Curing Agent · Anionic
YT-6300 is a waterborne anionic curing agent synthesised from aliphatic monomers. It has excellent anti-yellowing performance and can be mixed thoroughly with the resin by hand stirring; it serves as a crosslinker for most neutral waterborne polymers, giving coatings higher hardness, water resistance, chemical resistance and adhesion.

- Excellent anti-yellowing performance
- Increases hardness, water and chemical resistance and adhesion
- Crosslinker for most neutral waterborne polymers
- Coating systems requiring hardness, water and chemical resistance
Two-component use: excellent water dispersibility reduces the amount of organic solvent required and the product can even be used without thinning; the very high NCO content means a lower dosage than conventional curing agents; a 3–4 hour activation open time ensures the job can be completed. It can be thinned with non-hydroxyl solvents such as ketones, esters, glycol ethers and ether esters, but the water content of the thinning solvent must meet polyurethane grade.
Keep sealed and store in a cool, dry place for 6 months. Once the lid is opened, use the product as soon as possible.
