Coatings

Abstract

Different object properties are enhanced by coating: hardness, durability, longevity, elasticity, appearance, corrosion resistance, etc. Metallic coatings are frequently used. Nickel, chromium, mercury, and antimony have important sensitizing properties. Plastic and paint coatings have a wide range of applications. Direct or airborne contact with several polymers can induce irritant or allergic skin dermatitis, contact urticaria, mucosal irritation or allergy, scleroderma etc. Printed coatings are revolutionizing the printing industry. Allergic dermatitis was described in workers using different dyes. Other coatings (natural gum, waxes) are mainly present in the food industry and in the drug industry. Some components can induce allergic reactions (arabic gum, beeswax), acne (organochloride compounds), etc.
