Application

WANNATETM HB-75MX is an aromatic polyisocyanate based on toluene diisocyanate. It is a colorless or pale yellow liquid with a solvent-like odor. Approx. 75 % in ethyl acetate.

In combination with various hydroxyl-bearing substances to formulate two-component polyurethane coatings and adhesives.

Specification

Storage / Solubility

Storage in original container. Protect from moisture, heat and foreign material.WANNATETM HB-75MX is sensitive to moisture. Storage at higher temperatures will result in increasing of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely
affecting the quality of the product.
WANNATETM HB-75MX 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).
WANNATETM HB-75MX is not recommended to thin to a lower solid content.
Prolonged storage of a solution with a lower content may result in turbidity and sedimentation, even condensation.

Compatibility

WANNATETM HB-75MX can be mixed with the following products: aliphatic polyisocyanates,polyester polyols, aromatic polyisocyanates and polyacrylates.

Shelf Life

It can be stored at least for 9 months provided that the product is stored in full compliance with the storage conditions set forth in and referenced under section ” Storage / Solubility ”
above and is otherwise handled appropriately.
