Our high performance Incozol® additives bring exceptional levels of performance to polyurethane coatings, adhesives and sealants.

These advanced oxazolidines speed up curing and prevent the generation of CO2. This eliminates bubbling on application to help preserve aesthetics and minimise pinhole defects, giving you a better finish and improved film integrity.
Our moisture triggered chemistry enables curing in all kinds of temperature and humidity conditions resulting in tougher, more durable films. This makes the Incozol® range suitable for even the most challenging of applications.

Incozol 2
- Low toxicity, mono-oxazolidine moisture scavenger and drying agent.
- Fast reacting - hydrolyses on exposure to moisture.
- Low colour and low viscosity.
- Eliminates CO2 bubbles and pinholes in two-component systems.
- Minimises downglossing and hazing under high humidity application conditions.
- Fully reacts into urethane polymer matrix.
- Confers tolerance to repeated opening of containers.
- Removal of water from polyols in two component polyurethanes
- Removal of water from solvents, plasticisers and pigment pastes
- Prevents gassing and gelling in one-component systems
- Humidity control during application of sprayed polyurethanes

Incozol EH
- A bis-oxazolidine latent hardener for use in 1K polyurethane coatings, adhesives, sealants and elastomers.
- Can be stored at sub-zero temperatures (down to -15°C) without signs of crystallisation, making handling and storage easier and more convenient than other types of bis-oxazolidine.
- Excellent in-can stability for 1K aliphatic and aromatic PU systems.
- Reduced odour - the reduced volatility of the aldehyde leaving group (2-ethyl hexanal) in this product results in a less pungent odour than bis-oxazolidines based on isobutyraldehyde. Useful for low odour 1K PU formulations.
- Flooring & Balcony Systems
- Roof Coatings
- Sealants
- Increases cure speed of 1K PU systems without the need for metal catalysts
- Aromatic 1K PU systems where in-can stability may be an issue
