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
