LIOPTAL A 471

Lioptal A471 is a heat-reactive high-solids acrylic resin designed to cure with amino resins or blocked polyisocyanates. Here's an overview of its technical specifications:

Characteristics:

• • Heat-reactive high-solids acrylic resin, curable with amino resins or blocked polyisocyanates.

Supplied as: 70% in Shellsol A/Butanol (25:5).

Use:

• • Utilized in combination with blocked polyisocyanates or melamine resins for stoved finishes with high flexibility, color stability, and weathering resistance. Stoving conditions typically above 130°C. Used for metal substrates as a base coat and topcoat for high solid automotive and industrial coatings.

Properties:

• • Viscosity: 1,100 – 1,500 mPas (as supplied).
  • Color value (Hazen): Maximum 50 (as supplied).
  • Non-volatile constituents: 69 – 71% (as supplied).
  • Flash point: Approximately 33°C (as supplied).
  • Density: Approximately 1.02 g/ml (as supplied).
  • Acid value: 8-12 (relative to non-volatile constituents).

These characteristics make Lioptal A471 suitable for applications requiring heat-reactive acrylic resins with high solids content, particularly in automotive and industrial coatings where flexibility, color stability, and weathering resistance are crucial.
