Chemical resistance is the extent to which a material can maintain its resistance to chemicals – protecting against chemical attack or solvent reaction, determining a material’s resistance to corrosive environments.
A chemically-resistant coating is a protective layer offering maximum protection to a surface, for example, components which regularly come into contact with harmful chemicals such as solvents, oils and hydraulic fluids. Materials with low chemical resistance lose their performance levels as the materials tend to swell or soften.
Thin films are always subject to some permeation, but our products are often used as additional protection over corrosion-resistant primers. Whitford’s powder products allow for increased thickness and permeation resistance.
It is important to consider the coating chosen for effective chemical resistance as there are various external factors that can have an impact:
