Industrial Powder Coating
De-Gassing Powder Coating
Durable · Smooth · High-Performance Finishes
Formulated to minimize pinholes on porous substrates. Sharp Coatings’ de-gassing series is engineered with additives and flow control to release entrapped gases during cure, helping to prevent pinholes, cratering, and fish-eyes on challenging substrates such as cast aluminum, hot-dip galvanized (HDG) steel, and weld-heavy fabrications. The result is a smoother, more uniform film and a reliable first-pass yield on production lines.
Benefits
Prevents Pinholes & Cratering
Specially formulated to minimize surface defects such as pinholes and craters, ensuring a smooth and defect-free coating finish.
Optimized for Porous Metals
Designed to perform effectively on porous and cast metal substrates, improving coating consistency and appearance.
Smooth, Uniform Surface Appearance
Provides excellent flow and levelling characteristics for a consistent, high-quality finish across the entire surface.
High First-Pass Yield
Reduces rework and rejects by delivering reliable coating performance and excellent coverage in a single application.
Compatible with Standard Spray Lines
Works seamlessly with conventional powder coating equipment and application systems without requiring process modifications.

Frequently Asked Questions
Ans. Porous metals like cast aluminium or HDG steel can trap air, moisture, or oils that are released
during curing, forming pinholes or craters in the coating film.
Ans. These formulations contain specialized additives that promote the release of trapped gases
during melt, allowing them to escape before film formation completes.
Ans. Pre-baking can help remove deep-seated volatiles, but in many cases, de-gassing powders
alone are sufficient to achieve a smooth finish.
Ans. Yes, available in epoxy-polyester, and pure-polyestyer chemistries, suitable for both
interior and exterior applications.
Ans. No. De-gassing powders deliver excellent flow and gloss consistency, resulting in a smooth,
professional finish without surface defects.
