For all ceramic coatings, direct contact with concentrated acids should be avoided, both on the work and on a daily basis.

 

For this, observe which resistance indicated by the manufacturer (packaging/catalog/internet) has the ceramic coating purchased, following the guidance below.

 

GA: Enameled product resistant to chemicals for household use and pool water treatment;

 

GLB: Medium resistance to low concentration chemicals (visible effects).

 

UA: Non-enameled product resistant to household chemicals.

 

*For specification, use and maintenance with chemicals, contact the manufacturer.

The test method for determining resistance to chemical attack is described in Annex H in technical standard NBR 13818.
