BASF hardener

Solvent free aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI)

Product Description

1,6-hexamethylene diisocyanate based polyisocyanate is a solvent free aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI), colorless to slightly yellowish clear liquid.

Application

the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties. Preferred co-reactants are polyacrylates or polyester polyols. The main applications for coatings are automotive refinishing, transportation, industrial finishing and plastics

Storage in original container. Protect from moisture, heat and foreign material. HT-100 is sensitive to moisture. Storage at higher temperatures may result in increasing of color and viscosity.HT-100 can be thinned with esters, ketones and aromatic hydrocarbons such as ethyl acetate, butyl acetate, methoxypropylacetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, solvent naphtha 100 and mixtures thereof. Generally speaking, it has good compatibility with the solvents listed. However, the solutions formed must be tested for their storage stability. Only PU grade solvents should be used (max.0.05% water, absence of reactive groups such as hydroxyl or amino groups). Aliphatic hydrocarbons are unsuitable as solvents. HT-100 is not recommended to be thinned to a lower solid content. Prolonged storage of a solution with a lower content may result in turbidity or sedimentation, even gelation.
