2-Hydroxy-N,N,N-trimethyl-1-propylamine formate It is a tertiary amine catalyst, used to promote polyisocyanurate reaction (trimerization reaction); 2-hydroxy-N,N,N-trimethyl-1-propylamine formateCompared with potassium catalysts, it can uniformly control the starting reaction.

Product usage:

TMR-2 is a tertiary amine catalyst used to promote the polyisocyanurate reaction (trimerization reaction). Compared with potassium catalysts, it can evenly control the onset reaction;

TMR-2 catalyst is used in rigid foam applications. Compared with TMR catalyst, it provides better fluidity. It can also be used in flexible molded foam applications. After curing.

TMR-2 is used for polyisocyanurate (PIR), but the reaction is milder, which can shorten the demolding time of rigid foam; mainly used for polyurethane rigid Quality foam, such as board, refrigerator combination material, etc. TMR-2 catalyst is a kind of quaternary ammonium salt catalyst, mainly used to make polyurethane rigid foam. It can improve the mechanical and technological properties of the foam, shorten the curing time of the foam, reduce the residual content of -NCO in the foam, and improve the overall performance of the foam. Features.

TMR-2 is a quaternary ammonium salt catalyst with low dosage. The amount of catalyst is 1%-5% of isocyanate. It can be used in various rigid foam systems such as polyurethane and polyisocyanate. An isocyanurate ring is formed above 20°C and serves as a high-temperature catalyst. Good miscibility with isocyanate and other raw materials.

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse.

Packaging:

180KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade.
