 Mild attack - aqueous 1% & 5% at ambient temperature  Water - accelerates corrosion  At 40°C - Butyl Rubber is resistant  At 70°C - Butyl Rubber is not resistant * Coat glass with Clear Shield ND No Data 1. Varies with agitation and presence of Nitrogen Oxide 2. Alum/SS304: Not resistant when Sulphur Dioxide is wet

Industrial luminaires are manufactured in a veriety of materials, each specifically selected as being the most resistant to chemical corrosion & other related elements. The resistance tables give a general overview regarding the resistance to chemical attack on luminaire materials and is applicable for ambient temperatures of up to 60%.
