In the phenolic urethane cold box process, amines are vaporized to act as the catalyst which initiates reaction between a phenolic resin and an isocyanate resin, to form a urethane polymer. TEA (triethylamine), DMEA (dimethylethylamine), and DMIPA (dimethylisopropylamine) are used in the vapor form as catalysts in this process. HA International offers these materials for use with our Sigma Cure line of phenolic urethane cold box resins.

Health & Safety Information:

Fire, equipment damage, and personnel exposure may occur if Part 1 and 2 components are mixed together without adequate sand to absorb the heat of the resulting reaction. Ensure your facility has good labeling, safety procedures, and training to prevent inadvertent mixing, and specifically unloading mistakes. Emergency plans should address inadvertent resin mixing if these products are handled in bulk quantities. Customers must develop and deploy appropriate engineering controls, procedures, and/or PPE to prevent exposure above applicable criteria and/or personnel injury. Personnel handling these products must receive hazard communication training.

PUCB Part 2 resins are formulated with MDI, which in rare cases may cause sensitization (allergic reaction) among exposed workers. These products should never be sprayed or heated during use. Medical monitoring programs are recommended for personnel working in areas where these products are handled. Customers must develop effective procedures to prevent skin exposure to liquid products and provide employee training on hazard recognition, hazard management, and proper response to exposure incidents.

PUCB Catalysts are flammable and corrosive. Customers must employ appropriate procedures and personnel training to prevent fire, explosion and personnel exposure. Personnel must be trained to properly respond to exposure incidents, particularly incidents involving eye exposure.

Carefully review the MSDS for safety information that may be relevant to your operations. Develop the means to manage product hazards before ordering. Contact our product safety group if you require assistance in understanding or managing these issues.
