The NCO equivalent weight indicates the amount of Basonat® polyisocyanate as supplied containing 1 Mol of active NCO.

Application

Basonat® HI 100 is a solvent free isocyanurate oligomer.

Basonat® HI 100 allows a broad choice of solvents. For instance, when less volatile solvents would retard drying excessively, like in furniture coatings, highly volatile solvents can be chosen.

Basonat® HI grades are used to formulate particularly lightfast andweather-resistant coatings.

Basonat® HI polyisocyanates are used to crosslink most hydroxy group containing resins, e.g. acrylate resins like the Joncryl® Polyols and hydroxy polyesters like the hyperbranched Basonol HPE Polyesters. Sufficient compatibility withpolyester resins containing hydroxylgroups is not always given.

Formulation guidelines

Basonat® HI polyisocyanates can be diluted with esters (e.g. butyl acetate), ketones (e.g. methyl ethyl ketone), glycolether acetates (e.g. methoxypropylacetate) or with aromatic hydrocarbons (e.g. Solvesso®1 100, xylene).

If Basonat® HI polyisocyanates are diluted to a polyisocyanate fraction of less than 40%, turbidity, flocculation and/or sedimentation may occur during storage. Storage trials should always be carried out.

Results from long-term weathering tests show, that in most cases gloss retention is better with isocyanurates than with polyisocyanates based on biurets of hexamethylene diisocyanate (Basonat® HB grades). In addition, due to the low viscosity the solid content can be increased when Basonat® HI grades are used instead of Basonat® HB grades.

The theoretical equivalent amount of polyisocyanate required for crosslinking is computed using this formula:

0.075 x [OH value] x [non volatile fraction of OH component]

[NCO]

example: Joncryl® 507

OH value [mg KOH/g polyol on solids]

140

non-volatile fraction (nvf) [%]

Basonat® HI 100 , NCO content [%]

22

Dosage rate for 100 g Joncryl® 507 as supplied is 38.2 g of Basonat® HI 100.

Solvents, pigments or extenders etc. used, should be free from compounds containing active hydrogen groups, e.g. water, alcohols oramines.

A water content of less than 500 ppm in solvents and binders is recommended for 2K polyurethane lacquers.
