Calvana 1 fl.oz Windshield Primer

Calvana 1 fl.oz Windshield Primer is a fast-drying urethane adhesion promoter that prepares automotive glass and pinchwelds for durable polyurethane sealing while including gloves and applicators for immediate use.

This compact automotive primer is formulated to boost adhesion between polyurethane sealants and windshield glass or vehicle pinch weld surfaces. It arrives as a single-component, black primer that dries quickly without an activator and offers UV resistance to help protect bonded joints from sunlight-related degradation. The kit includes a pair of nitrile gloves and two 5.9-inch applicator sticks so you can start a windshield replacement or repair job right away.

How does this primer improve windshield adhesion?

The primer chemically prepares glass and painted or bare metal pinch welds so polyurethane adhesives form a stronger, more consistent bond. Using the primer reduces the chance of adhesive failure caused by surface contamination or insufficient wetting.

• Promotes polyurethane wet-out on glass and PVC surfaces
• Black formulation doubles as a blackout primer for optical concealment
• Applied with included daubers for even, controlled coverage

How fast does it dry and what are the application steps?

The single-component formula dries rapidly—typically within about ten minutes—so you can apply urethane adhesive quickly after primer application. No separate activator is required, which simplifies workflow for professionals and DIYers.

• Clean and dry the bonding surfaces before priming
• Use supplied applicator sticks to apply a thin, even coat
• Allow roughly 10 minutes to dry, then proceed with urethane adhesive

Will this primer protect against UV and corrosion?

Yes—Calvana’s primer includes UV-resistant components to help shield the adhesive and underlying substrates from sunlight exposure. It also helps prevent corrosion by sealing minor scratches on pinchwelds and encapsulated glass edges.

• UV resistance extends the life of the bonded joint
• Seals minor pinchweld scratches to inhibit rust formation
• Suitable for encapsulated glass and PVC trim priming

What comes in the kit and how long is it usable?

The package contains a 1 fl.oz. bottle of automotive urethane primer, one pair of nitrile gloves, and two 5.9-inch applicator sticks sized for precise application. For best performance, use the primer within six months after opening; the date printed on the bottle is the production date.

• 1 fl.oz. black urethane primer bottle
• Pair of disposable nitrile gloves included
• Two 5.9-inch applicator sticks for dauber-style application
