Primer for glass

Black Glass Primer (30 ml) is a professional-grade adhesion promoter specially formulated to enhance bonding strength for direct glazing, windscreen installation, and polyurethane sealants. This black primer provides exceptional initial tack and outstanding UV resistance to protect the adhesive bead from solar degradation. Engineered free from chlorinated hydrocarbons and aromatic solvents, it is an indispensable prep product when applying 1-component or 2-component polyurethane adhesives onto glass, fiberglass, painted metals, and select plastics.

Acts as a vital protective and binding bridge between the substrate and polyurethane sealants while offering excellent paintability.

Key Features & Benefits:

• Enhanced Adhesion: Significantly improves bond strength on glass, fiberglass, metal, and painted substrates.
• UV Shielding: Protects the underlying polyurethane adhesive from UV breakdown over time.
• Safe Chemical Formula: Free of chlorinated hydrocarbons and aggressive aromatic solvents.
• Multi-Substrate Bonding: Compatible with various automotive plastics, metals, and clearcoats (pre-test recommended).
• Mixing Balls Included: Ensures smooth homogenization of ingredients prior to application.

Application Guidelines:

1. Ensure the substrate is thoroughly dry, clean, and completely free from grease, dust, and contaminants.
2. Shake the container vigorously until the internal steel mixing balls rattle freely. Stir/shake before each application to avoid sediment settling.
3. Apply a thin, uniform coat using a felt applicator, brush, or spray gun.
4. CRITICAL: Do NOT wipe or re-apply over an already dried coat! Re-coating reactivates the dried primer and negatively compromises adhesion. Uneven coats slow down curing times.
