Kukdo KD-293U is a UV-resistant modified solid bisphenol A epoxy resin in KD series, designed for long-term weather resistance of outdoor functional powder coatings. It is off-white solid particles with excellent anti-yellowing, good weather resistance and mechanical strength, long-lasting substrate adhesion, ideal for outdoor long-term protective coating.
Excellent UV resistance - UV aging resistance ≥3000h, outstanding anti-yellowing and anti-chalking performance for outdoor use
Modified weather-resistant structure - Weather-resistant groups introduced in molecular structure, long-term effective film protection
Balanced mechanical properties - Balanced impact and bending resistance, adapting to outdoor environmental stress changes
Long-term adhesion - Adhesion to outdoor metal substrates does not attenuate for ≥5 years, lasting protection
Wide system compatibility - Good adaptability with weather-resistant curing agents, pigments and fillers, flexible formula adjustment
Outdoor building material coating - Weather-resistant protective coating for aluminum profiles, color steel plates and other outdoor building materials
New energy facility coatings - Outdoor UV-resistant protective coating for photovoltaic brackets and wind power accessories
Traffic facility coatings - Long-term weather-resistant protective coating for highway guardrails and signboards
Garden facility coatings - Anti-yellowing decorative protective coating for outdoor garden metal facilities
Communication facility coatings - Outdoor weather-resistant coating for communication base station enclosures and signal tower accessories
