Niax C-8

Overview:

N,N-dimethylcyclohexylamine is a low-viscosity, moderately active amine catalyst that can be used in a wide range of rigid foams. One of the main applications is the formulation of insulating foams, spray coatings, plates, plywood, on-site pouring and refrigeration. N,N-dimethylcyclohexylamine is also suitable for the manufacture of rigid foam furniture frames and decorative parts.

use:

This product 3 is especially suitable for the preparation of two-component systems. It can be dissolved in many rigid foam polyols and additives. In the combination, the performance is stable, no need to add organic tin, moderate activity, large adjustability, and long-term Store. Adding appropriate amount of LCA-1 and LCA-3 to the large-capacity refrigerator combination material can improve the foam flow performance. Generally, the amount of hard foam is about 3% of polyether, and auxiliary catalyst can also be added according to product requirements. This product has ammonia and bitter taste, has a stimulating effect on the skin, and has certain toxicity. It is necessary to wear protective equipment during production.

Dimethylcyclohexylamine DMCHA is a low-viscosity, moderately active amine catalyst used for refrigerator hard foams, plates, spray coating, and in-situ polyurethane hard foam infusion. DMCHA catalyst has a catalyst effect on both gel and foam. Dimethylcyclohexylamine provides a more balanced catalytic performance for the foaming reaction and gel reaction of hard foam. It has moderate catalytic activity for the reaction of water and isocyanate. DMCHA It is a strong initial catalyst for foam reaction. DMCHA can be used as a separate catalyst, but it is generally shared with other catalysts. According to the difference in reaction speed and foam properties, the amount of DMCHA per 100 parts of polyether polyol is between 0.5-3.5 parts. In addition to being used for hard foams, dimethylcyclohexylamine DMCHA can be used as an auxiliary catalyst for molding soft foams and semi-rigid foams.

In addition to being mainly used as a catalyst for rigid polyurethane foams, N-dimethylcyclohexylamine is also widely used in other aspects: it is also used as a fuel oil stabilizer to prevent the formation of oil residues; it is also a petroleum fraction at 150-480°C Stabilizing additives; also used as raw materials for medicines and pesticides, as bactericides, disinfectants, leveling agents and antistatic agents, etc.
