2K Filler Hardener

Uniform Deep Curing: Eliminates the risk of solvent trapping in thick undercoat applications, ensuring zero shrinkage or mapping after final painting.

Excellent Sanding Behavior: Delivers a hard yet perfectly sandable finish, minimizing labor and ensuring a smooth flat surface.

Superb Intercoat Adhesion: Enhances the chemical bonding between the metal substrate (or body filler) and the subsequent basecoat.

Enhanced Production Throughput: Considerably reduces air-drying and force-drying schedules in spray ovens for 2026 refinish operations.

Moisture Insulation: Forms a dense protective barrier that protects underlying steel panels from humidity and rust propagation.

Essential chemical curing agent for 2K acrylic primers and high-build polyurethane fillers used on passenger cars and commercial transport fleets.

Surface preparation for industrial equipment, steel structures, and marine elements requiring a flat, ultra-smooth foundation.

Specialized integration within automotive workshops, collision repair centers, and OEM refinishing facilities.

Direct procurement integration for municipal tenders, manufacturing supply chains, and bulk automotive paint distribution in Egypt.

Precise Volumetric Mixing: Add 2K Filler Hardener to the CMB 2K Filler base according to the exact volumetric ratios specified in the filler’s technical data sheet (e.g., 4:1 or 5:1). Stir thoroughly to achieve a homogeneous mixture.

Viscosity and Pot Life: After introducing the hardener and diluting with compatible acrylic thinners, spray immediately within the specified "Pot Life" window to prevent curing inside the spray gun.

Spraying Setup: Apply using a primer spray gun (nozzle size: 1.6 mm to 1.8 mm) in medium to high-build coats, allowing proper flash-off times between coats.

Sanding Window: Sanding should only be executed once the filler film is fully cured (typically 3–4 hours of air dry at 25°C or 30 minutes at 60°C oven bake).
