Product Description

Nature Description

Hydroxyl value (mgKOH/g):440-460 acid value (mgKOH/g):≤ 0.08 moisture (%):≤ 0.08 PH:5-8 viscosity (mPa.s/25℃):300-500 potassium content K +(mg/kg):≤ 8 chroma (APHA):≤ 50 functionality: 3 minutes: 375

Product Applications

Used for polyurethane elastomer crosslinking agent, rigid foam crosslinking agent and foam filler. Used for polyurethane elastomer and semi-rigid foam cross-linking agent, which can increase the hardness of products; Used for rigid foam cross-linking agent can reduce the viscosity of composite materials; Used for foam filler can increase the foam hardness and curing speed.

Security

Storage conditions： When transporting DV-125, 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 DV-125, 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.
