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.
