Chemical Structure                                                                                                Polyisocyanate polymerized from hexamethylene diisocyanate

Series

Physical form                                                           Liquid

Shelf Life  
         Basonat® HB series must be stored in an airtight container as it is sensitive to humidity. In the original unopened packaging, the product can be stored at a temperature of 10°C to 30°C for at least six months. After opening, the shelf life of the product may be shortened.

Product Specifications

Basonat® HB 100

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

Cross-linking                                                           Basonat® HB series can be used to cross-link most hydroxyacrylic resins, as well as hydroxyl polyesters.

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

Application
Basonat® HB series can be used to formulate coatings with high light and weather resistance. Aliphatic isocyanates are sometimes used as primers on different substrates, such as aluminum, many plastics, polymers, etc.
Basonat® HB 100 can be used in situations where Basonat® HB 175MP/X solvent is not suitable. (For example, aromatic solvents can dissolve polystyrene)

Proportion                                                                                             Calculate the theoretical equivalent amount of isocyanate required for cross-linking. Taking Basonat® HB100 and Macrynal® SM 636 as examples, the calculation formula is as follows: 0.075 [OH value]* [Hydroxy resin solid content]/ [NCO]
For example: Macrynal® SM 636

0.075×70×135 /22=32.2
Amount of hardener required relative to 100 g of Macrynal® SM 636: Basonat® HB 100 32.2 g,Basonat® HB 175 MP/X 43.0 It must be noted that any solvents, pigments and other additives in the formula do not contain active hydroxyl groups, such as water.

Safety Tips
Basonat® HB series contains trace amounts of hexamethylene diisocyanate, which are reactive and functional isocyanates, so sufficient amounts are required in the application. Safeguard. They are intended for industrial and professional use only and are not suitable for DIY operations. When using 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 protective measures.
