Basonat® HI 190 B/S

style=”font-size:16px”>
  Basonat® HI series can be used to formulate coatings with high light and weather resistance. Basonat® HI 190 B/S is a solution of Basonat® HI 100. Basonat® HI series may be incompatible with some hydroxyl-containing polyester resins. Basonat® HI 100 is solvent-free and allows a wide choice of solvents in the application. For example, for furniture coatings, slow volatile solvents may affect the dryness of the paint, and fast volatile solvents can be used at this time. Test results show that, in most cases, the gloss retention of Basonat® HI series is better than that of biuret-based isocyanates (Basonat® HB series). Basonat® HI series has lower viscosity than Basonat® HB series, making it more suitable for solvent-free coatings.

ratio
Calculate the theoretical equivalent amount of isocyanate required for crosslinking, taking Basonat® HI100 and Macrynal® SM 636 as examples, the calculation formula is as follows: 0.075 ×[ OH value] × [solid content of hydroxyl resin]/ [NCO]

Example: Macrynal® SM 636

NCO content (DIN EN ISO 11909)	19.3 -20.3%

Solid content% of hydroxyl resin	70
OH value	135
Basonat® HI 100, NCO%	22

0.075 ×70 ×135/22=32.2

The amount of curing agent required for 100 grams of Macrynal® SM 636:

Basonat® HI 100	32.2 gram
Basonat® HI 190 B/S	35.8 gram

It must be stated that any solvents, pigments and other additives in the formula do not contain active hydroxyl groups, such as water.

Security Tips
Basonat® HI series is a reactive and functional isocyanate containing trace amounts of hexamethylene diisocyanate, so it needs to have enough Safeguard. They can only be used in industrial and professional areas, not suitable for DIY operation. When using these products, the information and recommendations in the product safety data sheets should be consulted in advance. In addition, adequate sanitation and protective measures should be taken at the application site.
