Multi Wall Sheet

 

Transport, Storage

 

Pad and pack polycarbonate sheets in flat position. Store in a sheltered, clean, dry and free from dust warehouse; away from direct sunlight/rain.

Do not store or expose the products to direct sunlight for a long time. Doing so may cause difficulty in removing the protective film, deformation to the products in summer season, and/or cracks in winter season.

Must avoid storing the products along with a chemical agent (organic agent such as thinner, gasoline, lamp oil, or anti-rust oil) in a storehouse or a room. Doing so may cause damage on the products.


Maximum stacking height 2 m with one pallet. Avoid scratching and placing heavy substances on top.


 

General Advice

The UV protected side should face upwards (masking with print).


Don’t remove/damage masking until installation is completed.


Remove ~ 5cm of masking from all polycarbonate sheet edges before the installation.


Remove masking once installed and cover it immediately until completion of the construction project.


 

General Instruction

Don’t step/walk on polycarbonate sheets. Use a wooden beam/other devices to temporarily support the roof during the installation.


Avoid using sharp tools on the polycarbonate sheets‘ surface and direct nailing. A smooth cut of the surface is important to prevent any crush damage.


Provide suitable space for thermal expansion and cold shrinking. Linear Expansion Coefficient of PC is 0.065mm/m.℃


  • Sealant and gaskets must be compatible to polycarbonate .
  • When using a silicon sealant, select an alcohol type. Using an acetoxy type silicon sealant or an oxime type silicon sealant may cause surface corrosion and/or solvent cracks on the product. do not use the incompatible amino, benzamide or methoxy curing silicone sealant,
  • Sufficient drying and ventilation is required when you use a silicon sealant.
  • the PVC gaskets and caoutchouc must not be used at all.

 

Handling

Cutting tools: We recommend common circular saw (carballoy), bandsaw, jigsaw, hacksaw, portable electric saw.


Drilling tools: We recommend portable drill/bench (metal bit). Clamp firmly/tightly with strong support while cutting and drilling.


Don’t bend the polycarbonate sheets with the generatrix parallel to honeycombs during cold bending.


The minimum curve radius should be 175 times the thickness of the polycarbonate sheets in normal atmospheric condition. The sheet of X type and thickness ≥ 16mm cannot be cold bended.


Blow away swarf and dust by dry clean compressed air.


Seal edges with anti-dust tape to prevent dust and algae growth.


 

Maintenance, Cleaning

Avoid any contact with alkaline, alkali salts, amines, ketenes, aldehydes, esters, ethers, chlorinated hydrocarbons, aromatic hydrocarbons, methanol and isopropanol etc.


Rinse polycarbonate sheets with lukewarm water (below 60 °C). Wash gently with mild soap/detergent by using a soft cloth/sponge to clear the dirt and grime.


Don’t scrub with brushes/rough fiber. Rinse second time, dry with soft cloth/chamois to prevent water spotting. Rub gently with welled VM&P naphtha, kerosene or anhydrous ethyl alcohol cloth to remove grease, wet paint/stickers.
