Product Description

Nature Description

Hydroxyl value (mgKOH/g):225-255 acid value (mgKOH/g):≤ 0.05 moisture (%):≤ 0.10 PH:5-7 viscosity (mPa.s/25℃):200-400 potassium content K +(mg/kg):≤ 5 chroma (APHA):≤ 50 functionality 3 minutes: 700

Product Applications

Used for polyurethane elastomer crosslinking agent, rigid foam crosslinking agent and foam filler. Used for polyurethane elastomer cross-linking agent can increase the hardness of products; Used for hard foam cross-linking agent can reduce the viscosity of composite materials; Used for foam filler can increase the foam hardness and curing speed. It can be used for foam filler, MN-500 the effect of increasing the hardness of foam is more obvious, MN-1000 the effect of increasing the bonding strength is more obvious, and the performance of MN-700 is between the two.

Security

Storage conditions： When transporting MN-700, it should be strictly protected against rain and dirt, and be careful to handle it to prevent leakage caused by collision with hard objects. When storing MN-700, it should be stored at room temperature in a ventilated and dry warehouse to avoid being in a humid environment, and the storage temperature should be kept below 50℃, so as to avoid sun exposure, away from water sources, heat source. Or sealed storage in containers made of steel, aluminum, polyethylene or polypropylene. To prevent moisture absorption and oxidation, it is recommended to fill the containers with nitrogen. If the storage temperature is higher than 60℃, the product quality will decrease. Short-term heating or cooling has little effect on the quality of the product, but attention should be paid to the obvious increase in viscosity when the product is at a lower temperature, this situation may bring some difficulties to the production and processing process.
