Versatile PU coating additives for 1K and 2K solvent borne and high solids

What is an Oxazolidine?

A versatile additive for both 1K and 2K solvent borne and high solids polyurethane systems.

Versatile PU coating additives


A five membered hetrocyclic ring structure containing nitrogen and oxygen.

It reacts with moisture to produce amine and alcohol groups which then react with isocyanates.

Oxazolidine Functions

  • Moisture scavenger
  • Latent curing agent
  • Reactive diluent

Oxazolidines offer great advantages in aliphatic PU systems

  • Fast curing with no evolution of carbon dioxide gas
  • Promote faster through cure in high build 1K systems
  • Accelerate the cure of low NCO prepolymers
  • Can be used to reduce VOC in high solids 2K systems

Incozol® 2

Incozol® 2 by Incorez acts as an effective moisture scavenger and drying agent based on mono-oxazolidine. It is ideal for use in two component aliphatic, clear polyurethane coatings and polyaspartic resins. Exhibits fast reactivity, low toxicity and low color. It shows low viscosity which makes the ...

Incozol® 4

Incozol® 4 by Incorez is bis-oxazolidine latent hardener for high-build coatings without carbon dioxide gassing. It hydrolyzes on exposure to moisture, yielding a reactive amine and hydroxyl functional crosslinking agent. Offers stability to repeated opening of containers and accelerates the curing ...

Incozol® EH

Incozol® EH by Incorez is urethane bis-oxazolidine-based latent hardener. It accelerates the cure of one component polyurethane coatings without the addition of metal catalysts. It enhances properties such as mechanical strength through the elimination of carbon dioxide gassing in high-build, high-s...

Incozol® LV

Incozol® LV by Incorez is a low viscosity latent hardener and reactive diluent based on bis-oxazolidine. It can be used as a bi- or tetra-functional curing agent, enabling greater formulation flexibility. It hydrolysis on exposure to moisture, yielding a reactive amine and hydroxyl functional cross-...
