Polyurethane Powder Coatings

IFS polyurethane powder coatings exhibit properties similar to epoxy powders, but also offer exterior durability and are often more ‘overbake stable’ than epoxies (though not as good as Polyester TGIC powders).

Disadvantages include a more restricted cure range, potential odor and smoke from cure, and significantly higher cost.

Polyurethanes are most commonly found in exterior functional applications where chemical exposure is a concern

IFS polyurethane advantages include:

  • excellent adhesion 6 piles of colored powder
  • excellent chemical resistance
  • excellent corrosion resistance
  • excellent flexibility
  • excellent hardness
  • good exterior durability

Their disadvantages can be summarized as follows:

  • restricted cure range - tight application and cure parameters
  • odor on application/cure
  • smoke created during cure
  • cost

IFS polyurethane powders can also be custom formulated.

Please note that these represent general guidelines. Talk to the IFS lab or representative for a more detailed explanation and specific uses.
