Stability/ thinnability:

DURANATETM TPA-90SB can be thinned with esters, ketones and aromatic.hydrocarbons such as ethyl acetate, butyl acetate, methoxypropylacetate(PMA), methylethyl ketone, methyl-butyl ketone, cyclohexanone, toluene, xylene, Solvesso #100 andmixture thereof. Generally speaking, it has good compatibility with the solventmentioned. However, the solutions formed must be tested for their storage stability.Only PU grade solvents can be used (max. 0.05% water, absence of reactive groupssuch as hydroxyl or amines groups). Aliphatic hydrocarbons such as hexane.cyclohexane, methylcyclohexanes and mineral spirits, are unsuitable as solventsbecause of their poor solubility.

DURANATETM TPA-90SB should not be thinned to below a solid content of 40%.Prolonged storage of solution with lower solid content may result in turbidity andsedimentation.

Compatibility：

Mixing ratio of DURANATETM TPA-90SB with polyols is based on NCO/OH equivalentratio of 1/1 .

Storage:

DURANATETM TPA-90SB is sensitive to moisture and should therefore always bestored in sealed containers.

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.
