Powder Application Technique

Typical range: 2-3 mils (50-75 microns) dry film thickness. Thicker coating (3-4 mils) provides better durability but increases cost and cure time. Thinner coating (<2 mils) risks poor adhesion and durability. Measure with micrometer or thickness gauge for consistency.

Granular texture usually indicates: substrate too warm (powder melts unevenly), insufficient electrostatic charge (increase voltage 5-10 kV), or humidity too high during spray. Reduce substrate temperature, verify equipment calibration, and maintain humidity below 50%.

Yes, but use thin coating (1.5-2 mils) to preserve design clarity. Clear matte or gloss powders work best. Colored powders may tint the design. Test on proof piece first. Ensure print is fully cured before powder application.

Test: tape pull test. If coating lifts, causes: inadequate substrate prep (oil/dust), insufficient pre-bake, low electrostatic charge, or incompatible substrate. Solutions: wipe substrate with alcohol, increase pre-bake temp/time, increase spray voltage, or use primer for difficult substrates.

UV-cure: 3-5 minute cure, lower energy cost, ideal for high volume. Thermal-cure: 10-20 minute cure, requires oven, more durable finish. UV is faster; thermal gives superior durability for heavy-use products. Choose based on your production volume and durability needs.

Properly applied and cured: 3-5+ years in typical use, 5-10+ years in indoor conditions. Outdoor exposure (UV, moisture) degrades faster. Durability depends on substrate quality, coating thickness, cure method, and user care. UV-cured is more resistant to yellowing than thermal-cure clear coatings.
