Stability / thinnability:
DURANATETM TPA-100 can be thinned with esters,
ketones and aromatichydrocarbons 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 thesolventmentioned. 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-100 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-100 with polyols is based on NCO/OH equivalentratio of 1/1.
Storage:
DURANATETM TPA-100 is sensitive to moisture and should therefore always be storedin sealed containers.
