BASF HB 175 MP/X biuret curing agent; Basonat HB 100 solvent-free curing agent

Chemical Structure
  Polyisocyanate obtained by polymerizing hexamethylene diisocyanate

series

physical form
Liquid

Shelf life
Basonat® HB series must be kept in airtight containers as they are 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

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

Crosslinking
Basonat® HB series can be used to crosslink most hydroxyl acrylic 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 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® HB series can be used to formulate coatings with high light and weather resistance. Aliphatic isocyanates are sometimes used as primers on various substrates such as aluminum, various plastics, polymers, etc.
Basonat® HB 100 can be used where Basonat® HB 175MP/X solvents are not suitable. (For example, aromatic solvents can dissolve polystyrene)

ratio
Calculate the theoretical equivalent amount of isocyanate required for crosslinking, 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
The amount of curing agent required relative to 100 grams of Macrynal® SM 636: Basonat® HB 100 32.2 grams, Basonat® HB 175 MP/X 43.0 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® HB 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.
