Kukdo KD-293 is a high-flexibility modified solid bisphenol A epoxy resin in KD series, designed for flexibility needs of multi-scenario protective powder coatings. It is white solid particles with excellent anti-cracking, balanced mechanical strength and anti-deformation, strong adhesion to special-shaped substrates, ideal for multi-scenario industrial protective coating.
High-flexibility film formation - Film flexibility ≤1mm, excellent bending and anti-cracking performance, suitable for special-shaped parts
Modified molecular structure - Flexible segments introduced, balancing strength and toughness to adapt to substrate deformation
Excellent adhesion - 0-grade adhesion to special-shaped metal substrates, no risk of edge peeling
High-efficiency processing adaptation - Balanced melt flow, spraying without dead angles, uniform film formation
Wide scenario compatibility - Suitable for general protection, special-shaped part coating and other scenarios without 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
