Properties / Applications :

As a particularly low-viscosity polyisocyanate, Desmodur XP 2580 is

particularly well suited for the formulation of high-solids coatings for general industrial coating, automotive refinishing, transportation and plastics coating applications.

As with any product, use of Desmodur XP 2580 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Handling information:

This product contains reactive HDI polyisocyanate/prepolymer and/or

monomeric HDI and should only be handled using appropriate protective

measures. Please review this product’s Safety Data Sheet for a summary of such protective measures. These products are suitable only for and should only be sold for use by industrial or trade (commercial) professionals. These products are not suitable for Do-It-Yourself applications.

	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) [%]	80
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.

Storage and Transportation:

STORAGE: It is recommended to store in a dry and cool area with proper ventilation.

Packaging:

200KG/drum Please fasten the packaging cover as soon as possible after original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product. Do not inhale dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothes separately and reuse them after washing. Maintain good hygiene practices.
