Water-based curing agent YL-W6907

【 Product Description 】YL-W6907 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate and isophorone diisocyanate. It is used as hardener component in aqueous two-component polyurethane coating system.
[Product Characteristics] A crosslinking agent suitable for water-based systems, because of its hydrophilic properties, and has been diluted with PMA and a small amount of xylene, so in the water phase, even in the case of commercial shear forces, it is easy to disperse emulsification.
[Application] Floor, runway, wood paint, industrial paint
【 Packaging Specifications 】20L or 60L small lipstick body iron drum, other packaging specifications can be agreed.

Instructions for use

The addition of YL-W6907 to the two-component aqueous polyurethane system has a long activation period, a fast hardness establishment rate and excellent chemical or solvent resistance. 2/2 Although the addition of YL-W6907 has a long activation period of the two-component coating, the activation period is affected by the polymer content and other components (such as resins, thickeners, plasticizers, etc.); In many dispersions, the end point of the activation period (usually a few hours) does not show up as gelation.
