Stability / thinnability:

DURANATETM 22A-75PX can be thinned with esters, ketones and aromatic.hydrocarbons such as ethyl acetate, butyl acetate, methoxypropylacetate (PMA),methyl ethyl ketone, methyl-butyl ketone, cyclohexanone, toluene, xylene, Solvesso#100 and mixture thereof. Generally speaking, it has good compatibility with thesolvents mentioned. However, the solutions formed must be tested for their storagestability.

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 22A-75PX 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 22A-75PX with polyols is based on NCO/OH equivalentratio of 1/1 .

Storage:

DURANATETM 22A-75PX is sensitive to moisture and should therefore always bestored in sealed containers.
