Product Description: Easy to meter standard polyurethane foaming catalyst Niax A-133
Description: Niax A-133 is a standardized foaming catalyst for polyurethane.
Niax catalyst A-133 is a low concentration of bis(2-dimethylaminoethyl) ether, one of the most active polyurethane foam amine catalysts known. For convenience, Niax Catalyst A-133 consists of the pure amine ether BDMAEE diluted with dipropylene glycol monohydrate for ease of dosing and to allow for the use of conventional amounts in foam formulations.
Niax Catalyst A-133 can be used over a wide range with gel catalysts Niax A-33 or stannous octoate to control foam rise time without affecting the tin operating range.
