to help shield the urethane bead and the primed interface from sunlight exposure that can accelerate deterioration. It also helps seal minor scratches on pinchwelds and bare metal to slow corrosion before the sealant cures.

• UV-resistant formulation to reduce sun-related degradation
• Suitable as a blackout primer for exposed edges
• Helps prevent corrosion on small scratch areas of pinchwelds

How do I apply the primer for best adhesion results?

Surface preparation is key: clean the glass and pinchweld thoroughly, remove contaminants, and use the included daubers to apply a thin, even layer of primer. Allow the primer to flash off until tack-free, then install your polyurethane sealant according to the adhesive manufacturer's instructions.

• Use supplied nitrile gloves to avoid contamination
• Apply thin, uniform coats with included 5.9" applicator sticks
• Ensure surfaces are dry and free of oils, dust, and old adhesives

Is this product compatible with common auto glass urethane adhesives?

Calvana's windshield primer is formulated to promote adhesion with polyurethane-based adhesives commonly used in windshield installation. It is intended for use as a preparatory coat; always follow the adhesive manufacturer's compatibility and cure-time guidelines for the best results.

• Developed to enhance polyurethane sealant bonding
• Useful for both OEM-style and aftermarket urethane adhesives
• Included tools streamline application for technicians and DIYers

Who is this for? Calvana 1 fl.oz Windshield Primer is well suited to auto glass professionals, body shops, and competent DIY installers who need a compact, quick-curing adhesion promoter for windshield replacements, glass repair, and pinchweld protection. The kit-sized format with gloves and applicators makes it useful for single jobs, service vans, or as a complement to a full polyurethane adhesive kit when you want reliable adhesion and UV resistance without bulky packaging.
