U-CAT SA 102 catalyst CAS112051-70-6 Sanyo Japan

Product Description

U-CAT SA 102 is a delayed acting polyurethane catalyst for use in two-component polyurethane systems, such as coatings, adhesives, and elastomers. It is a salt of DBU [1, 8-Diaza-bicyclo (5, 4, 0)undec-7-ene] with octanoic acid.

Physical and chemical properties

· CAS Number: 112051-70-6

· Molecular formula: C9H17N3O2

· Molecular weight: 189.25 g/mol

· Appearance: yellow liquid to solid

· Solubility: Easily soluble in water, polyols, butanone, ethyl acetate, etc.


U-CAT SA 102 is used to accelerate curing of two-component polyurethane systems. It is commonly added to the isocyanate component of the system. The amount of catalysis added will depend on the specific system being used.


· Delayed action: This allows for a longer application period at room temperature, which is important for applications where polyurethane must be applied and cured in a controlled manner.

· High catalytic activity: U-CAT SA 102 is effective even with aliphatic isocyanates, resulting in the formation of non-yellowing polyurethanes.

· Lower curing temperature: When used with a capped isocyanate, U-CAT SA 102 can lower the curing temperature, which can be beneficial in some applications.

· Increased coating speed: When used for wire coating, U-CAT SA 102 increases the coating speed.

Preventive measures

· U-CAT SA 102 is a skin irritant and respiratory irritant. It is also flammable.

· Always wear gloves, goggles, and a respirator when handling U-CAT SA 102.

· U-CAT SA 102 should be stored in a cool, dry place.

· U-CAT SA 102 should be disposed of in accordance with local regulations.
