Properties and stability

It is flammable and has an ammonia odor.

This product has low toxicity. Its vapor is irritating to the skin. Operators should wear protective equipment. After contact with skin, rinse with water. For protection, refer to general amine compounds.

Storage method

This product should be kept sealed.

Packaged in galvanized iron barrels, net weight per barrel is 50kg, 100kg, 200kg. Store in a cool, dry and ventilated place. Store and transport according to general flammable chemical regulations. It cannot be mixed with acidic, edible and other chemical products, and should be sealed and stored to prevent moisture absorption.

Synthesis method

Add phenol and 40% dimethylamine aqueous solution to the reaction kettle, stir and mix evenly, cool to below 20°C, slowly add 30% formaldehyde aqueous solution while stirring, and control to complete the addition below 30°C. Continue stirring at 25-30°C for 1 hour, then raise the temperature to 90-95°C and reflux for 2 hours. Add salt to separate the water phase, and separate the oil layer for fractionation under reduced pressure to obtain the finished product. Industrial product content is over 95%.


This catalyst is a polyisocyanurate (PIR) reaction catalyst. Its catalytic selectivity for PIR reaction is higher than that of PUR, so it is mostly used in the formulation of polyisocyanurate reaction. Its characteristics can help the foaming rising curve become regular and have good fluidity. It is suitable for the injection molding reaction of polyisocyanurate. This product is a weakly active catalyst and is used in large amounts in the formula. It has mild reaction, stable rise, and good fluidity. The obtained products have PIR high temperature resistance and flame resistance effects. Can be used to prepare combination materials. This product is used as a curing agent and accelerator for epoxy resin. Its molecular structure contains phenolic hydroxyl groups, which increases its activity and can be used for rapid curing. However, it has a short service life and is mainly used for adhesives. This product can be used as an accelerator for acid anhydride curing agents in cast and laminated products. The amount used as a curing agent is generally 10 parts, and the amount used as an accelerator is generally 0.1 to 3 parts. Applicable curing agents: amines, acid anhydrides, low molecular weight polyamide curing agents. Used as an antioxidant and also used in dye preparation. Used as a curing agent for thermosetting epoxy resin and a curing accelerator for other resins, as well as a curing agent for ship bottom coatings and architectural coatings, the reference dosage is 0.1 to 3 parts (mass parts ). Also used as sealant, adhesive, acid neutralizer for laminate materials and flooring. Used as a catalyst in the synthesis of polyurethane.
