HI Series High light and weather resistant aliphatic polyisocyanate for 2K polyurethane coatings
Basonat® HI series can be used to formulate coatings with high lightfastness and weatherability. Basonat® HI 190 B/S is a solution of Basonat® HI 100. Basonat® HI series may be incompatible with certain hydroxyl-containing polyester resins. Basonat® HI 100 is solvent-free and has a wide choice of solvents for applications. example When used in furniture coatings, slow evaporating solvents may affect the drying properties of the coating, page 3 of 4 Basonat® HI Series A fast-evaporating solvent may be used. Test results show that in most cases, the gloss of Basonat® HI series Better retention than biuret isocyanates (Basonat® HB series). Basonat® HI series has a lower viscosity than Basonat® HB series, making it More suitable for solvent-free coatings.
