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 should be used (moisture content <0.05%)
features/applications
this product is a crosslinking agent for water-based paint. it is especially suitable for use in the civilian field where it can be mixed and used immediately after shaking or manual stirring.
even in the pre-diluted condition, the coating film is still transparent and bright. the mixing ratio of mill base to curing agent is usually 10:1.
