Water-based curing agent YL-W6500

【 Product Description 】YL-W6500 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate; It can be used as hardener in aqueous two-component polyurethane system.
[Product features] Crosslinker suitable for water-based system; Although the hydrophilicity of the curing agent is relatively weak, in the water phase, due to the extremely low viscosity of the product, it is extremely easy to emulsify and disperse under the condition of low shear force commonly seen in commercial use. The coating prepared by using this product has good extinction and physical and chemical properties, so it is recommended to use this product in semi-light or matte water-based coating system.
[Application] Floor, runway, wood paint, industrial paint
【 Packaging Specifications 】20L or 60L small mouth blue body iron drum, other packaging specifications can be agreed.

Instructions for use

L-W6500 can also be used as a crosslinking agent for water-based polyols and most neutral hydroxy free water-based polymer dispersions (such as polyurethanes, polyvinyl acetate resins, polyacrylates and synthetic rubber dispersions) to improve their performance in all aspects. 2/2 After the addition of YL-W6500, the two-component paint to be used must be used during the activation period. The activation period is affected by the polymer content and other components (e.g. resins, thickeners, plasticizers, etc.), and in many dispersions, the end point of the activation period (usually several hours) does not show up as a gel phenomenon.
