Cleaning and Maintenance:

Danpalon polycarbonate sheets have good chemical resistance, at room temperature, to a variety of dilute organic and inorganic acids. Water, vegetable oils, solutions of natural salts, aliphatic hydrocarbons and alcohols are also included in this category.

Some chemical substances may attack Danpalon polycarbonate sheets. Among them are low molecular weight aldehydes and ethers, ketones, esters, aromatic hydrocarbons, perchlorinated hydrocarbons, acetone and xylene.

Danpalon polycarbonate sheets are not compatible with alkalines, alkali salts, amines and high ozone concentrations.

Cleaning:

For small areas:

• Rinse the sheet with lukewarm water.
• Wash the sheets with a solution of mild soap or household detergent and lukewarm water, using a soft cloth or a sponge in one direction only to loosen any dirt and grime.
• Rinse with cold water and dry with a soft cloth in one direction only to prevent water spotting.
• To remove labels, stickers etc, the use of kerosene, neptha or white spirits is generally effective. Afterwards, repeat steps 1 to 3 above.

For large areas:

• Clean surface with a high pressure water and/or steam cleaner. (No more than 80oC)
• Use of additives to the water should be restricted to those compatible with Danpalon polycarbonate sheets.
• Recommended solvent cleaners are: White Spirit, Petroleum Ether (BP65), Hexane and Heptane.

When cleaning bent Danpalon sheets, it is recommended to try the solvent first on a bent sample of the material for a few hours, if no visible discolouration has occurred apply the solvent on the whole area.

Important:

Never use abrasive or highly alkaline cleaners on Danpalon polycarbonate sheets. Cleaners and solvent generally recommended for use on polycarbonate are not necessarily compatible with the UV Protected surface of the Danpalon polycarbonate sheets.

Do not use either BUTYL CELLOSOLVE or ISOPROPANOL on the UV protected surface of Danpalon polycarbonate sheets. Never scrub with brushes, steel wool or other abrasive a material.

Maintenance:

For maintenance purposes ‘walking boards’ should be used across the connectors. The boards themselves should be in accordance with Australian OH&S Standards and should be used according to OH&S legislative guidelines.
