Incozol 2 – An effective Moisture Scavenger

Incozol 2 from Incorez is an oxazolidine that is supposed for use as an effective moisture scavenger in urethane coatings and sealants. It can also be employed to eradicate residual moisture from solvents, polyols and prepolymers and further from plasticizers and pigments.
Incozol 2 has a low toxicity rating and hydrolyses on exposure to moisture, yielding reactive hydroxyl and amine groups.
There are numerous advantages of this moisture scavenger that include:
• It eradicates CO2 bubbles and pinholes in two-component systems.
• It reduces down glossing and hazing under high humidity application conditions.
• It also improves gloss, abrasion resistance and chemical resistance.
• Prevents gassing and gelling in one-component moisture cure systems.
• Completely reacts into urethane polymer matrix.
• Outstanding handling properties.
Incozol 2 is perfect for use in one- or two-component systems. It is not usually recommended in one-component paints or sealants with a low NCO content as the residual amino alcohol reacts with the isocyanate during storage, during the reactivity of the entire system and resulting into retarded drying times.
