Rockhard Fusion Primer – Fast-Drying Adhesive Primer
Rockhard Fusion Primer is a cutting-edge, fast-drying adhesion primer designed to function as either an intercoat primer or a direct-to-substrate primer. Its thin sol-gel formula creates a molecular bond between coatings and substrates, chemically fusing them for superior adhesion. Whether applied between layers or directly onto surfaces like concrete, wood, aluminum, and more, this primer enhances coating performance without the need for sanding or mechanical abrasion.
Key Features & Benefits
- UV Stable & Nearly Invisible – Provides adhesion without altering the appearance
- No Sanding Required – Eliminates the need for mechanical abrasion before top coating
- Strong Bonding – Adheres to hard-to-bond, low/no-profile surfaces
- Fast Overcoat Time – 90-minute overcoat window; if missed, lightly abrade and reapply
- Covalent Bonding Technology – Forms a molecular connection with the substrate, creating a durable barrier
- Versatile Application – Suitable for concrete, steel, stone, tile, glass, and more
- Deep Surface Penetration – Enhances adhesion and longevity of coatings
Compatibility & Considerations
- Works with most coatings but not compatible with water-based topcoats
- No surface profiling required for clean concrete free of oils, grease, or bond breakers
- High-VOC content – Ensure proper ventilation for indoor applications
Applications
Ideal for use on:
✔ Painted & unpainted metals – Iron, aluminum, copper, stainless steel, hot/cold rolled steel
✔ Powder-coated & galvanized surfaces
✔ Concrete, wood, rubber, plastic, fiberglass, and glass
Rockhard Fusion Primer delivers exceptional adhesion, durability, and ease of use, making it the perfect solution for high-performance coating applications.
