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.

After inhalation, it can be fatal due to spasm, inflammation, edema, chemical pneumonia or pulmonary edema of the larynx and bronchus. Burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting after exposure.
- Toxicological data and environmental behavior Acute toxicity: LD50 348mg/kg (rat oral); LC501889mg/m3 2 hours (rat inhalation)
It is flammable in case of fire and high heat. It can react with oxidants. In case of high heat, the internal pressure of the container increases and there is a risk of cracking and explosion. Combustion (decomposition) products: carbon monoxide, carbon dioxide, nitrogen oxide.
180KG/drum 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 water and other substances from mixing into the product and affecting its performance. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits.
