Product catalog summary

Chemical Resistance of Composite Decking

Overview: This document provides a detailed analysis of the chemical resistance of composite decking materials against various substances, including oils, greases, juices, salts, acids, alkalies, solvents, and other miscellaneous substances. The resistance is categorized as spill resistant (++), limited spill resistant (+), not spill resistant (-), or unknown (0).

Oils and Greases: Composite decking shows high resistance (++ rating) to various oils and greases, including linseed, olive, castor, vegetable oils, animal fats, diesel oil, motor oil, and transmission oil. Skydrol 500 shows limited resistance (+).

Fruit and Vegetable Juices: The decking is highly resistant (++) to all tested fruit and vegetable juices, including apple, lemon, orange, grape juices, and wine, at both 20°C and 40°C.

Salts: The material is spill resistant (++) to saturated solutions of various salts such as sodium chloride, ammonium chloride, barium chloride, calcium sulphate, nickel sulphate, silver nitrate, sodium carbonate, and ferric chloride at 20°C.

Inorganic Acids: Resistance varies with concentration and temperature. Hydrochloric acid shows high resistance at lower concentrations and temperatures, while concentrated sulphuric and nitric acids show no resistance (-). Phosphoric acid shows high resistance at lower concentrations.

Organic Acids: The decking is generally resistant to citric and lactic acids at lower concentrations, but shows limited or no resistance to higher concentrations of acetic and formic acids.

Alkalies: High resistance (++) is observed with caustic soda and potash at lower concentrations. Ammonia shows limited resistance (+).

Solvents: The decking shows varied resistance to solvents. It is resistant to ethanol, cyclohexan, turpentine, petroleum, and paraffin, but shows limited or no resistance to acetone (long exposure), methylene chloride, chloroform, and n-methylpyrrolidone.

Various Substances: High resistance (++) is noted for glucose, beer, soap solution, mercury, hydrogen peroxide, distilled water, and seawater.

Recommendations: The document advises testing the products for suitability in intended applications, as the provided information is indicative and not binding. The responsibility for application and use lies with the user.

Legal Notice: All advice is given to the best of the company's knowledge but does not remove the necessity for testing. The company guarantees the quality of its products under its General Conditions.
