IFS Polyurethanes

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

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 powder piles
  • 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 polyurethanes can 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.
