Transportation and Storage:
While in transportation and storage, never put the panels in direct contact with cements and paints, both of which are
extremely incompatible with polycarbonate. Always utilize thick wooden boards to isolate the panels from contact with
cements and paints while transporting or storing. The sheets must be stored horizontally on a flat surface and kept
away from direct sunlight. Original crating is not sufficient to protect panels from solar damage. If left in the sun or
excessive heat, the protective film on the sheets may become difficult to remove. Do not stack sheets covered or
uncovered in direct sunlight. Stacking may cause the sheets to heat up and distort. Always keep stacked sheets in a well-
protected and shaded area during storage and installation. The longest sheet should be at the bottom of stack. Prevent
moisture from getting between stored sheets, as this may cause whitening. Allow for ventilation, particularly at the
highest point, to minimize heat build-up and provide air circulation. Under single skin roofs of any sort and especially in
cold temperature, condensation is generally unavoidable. Good ventilation will always help minimize condensation.
Protective Film:
Multiwall polycarbonate sheets come with a protective film. This film protects the panels from scratches and provides
panel information. Keep the film on the panels until they are installed. If needed for fastening, remove several inches of
film from the edges during installation. Remove the film as soon as sheets are fully installed.
Cleaning:
Polycarbonate resin and panels are not resistant to abrasion. Please clean polycarbonate panels in accordance with
guidelines provided to maintain polycarbonate sheets for long term use.
 Gently wash sheets with a clean sponge or soft cloth, using lukewarm soapy water or mild detergent.
 Rinse sheets with lukewarm water.
 Dry sheets with soft cloth to prevent water spotting.
 Do not scrub or use brushes, brooms, or any cleaning tool that may easily cause abrasion.
 Never use corrosive chemical detergents.
 To remove adhesive agents or spots left by masking films or logos, utilize kerosene or alcohol solvents with soft
cloth.
 Do not use gasoline.
 Wash sheets again after applying the above mentioned cleaning materials
Chemical Resistance:
Use only 100% Silicone sealant
Do not put polycarbonate in contact with PVC.
Multiwall polycarbonate sheet is generally unaffected by acids, alcohol, glycols, mineral oil, animal and vegetable fats,
kerosene and non-abrasive cleaners.
Multiwall polycarbonate sheet is affected by benzene, petrol, ketones, acetone, phenols, chlorinated and aromatic
hydrocarbons, petroleum-based paints, abrasive cleaners and solvents Acetaldchyde, acetate acid, acetone, acrylonitrile,
ammonia, hydrogen floride, hydrogensulphide, benzone,benzoate acid, benzoate alcohol, calcium nitrate bormoxynil,
phenol, carbon disulfide, carbon tetrachloride, 5%potassium hydroxide. Solutions, 5% sodium hydroxide solutions or
