Application Guidelines

1. ZC-698WD resin does not contain wax, accelerators, or thixotropes.
2. In order to ensure compliance with the requirements of GB13115-1991 standard, the dosage of accelerators and curing agents used in the production of food grade fiberglass products should meet the following requirements: tertiary amine: ≤ 0.1% cobalt octanoate or cobalt cyclohexane: ≤ 0.03% peroxide: ≤ 3.0%
3. In order to ensure compliance with the requirements of GB13115-1991 standard, the post curing treatment of food grade fiberglass products is as follows: curing at 80 ° C for 3-4 hours, and cleaning with hot water at 80 ° C for 1-2 hours.
4. It is recommended to choose NEWSOLAR9365 resin for the structural layer of wrapped pipelines and storage tanks.
