PROCESSING TEMPERATURE
To achieve the best result, it is suggested to pre-heat the product for 2-3 hours under 80~90℃, in a hot air circulatory or vacuum dryer.
USAGE
Add 30% TR-1172 in 70% DMF or the other solvents, stirring with high speed mixer until all TPU particles dissolve in the solvent. You can adjust the viscosity by adding some solvent in the solution according to your requirements.
