solubility/dilution
bayhydur 305 generally has good compatibility with organic solvents such as esters, ether esters, xylene and solvent naphtha 100. however, in any case, the solubility/miscibility of the prepared solution must be tested. polyurethane grade solvents (moisture content <0.05%) should be used
features/applications
this product is a cross-linking agent for water-based coatings. it is particularly suitable for use in civil fields where it can be mixed and used immediately after vibration or manual stirring.
even under pre-diluted conditions, the coating is still transparent and bright. the mixing ratio of grinding base to curing agent is usually 10:1.
