Phenolic resin for foundry
This series is thermoplastic phenolic resin with yellow flakes or grannulars, characterized in as follows:
1. The resin has high strength and the amount of addition is small, which can reduce the cost.
2. Low gas generation, reduce casting porosity defects and improve yield.
3. The resin has good flowability, easy filming, and filling without any dead angle.
4. Low free phenol, reduce environmental pollution and improve the working environment of workers.
5. Fastening speed, improve core shooting efficiency and reduce working hours.

Packing and storage
Package: flake/granular: 25kg/40 kg per bag, Packed in woven bag, or in Kraft paper bag with plastic liner inside. Resin should be stored in a cool, dry and well ventilated place far away from heat
Application
Phenolic resin special for foundry coated sand, mainly used for solid core and shell in the production of coated sand. It has the characteristics of high strength and low free phenol content
Instructions
3.1 Sand selection. When using, first select the particle size of the raw sand according to the requirements.
3.2 Fried sand. After selecting the particle size, weigh a certain weight of raw sand for frying.
3.3 Add phenolic resin. After the temperature reaches 130-150℃, add phenolic resin.
3.4 Gauto water solution. The amount of Utopia added is 12-20% of the resin addition.
3.5 Add calcium stearate.
3.6 Perform sand removal, crushing, screening, cooling, and storage.
4. Matters needing attention:
The resin must be stored in a ventilated and dry place. Avoid direct sunlight and keep away from heat sources. The storage temperature should not exceed 35°C. Do not stack the resin bag too high during storage. Tie the mouth immediately after use to avoid agglomeration.
