Audited Supplier Electronic potting self-skinning combination material - HDPOL-52133/HDISO-7251E
Description
HDPOL-52133 is a self-skinning composite material that reacts with modified isocyanate HDISO-7251E to form high-resilience self-skinning foam products. It is suitable for manufacturing various cold-cured soft self-skinning products. It has a wide operating range and simple processing. The product has the characteristics of dense skin and small shrinkage rate.

Steps
1. Stir the polyol component HDPOL-52133 component evenly, add about 2%wt color paste into the barrel, and stir evenly again.
2. Add the uniformly stirred HDPOL-52133 into the component A tank, and add HDISO-7251E into the component B tank, and control the material temperature to 25°C. HDPOL-52133 is easy to stratify, please turn on the stirrer on the material tank.
3. Pour into the mold according to the ratio of HDPOL-52133/HDISO-7251E=100/20. Control the mold temperature to 45-50ºC.
4. Release the mold after 15 minutes.
Storage
Please store the product in a dry and cool place, away from direct sunlight and high heat. The product must be tightly closed immediately after opening to avoid water absorption. The shelf life of the product is 6 months.
Package
Packed in 200Kg or 20Kg iron drum or galvanized drum.
Precautions
Before using the product, the combined polyether HDPOL-52133 needs to be stirred evenly before it can be pumped into the machine; in the cold winter season (the temperature is below 0°C), the modified isocyanate HDISO-7251E needs to be stored in a greenhouse above 5°C. , to avoid crystallization causing the machine to be unable to produce; health and safety recommendations can be found in the safety instructions (MSDS) provided with this product data sheet.
