Key Features

• Color: Black

• Base: Solvent-based polyurethane solution

• Solid Content: ~27 %

• Pack Size: 250 ml bottle

Benefits

• Enhances adhesion on many substrates (glass, metals, plastics, painted surfaces, pre-coatings, E-coats)

• Fluoresces under long-wave UV light for easy coverage inspection during application

• Easy to apply with a brush, felt or foam applicator

Typical Data

Application & Use

• Designed to improve adhesion before applying Sika 1-component polyurethanes (e.g., auto glass urethane adhesives)

• Suitable for professionals; material compatibility tests on actual substrates recommended

Technical Specs

• Coverage: ~50 ml/m (varies with substrate porosity)

• Flash-off Time: Minimum ~10 min above 5°C up to 24 h, depending on conditions

• Shelf Life: ~12 months unopened under proper storage

Usage Tips

1. Surface Prep: Make sure substrates are clean, dry, and free of grease or contaminants.

2. Apply Thinly: Use a brush or felt applicator to apply a thin, even coat.

3. Flash-off: Allow primer to flash off (become tack-free) before adhesive application.

4. UV Check: The UV fluorescence helps confirm coverage.

Typical Applications

• Automotive windshield and glass bonding preparation

• Priming metal and painted surfaces before sealing or adhesive work

• Use with polyurethane sealants for improved bond strength
