Description
707-082 Duratec Light Grey Surface Primer – 1 Gallon
Duratec® 707-082 Light Grey Surface Primer is a high-build, easy-sanding air-cure primer designed for wood, MDF, tooling board, and composite plugs, patterns, and models. Engineered to deliver a smooth, glossy, pore-free surface, this primer is ideal as a surface coat for composite tooling or as a base for topcoats requiring the highest finish quality.
Using unique air-cure technology, Duratec Light Grey Surface Primer cures quickly—even in relatively thin coats—so parts can be sanded and polished to a high gloss in less time. The highly cross-linked film offers excellent chemical resistance and long-term durability, making it a reliable choice for demanding production and prototype environments.
Key Features & Benefits
- High-build, fast-sanding primer: fills surface imperfections and sands easily to a perfectly smooth profile.
- High-gloss surface potential: can be polished directly to a gloss or used as a base for high-gloss topcoats and mold surfaces.
- Air-cure technology: fast cure even at thin film builds, helping reduce turnaround time on plugs and patterns.
- Excellent adhesion: bonds to wood, MDF, composite laminates, tooling board, concrete, and polyurethane foam.
- Defect-free finish: provides a porous-free surface that resists pinholes and surface defects.
- Chemical resistance: highly cross-linked coating offers excellent chemical and solvent resistance.
- Versatile application: can be sprayed with HVLP equipment, or applied by brush or roller when required.
- Filler substitute: effective alternative to epoxy or polyurethane fillers on profile-free surfaces.
Recommended Uses
- Surface primer for composite plugs and patterns used in mold construction.
- High-build primer for MDF and tooling board before final topcoat or mold release systems.
- Primer for wood, MDF, brick, concrete, and polyurethane foam in model and pattern shops.
- Sanding and polishing base for high-gloss mold or prototype finishes.
