Exceptional yellowing resistance under UV exposure and thermal aging, ideal for high-clarity and light-colored coatings.
Low-viscosity aliphatic isocyanate curing agent enabling excellent flow, leveling, and compatibility with common polyols.
Hydrolytically stable structure minimizes CO₂ formation and bubble defects during ambient or forced-dry curing.
Non-volatile, low-monomer-content formulation supporting VOC-compliant coating systems.
Consistent reactivity profile ensures reliable pot life control and full crosslink density development.
High-gloss automotive clearcoats requiring long-term color stability and weather resistance.
Premium architectural coatings for façades, windows, and aluminum composite panels (ACP).
Industrial wood finishes where clarity, hardness, and non-yellowing performance are critical.
Plastic coatings for outdoor signage, lighting housings, and consumer electronics enclosures.
UV-stable coil coatings for pre-finished metal used in building and appliance applications.
