LERSAISFANY Windshield Primer Kit 50 mL Black Urethane Adhesion Promoter - Fast-Drying Single-Step

LERSAISFANY Windshield Primer Kit is a one-part urethane adhesion promoter that prepares glass, metal, and PVC surfaces for faster, stronger windshield and encapsulated glass installations.

Engineered for technicians and DIYers replacing or repairing automotive glass, this compact kit delivers a black, fast-drying primer that bonds urethane adhesives to pinchwelds, extrusion welds, and PAAS systems without an extra activator. The formula adds UV protection and corrosion resistance to help maintain adhesive performance, while the included applicators and nitrile gloves make single-panel jobs simple and tidy.

How does this primer improve windshield adhesion?

The primer increases chemical wetting and surface compatibility so urethane adhesives cling more consistently to varied substrates. That stronger initial bond reduces the risk of gaps and improves the cure footprint for subsequent adhesives.

• Promotes urethane chemical bonding to glass, metal, and PVC.
• Optimizes wetting on pinchwelds and encapsulated edges.
• Reduces potential adhesive lift and improves seal continuity.

How fast does the LERSAISFANY primer dry, and is any mixing required?

This is a single-component primer that cures in about 10 minutes under normal conditions, eliminating the need for on-site mixing or activators. The quick tack time lets installers move to adhesive application sooner while maintaining a controlled workflow.

• One-part formula — no activator or catalyst needed.
• Approximate cure time: 10 minutes at room temperature.
• Ready-to-use bottle reduces preparation steps and waste.

What surfaces and repair jobs is the kit suitable for?

The primer works across common automotive substrates, making it suitable for windshield replacements, PAAS and encapsulated glass systems, and PVC trims. It’s also appropriate for touch-ups where corrosion or UV degradation might compromise adhesive bonds.

• Glass windshields and backlites.
• Pinchwelds, extrusion welds, and metal frames.
• Encapsulated parts, PAAS systems, and PVC components.

What comes in the kit and what safety steps should I follow?

The kit contains a 50 mL black urethane primer bottle, two applicator daubers for controlled application, and a pair of nitrile gloves to protect hands from primer contact. Standard PPE like eye protection and a respirator mask is recommended during application to prevent inhalation and contact.

• 50 mL black urethane primer bottle included.
• Two applicator daubers for even, precise coating.
• Nitrile gloves included; wear eye protection and a mask.

Who is this for: The LERSAISFANY Windshield Primer Kit is aimed at auto glass technicians, mobile installation pros, and knowledgeable DIYers who need a compact, reliable adhesion promoter for windshield and encapsulated-glass work. It’s especially useful for small jobs, touch-ups, and situations where a fast-curing, single-component primer streamlines prep without sacrificing bond performance.
