Features Of Mitsubishi HR7130 Thermoset Acrylic Resin

  1. Excellent thermal stability and long-term heat resistance up to 180 °C continuous service temperature.

  2. High crosslink density enabling superior hardness, chemical resistance, and solvent resistance in cured films.

  3. Low volatile organic compound (VOC) content, supporting compliance with stringent environmental and regulatory standards.

  4. Consistent batch-to-batch reproducibility and excellent storage stability at ambient conditions.

  5. Optimized reactivity profile for efficient curing with common amino crosslinkers (e.g., melamine-formaldehyde resins).

Typical Applications Of Mitsubishi HR7130 Thermoset Acrylic Resin

  1. Automotive OEM topcoats and clearcoats requiring high gloss retention and weatherability.

  2. Industrial coil coatings for pre-painted metal used in building panels and appliances.

  3. High-performance can coatings for food and beverage containers.

  4. Electrical insulation coatings for motor windings and transformer components.

  5. Powder coating base resins for architectural aluminum extrusions and durable outdoor fixtures.
