Can be diluted with esters, ketones, glycolether acetates or with aromatic hydrocarbons. Only urethane-grade solvents should be used to lessen the possibility of reacting with water.
If diluted to a polyisocyanate fraction of less than 40%, turbidity, flocculation, and/or sedimentation may occur during storage. Storage trials should always be conducted.
Solvents containing reactive groups (e.g. water. alcohols, amines) should not be used since they react with the PU hardener. It is recommended to use “urethane grade” solvent for the dilution (with water content below 500 ppm) , and ≥25% solid content after diluted is recommended.
The product is sensitive to moisture. Care should be taken to use or split charging to avoid the vapor. It must be sealed tight after use up as soon as possible.
The product should be kept in cool and dry place and no outdoors.
