Incozol™ EH

1 of 5 products in this brand
Incozol™ EH is a urethane bis-oxazolidine latent hardener designed for use in one-component polyurethane coatings, adhesives, sealants, and elastomers. It accelerates curing in low NCO prepolymers via a moisture-triggered mechanism, enabling crosslinking and enhancing properties such as cure development and mechanical strength. It eliminates CO2 gassing in high-build, high-solids systems, offers tolerance to repeated container openings, and supports versatile curing with two- or four-functional mix ratios. It can be stored and handled at temperatures as low as -15°C without crystallization.

High Tensile Strength,
In-Can Stability,
Low Volatility
Key Features
  • Can be stored at sub-zero temperatures (down to -15oC) without signs of crystallisation, making handling and storage easier and more convenient than other types of bis-oxazolidines.
  • Excellent in-can stability for 1-K aliphatic and aromatic PU systems.
  • Increased through-cure and tensile profile of formulated PU system leading to tougher, more durable product.
  • Reduced odour – the reduced volatility of the aldehyde leaving group (2-ethyl hexanal) in this product results in less pungent odour than bis-oxazolidines based on isobutyraldehyde. Useful for low odour 1-K PU formulations.

Applications & Uses

Compatible Polymers & Resins
Polyurethanes (PU)
Adhesive & Sealant End Applications
1K (1 Component) Adhesive,
1K (1 Component) Sealant
Coating End Applications
1K (1 component) Coating,
Polyurethane Coating
Key Applications
  • To improve the aesthetics and performance of PU systems, by eliminating CO2 gas formation.
  • To increase cure speed of a 1-K PU systems where the addition of metal based catalysts are restricted or unwanted.
  • Incozol EH is particularly suited for use in aromatic 1-K PU systems where in-can stability may be an issue.
