Product Description

Yl-W6100D is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate; it is used as a cross-linking agent component of waterborne two-component polyurethane system and as an additive to improve the performance of waterborne coatings.

Solubility

YL-W6100D can be diluted with esters, ether esters, xylene and solvent naphtha 100. Generally, it has good compatibility with the above solvents, but the stability of the prepared solution must be tested. Polyurethane grade solvents should be used (moisture content less than 0.05%, and the solvent should not contain active groups such as hydroxyl or amino groups).


Applications

Yl-W6100D is a cross-linking agent suitable for water-based system. It has moderate hydrophilicity and good flexibility, and can be emulsified and dispersed in water-based medium. The product is mainly used as crosslinking agent for waterborne polyols and crosslinking agent for most neutral aqueous polymer dispersions (such as polyurethane, polyvinyl acetate resin, polyacrylate and synthetic rubber dispersion).


After adding YL-W6100D, the two-component coating for use must be used during the activation period. The activation period is affected by polymer content and other components (e.g. resins, thickeners, plasticizers, etc.); in many dispersions, the end point of activation (usually several hours) does not show gelation.


Packaging and storage


Package specification

200L small mouth iron barrel, other packaging specifications can also be agreed

Storage

Please keep it away from light, cool and dry place. The storage temperature should be 5~30 ℃ to keep the package intact and sealed well. The shelf life of this product is 6 months from the date of production. It is recommended to evaluate the performance before use after more than 6 months.


Security


This product contains polyisocyanate, so you should be very careful when using it. Skin contact with this product may cause allergic reaction; all YL-W series products are very sensitive to moisture and react with water to form carbon dioxide and insoluble urea. Therefore, the packaging container must be well sealed to avoid reaction with moisture, solvent and moisture in the container. The carbon dioxide produced will increase the pressure of the container, thus increasing its risk.
