System overview
Chemical and corrosion resistance must be matched to an identified medium, concentration, temperature, exposure mode, substrate and existing system. DY-14 and DY-13 retain ownership of their specific product-intent searches.
Typical operating conditions
- Acid or alkali exposure
- Chemical splash or intermittent contact
- Condensate and corrosive mist
- Immersion or wash-down service
Equipment and applications
Confirm the actual substrate, exposure and operating cycle before selecting an individual product.

Selection FAQ
What information is needed to select a chemical-resistant coating?
Identify every medium, concentration, continuous and transient temperature, contact mode, cleaning chemical, substrate, existing coating and maintenance window.
Does acid resistance imply resistance to every chemical?
No. Chemical compatibility is specific to the identified medium and service condition. Do not extrapolate one resistance result to unrelated chemicals or concentrations.
How should existing coating be assessed?
Record defects, adhesion, contamination and exposure history. Retention requires compatibility and a representative trial review; unsound material must not be overcoated.
