PF Resin Powder For Cooling Pad in Dipping Process

Cooling pad PF Resin Powder is Phenol-Formaldehyde (PF) Resin Powder. It must be dissolved in water prior to use and provides a good water and moisture resistance in dipping process.

DISSOLVING THE RESIN:

Prior to use, the resin is mixed with water to convert into solution. A mechanical stirrer may be used for this purpose. With high speed mixer all the water may be placed first and then resin may be added, while mixer is running.If low speed mixer is used, it is better to make a homogenous mix of the resin with about 1/2 of water, and rest of the water may be added later.

The temperature of the water may be 20～30℃, because with lower water temperature, mixing is time consuming. Reconstitution can be carried out in simple mixing equipment as follows:

1. Take all the water in the mixer. The water temperature should not be below 200C

2. Add required amount of resin powder and mix until a homogenous solution is obtained.

3. Once a homogenous solution has been obtained, other additives and hardener will be added.

TECHNICAL SPECIFICATIONS:

STORAGE

The powder resin should be stored in the original bags in a cool place protected from heat. When stored at high temperature, the storage stability will impair considerably. Care should be taken that powder does not absorb moisture and water.

The bags, which have been opened, should be carefully closed before storage. When stored in original bags at 20°C shelf life would be not less than one year.
