Powder Coating
Non-Metal Surfaces

Historically, powder coating was limited to metal substrates. IFS PureClad changes that by solving the technical challenges that prevented powder from being used on wood, MDF, and other heat-sensitive materials.

Historical Barriers

Key Technical Challenges

Significant R&D investment went into solving five core problems that had prevented powder from being a viable finish for wood-based substrates.

  • Low-Temperature Cure

    Achieving a full cure without damaging heat-sensitive materials like MDF or hardwood. PureClad cures at 265°F in a catalytic IR oven.

  • Moisture in MDF

    MDF moisture content causes outgassing during cure, creating surface defects. PureClad formulations are engineered to mitigate these effects.

  • Uniform Application

    Non-conductive surfaces resist the electrostatic charge needed to attract powder. Specialized application techniques ensure a consistent, even film build.

  • Flexibility

    Wood-based materials expand and contract with humidity and temperature. The coating must accommodate this movement without cracking or delaminating.

  • Community Alignment

    Delivering a robust solution requires collaboration between raw material suppliers, equipment manufacturers, and applicators to align on process standards.

Advantages Over Incumbent Technologies

IFS PureClad addresses the specific weaknesses of three dominant alternatives, delivering superior performance with a better environmental profile.

Incumbent

vs. Thermofoil

Advantages

  • Enhanced UV durability and color retention
  • No delamination risk after cure
  • Wide array of finishes and effects

Limitations

  • Poor UV and heat resistance
  • Prone to delamination over time
  • Environmental and disposal concerns

Incumbent

vs. Laminate

Advantages

  • Superior chemical and stain resistance
  • Long-term durability
  • Recyclable and lower environmental impact

Limitations

  • Susceptible to cracking and peeling
  • Short service life in wet environments
  • Non-recyclable materials

Incumbent

vs. Liquid Paint

Advantages

  • Negligible VOC emissions from a solvent-free process
  • Up to 97% material utilisation
  • Fast single-coat cure in ~10 minutes

Limitations

  • High VOC emissions
  • Low material utilisation rate
  • Lengthy multi-coat curing process

The Solution

IFS PureClad

IFS PureClad is an industry-changing line of powder coatings engineered specifically for heat-sensitive substrates. It delivers tough, durable protection with endless customisation options, including colors, textures, and gloss levels, while remaining environmentally responsible.

Unlike traditional low-cure chemistry, PureClad doesn't require compromising on production speed, efficiency, or technical performance. Cure takes as little as 6 minutes at 265°F in a gas catalytic IR oven.

Full PureClad overview
01

265°F Cure Temperature

Low enough for standard MDF and many natural wood materials without damaging the substrate.

02

~10-Minute Process

Coating and curing combined. An extremely favourable comparison to multi-coat liquid paint systems.

03

Negligible VOC Emissions

No solvents, no hazardous waste, and no toxic landfill make this an inherently cleaner process.
