ACO Drain channel bodies are highly resistant to chemical attack and, with the appropriate grate, can be used in most environments where acids and dilute alkalis are encountered.

Refer to chemical chart for resistance of Polyester and Vinyl ester polymer concrete. FlowDrain products use the same polyester resin - refer to Polyester details for chemical resistance.

When greater chemical resistance is required, Vinyl ester polymer concrete channels should be specified.

These recommendations are for guidance only. Customers are advised to test a coupon of polymer concrete to ensure suitability. Test coupons are available free of charge from ACO.

Polymer concrete is not affected by road de-icing salts, and conforms to ASTM - B117 Salt Spray Test.

Important considerations for chemical environments
When reviewing potential applications of trench drains in chemical environments, the following issues should be considered;

1. Type(s) & mixture of chemical(s).
2. Concentration percentages.
3. Contact time with trench system.
4. Temperatures of chemicals flowing into the trench drain. (180 ° F - 82 ° C max).
5. Flushing system employed to clear chemicals from the system.
6. Cleaning agents should be checked for compatibility with trench materials.
7. ACO coupons can be used for final determination of chemical resistance.
8. Grate, locking mechanism, edge rail, outlet and trash bucket materials should be checked for chemical resistance.
9. Check sealant for compatibility.
