Durafine Case Study
IR-Reflective Coatings for uPVC Profiles
Problem In high-temperature climates (e.g., the Middle East, India, Southeast Asia), dark-colored uPVC components absorb solar heat, leading to:
Thermal warping and expansion
Premature material degradation
Color fading and gloss loss
Rejection rates and warranty issues
Durafine identified this pain point and partnered with uPVC profile manufacturers to develop an Infrared (IR)-Reflective Coating that allows even dark shades to perform well under harsh sun exposure.
Challenge
Client needed:
Exterior-grade coating for uPVC profiles in dark colors (black, brown, anthracite grey)
High solar reflectance, especially in the NIR (Near Infrared) range
Strong adhesion to uPVC (a low-energy substrate)
Long-term UV, heat, and water resistance
Spray, roller, or dip application compatibility
Low VOC and environmentally compliant
