Shelf life                   
      Basonat® HI series must be stored in airtight containers due to their sensitivity to humidity. The product can be stored at 10°C to 30°C for at least six months in the unopened original packaging. The shelf life of the product may be shortened after opening.

 Other properties  

The NCO equivalent characterizes the weight of Basonat® in the supplied form corresponding to 1 mole of active NCO groups.

  cross-linking                         
     Basonat® HI series can be used to crosslink most hydroxy acrylic resins, as well as hydroxy polyesters.

Dilution tolerance                    
     Basonat® HI series can be diluted with ester solvents such as butyl acetate, ketone solvents such as methyl ethyl ketone, glycol ether esters, aromatic solvents such as Solvesso® 100 or xylene. Basonat® HI series is not recommended to be diluted to less than 40% isocyanate content, otherwise turbidity, flocculation, and precipitation may occur during storage. Different storage conditions will result in different storage stability of the product.

  application                   
      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 certain hydroxyl-containing polyester resins. Basonat® HI 100 is solvent-free and has a wide choice of solvents for applications. For example, for furniture coatings, slow-evaporating solvents may affect the drying properties of the coatings. In this case, fast-evaporating solvents can be used. Test results show that in most cases, the gloss retention of Basonat® HI series is better than that of biuret isocyanates (Basonat® HB series). Basonat® HI series has a lower viscosity than Basonat® HB series, making it more suitable for solvent-free coatings.

  Matching ratio                       
       Calculate the equivalent amount of isocyanate theoretically used for cross-linking. 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]

0.075 ×70 ×135/22=32.2
 

Amount of hardener required for 100 grams of Macrynal® SM 636:

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

  safety warning
      Basonat® HI series are reactive and functional isocyanates containing trace amounts of hexamethylene diisocyanate, so adequate protection measures are required in application. They can only be used in industrial and professional fields and are not suitable for DIY operations. When applying these products, the information and recommendations in the Product Safety Data Sheet should be consulted in advance. In addition, the application site should have adequate hygiene and protection measures.
