Painting

K-Form provides multiple paint options including wet paint and powder coat.

Industrial Liquid Painting – Polane

Polane is a two component coating consisting of polyurethane enamel and a catalyst. After paint preparation such as iriditng or phospating, paint is applied using an electrostatic gun. Electrostatics is based on the principle that bodies with unlike charges (negative/positive) attract. Atomized negatively charged paint particles are attracted to the positively charged object being coated. The paint is then either cured in ambient air for 24 hours or force dried in an oven for 30 minutes at 140-190 degrees F. The result is a low gloss coating which provides a superior appearance and durable finish.

Polane Advantages

  • Versatile over many surfaces – metal, plastics, and wood
  • Air dry or heat dry
  • Excellent adhesion, mar, and abrasion resistance
  • Excellent hardness and impact resistance
  • Resistant to stains, chemicals, and water
  • Texturing minimizes surface irregularities
  • Full color range through custom mixing
  • Free of lead and chromate hazards
  • Interior and Exterior usage

Powder Coat Painting

Powder coating is the application of finely ground particles of pigment and resin using an electrostatic method. An electrostatic gun gives the particles a negative electrical charge. The object being coated is grounded (or, in some cases given a positive charge. The difference in charge causes a strong attraction and the powder adheres to surface of object – similar to the function of a copy machine or laser printer. The applied powder is then heated (cured) in an oven to its melting point, typically 375-400 degrees F for 15-20 minutes. During the curing process the particles flow to form a smooth film which dries to a firm, durable finish very resistant to scratches, cracking, peeling, UV rays and rust.

Powder coat Advantages

  • Color unlimited – high and low gloss, metallic, and clear finishes
  • Protective of environment – no volatile organic compounds (VOC) as in liquid paints
  • Powder coat overspray can be retrieved and reused – eliminating waste found in liquid finishing processes.
  • Durable, abrasion resistant
  • Resistant to fading, peeling, and chipping
  • Cures quickly
  • Lower temperatures cures allow application to surfaces such as wood, ceramics, and plastics
  • Interior and exterior usage

Benefits of powder coating vs. liquid coating

  • Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes
  • Lower film thickness has a superior performance to higher wet film thickness
  • Powder coating meets or exceeds the corrosion resistance of a comparable liquid coating system
  • General performance properties, impact resistance and corrosion resistance of powder coating are better than liquid paints
  • Powder coating process is up to 50% more energy efficient than the liquid coating process
  • Liquid paints often contain solvents, which can contribute to air pollution releasing volatile organic compound (VOC). Powder coat does not contain any solvents and only releases negligible amounts of VOCs into the atmosphere, resulting in no air pollution
  • Powder coating overspray can be retrieved and reused
  • Wet painting processes generate sludge, which must be disposed of into hazardous waste landfills
