The Durafine Advantage

Durafine Coatings is a “full service” manufacturer of water-borne industrial coatings. We also custom-manufacture coatings to your requirements, including color matching.

High-Performance PVC & uPVC Coatings for Industrial Applications

PVC profiles, doors, windows, trims, and architectural components require coatings that do much more than add colour. They must withstand prolonged UV exposure, resist weathering, maintain gloss, and deliver excellent adhesion to one of the most challenging plastic substrates. Durafine's waterborne PVC coating systems are engineered specifically for manufacturers looking for long-lasting decorative and protective finishes. Whether you're coating PVC doors, uPVC window profiles, wall panels, or other extrusion products, our coatings combine outstanding appearance with industrial-grade durability.

Why PVC Manufacturers Choose Durafine Coatings?

PVC is naturally difficult to coat due to its low surface. Without the right formulation, coatings can peel, crack, fade, or lose adhesion over time. Durafine develops advanced coating systems that overcome these challenges while improving manufacturing efficiency and product performance. Our coatings are suitable for both new production lines and existing finishing operations.

Durafine's coating technology is formulated to provide reliable performance throughout the product lifecycle.

- Excellent Adhesion: Engineered for strong bonding on properly prepared PVC and uPVC substrates.
- Superior Weather Resistance: Designed to resist sunlight, moisture, and outdoor environmental conditions.
- Outstanding UV Stability: Maintains colour consistency and gloss even after prolonged exterior exposure.
- Smooth Decorative Finish: Produces premium matte, satin, or gloss finishes with excellent flow and leveling.
- Heat Reflective Technology: Available with IR-reflective pigments that reduce heat build-up in dark coloured profiles.
- Faster Production: Easy spray application with air-dry or low-temperature oven-curing options.
- Custom Colour Matching: Available in virtually any RAL, Pantone, or custom shade to match your product range.
- Environmentally Responsible: Waterborne, low-VOC formulations that support sustainable manufacturing practices.

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
