Solubility :soluble in ethyl acetate, methylhexanone, methyl isobutyl ketone, methoxyhexanone, diacetone alcohol, 1-methoxypropyl acetate and 2-methoxybutyl acetate, However, the storage stability of the solution must be tested. Butyl acetate, as a single statistical trial, has only limited compatibility. Although PU-165 can be added with a certain proportion of aromatic hydrocarbon solvents, such as toluene or xylene as diluents, it cannot be dissolved in aromatic hydrocarbons and aliphatic hydrocarbon solvents, and polyurethane grade solvents should be used (water content <0.05%, no other reactive impurities) , PU-165 cannot be diluted to less than 30% solid content, low solid content of the base material will cause turbidity and flocculation.
Features Application: Double coating made of PU-165 and aliphatic isocyanate has excellent gloss retention and weather resistance, as well as excellent chemical resistance and abrasion resistance.
Storage: The product is stable for at least 6 months when stored in an airtight container below 30°C.
Safety: Flammable, harmful in contact with skin and inhalation, irritating to skin. Xylene and ethylbenzene are easy to cause harm to skin absorption, please try it carefully
