BASONAT® HI 2000 NG is a solvent-free, low viscosity aliphatic polyisocyanate for lightfast and weather-resistant two-pack polyurethane coatings. Results from weathering tests show that in most cases, gloss retention is better using isocyanurates than with biurets of hexamethylene diisocyanates (BASONAT HB grades). Acrylic polyols should be used for maximum weather resistance.

Combined with conventional acrylic resins, a solids content of approximately 3% higher than with BASONAT® HI 100 NG can be achieved. The use of high solids binders such as JONCRYL or Sovermol polyols allows the solids content to be increased even further.

BASONAT HI 2000 NG  is recommended for applications such as:

• Interior/exterior automotive OEM or refinish applications
• Interior/exterior plastic component coating applications
• Interior/exterior general industrial metal coating applications
• Interior/exterior wood coatings for floor, furniture, or millwork applications

Features & Benefits

• Lower viscosity for low VOC coatings
• Excellent weather and chemical resistance
• Excellent color stability in formulated automotive refinish clear coat hardeners
• Excellent hardness/flexibility for demanding applications
