Chemical Resistance

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.

Whitford thin-film Xylan® and Xylar® coatings offer key properties:

  • Chemical resilience
  • High thermal stability
  • Low coefficient of friction
  • Other high-performance properties

Thin films are always subject to some permeation but Whitford’s products are often used as additional protection over corrosion-resistant primers. Whitford’s powder products allow for increased thickness and permeation resistance. Discover our products here!

It is important to consider the coating chosen for effective chemical resistance as there are various external factors that can have an impact:

  • Chemical concentration
  • Chemical substance the component is exposed to
  • Degree of exposure (full, part)
  • Duration of exposure (permanent, temporary)
  • Temperature (environment and chemical substance)

Whitford’s chemical resistant coatings have benefits for and are sold into various markets:

  • Automotive
  • Energy
  • Others: O-rings, Reprographics, Waste Water
