Preston, UK -- Incorez, a global manufacturer of specialist resins and polymers, has launched a new bis-oxazolidine latent curing agent, Incozol EH - for use in one-component (1K) polyurethane coatings, adhesives, sealants and elastomers.
The product's properties mean that Incozol EH can be stored at sub-zero temperatures (as low as -15°C) without crystallising, making handling and storage easier and more convenient than other types of bis-oxazolidine, Incorez said in a 30 Jan news release.
The reduced volatility of the aldehyde leaving group in Incozol EH results in a less pungent odour than bis-oxazolidines based on isobutyraldehyde, making it particularly useful for low-odour 1K PU formulations. The product also possesses excellent in-can stability for both 1K aliphatic and aromatic PU systems, according to the company.
"Incozol EH is an exciting addition to the current bis-oxazolidine market and is capable of increasing the cure speed of 1K PU systems without the need for metal catalysts," commented Ian Williams, marketing manager at Incorez.
"As the product can be stored at lower temperatures without crystallising, this helps to lower handling costs and allows them to be less focused on the stock being affected by weather conditions," he added.
Incorez said the product's typical applications include flooring & balcony systems, roof coatings and sealants.
