TOCPOLY NH-322 curing agent is specially developed for polyisocyanate resins. It is optimally matched with standard and low-viscosity HDI trimer isocyanates for a wide range of industrial applications. This curing agent delivers flexible formulation design for both high-gloss and matte coatings. Clear coats and pigmented topcoats formulated with TOCPOLY NH-322 feature outstanding aesthetic appearance and superior UV durability.
It is recommended to use coatings based on TOCPOLY NH-322 together with solvent-free epoxy primers. Pot life and drying time will be significantly shortened under high-humidity conditions.
Product Features
· Low mixed viscosity for easy handling
· Fast curing speed with excellent surface finish
· Produces high-gloss topcoat finishes
· Suitable for trowel application; single-coat film thickness up to 500 μm
