Application

The product 3, especially suitable for the preparation of two-component system, can be dissolved in many hard foam polyol and auxiliaries, in the combination of materials, stable performance, no need to add organotin, moderate activity, adjustability, and can be stored for a long time. In the large-capacity refrigerator combination material, add the appropriate amount of LCA-1, LCA-3, it can improve the flow performance of the foam. The general dosage of hard foam is about 3% of polyether, and auxiliary catalyst can also be added according to the requirements of products. The product has ammonia flavor and bitter taste, irritation to the skin, a certain degree of toxicity, the production must wear good protective equipment.

Dimethylcyclohexylamine DMCHA is a low viscosity medium active amine catalyst, used for refrigerator hard foam, sheet, spraying, on-site filling polyurethane hard foam.DMCHA catalyst has catalytic effect on both gel and foam, Dimethylcyclohexylamine provides balanced catalytic performance for foam and gel reaction of hard foam, and it has moderate catalytic property for the reaction between water and isocyanate, DMCHA is a strong initial catalyst for foam reaction. DMCHA can be used as a stand-alone catalyst, but it is generally used together with other catalysts. Depending on the reaction rate and foam properties, the amount of DMCHA per 100 parts of polyether polyol ranges from 0.5 to 3.5 parts. In addition to hard foam, N-Dimethylcyclohexylamine DMCHA can be used as auxiliary catalyst for molding soft foam and semi-hard foam.

N-Dimethylcyclohexylamine DMCHA is mainly used as the catalyst for rigid polyurethane foam, but also has a wide range of other uses: it is also used as a stabilizer for fuel oil to prevent the formation of oil residue; at the same time, it is also a stabilizing additive for the petroleum distillate of 150-480 ℃; and it is also used as the raw material for pharmaceuticals and pesticides as a biocide, a disinfectant, an equalizing agent, and an antistatic agent, and so on.
