Product Description
Special Anti-Corrosion Coating, Hollow Glass Bubble, HN32HS, Tooling Board, Thermoplastic
Corrosion presents significant challenges across industries, damaging equipment and structures while causing costly repairs and downtime. Our special anti-corrosion coatings provide an effective protective barrier against corrosion, preventing moisture and corrosive agents from reaching the substrate.
Incorporating hollow glass bubbles enhances coating barrier properties. The bubbles' low density reduces coating weight, enabling thicker application layers without adding substantial weight. These thicker layers deliver superior protection against moisture and corrosive agents, significantly reducing corrosion risk.
Applications
- Epoxy coatings: Commonly used for steel and metal anti-corrosion protection. Hollow glass bubbles improve barrier properties, impact resistance, and thermal insulation. Example: 3M™ Scotchkote™ Epoxy Coating 323.
- Urethane coatings: Another metal protection solution where hollow glass bubbles enhance barrier properties while reducing weight for easier application. Example: PPG's PSX® 700 coating.
