Chemlease® MPP 2180 – Mold Primer (Heavy-Duty Surface Sealer Basecoat)

Chemlease® MPP 2180 is a heavy-duty mold primer designed to prepare and seal mold surfaces before the application of semi-permanent mold sealers and release agents. It improves process efficiency and finished part quality by creating a smooth, non-porous, uniform substrate that helps subsequent release coatings perform consistently across production cycles.

What It’s For

• Sealing and priming composite and metal molds prior to semi-permanent sealer/release application.
• Excellent on polyester, epoxy, phenolic, and metal molds, plus RenShape®/urethane tooling boards.
• Ideal for new tools, refurbished tools, or molds that exhibit porosity, inconsistent release, or surface micro-defects.

Important: MPP 2180 is a primer only and does not have release properties. Follow with a compatible Chemlease® mold sealer and release agent to complete the system.

Key Benefits

• Creates a smooth, non-porous surface that enhances sealer/release performance.
• Promotes consistent demolds and helps reduce sticking and print defects.
• Supports extended tool life and improved cosmetic finish quality.
• Streamlines new-tool startup and mold refurbishment.

Typical Application (Summary)

1. Clean & de-wax the mold thoroughly; remove contaminants, residue, and oxidation. Allow to dry.
2. Apply MPP 2180 per the manufacturer’s instructions (wipe-on with lint-free applicator or HVLP spray, thin even coats).
3. Allow appropriate flash/cure time between coats. (Number of coats depends on substrate porosity and TDS guidance.)
4. Top-coat with the recommended Chemlease® mold sealer, then finish with a compatible release agent.
5. Verify with a small test area before full-scale production to confirm process settings and finish.

Compatibility

Suitable for polyester, epoxy, phenolic, and metal tools as well as RenShape® epoxy and urethane tooling boards. Always consult the product TDS/SDS for exact parameters, cure times, and compatibility with your chosen sealer/release system.

Handling & Safety

• Use in a well-ventilated area with appropriate PPE (gloves, eye/skin protection).
• Avoid open flames and ignition sources. Follow local regulations for storage and disposal.
• Refer to the most current TDS/SDS for detailed instructions and safety information.
