the selective solvents for polycarbonate [PC] is cresol and dichloromethane, PC can be also dissolved in dimethyl formamide and/or in chloroform.

“How do I fix my John Deere lawn tractor hood?” they ask. “It’s made of ‘plastic’.” they say. The “plastic” from which *most* John Deere lawn tractors are made is polycarbonate. When a polycarbonate bumper gets in a collision (especially in freezing weather), the bumper would shatter and not absorb much of the impact.

Epoxide glue, also known as epoxy, is a simple way to glue polycarbonate together….Using Epoxy to Glue Polycarbonate

1. If using two-part epoxy, mix the two parts together by following the instructions on the back of the packaging.
2. Apply epoxy to a clean part of the polycarbonate that you would like to glue.

Polycarbonate offers much more resilience than acrylic, making it ideal for highly demanding applications like bullet-resistant windows. Acrylic has a high gloss finish and is more transparent, making it ideal for display cases. Acrylic is also easier to crack, while polycarbonate is easier to scratch.

Silicone sealants do not degrade in sunlight. This sealant adheres to polycarbonate, fiberglass, masonry, painted aluminum, painted steel, glass*, and wood. Application temperature range: between 40° F to 105° F (5° C to 40° C). Apply to dry material.

Dow Corning Dowsil 799 neutral cure silicone sealant with advanced adhesion to PVCU for use in glazing applications that utilise polycarbonate and perspex sheeting, Perimeter pointing of door and window frames applications, It has excellent adhesion to porous and non-porous substrates.

ALSEAL Polycarbonate Sealant is a one-component, 100% neutral cure silicone sealant specially formulated for polycarbonate bonding including those with anti-scratch coatings. Forms waterproof and permanently flexible seals on polycarbonate and other plastic sheet materials in roofing and cladding applications.

Fitting End Closure To Sheets Ens closure should be sealed on to the polycarbonate sheets using a low modulus neutral cure silicone (such as the Soudal LMN silicone available from ourselves).

You should never walk on polycarbonate roofing unless it’s well-supported underneath. While polycarbonate roofing can sustain a lot of abuse, it’s not meant to support the weight of a person. The surface is slippery and you will likely fall. Further, you can dent and scratch it if you walk on it.

Both types of polycarbonate roofing last anywhere from 10 to 20 years. Some manufacturers however do warranty their products for the lifetime use of the home.

The Effisus Easyrepair Tape is the ideal solution to seal joints on polycarbonate sheets. It creates a waterproof, moisture, and airtight barrier, with no additional sealing required. It has an exceptional adhesiveness to polycarbonate and is installed in a fast and easy process.

Due to the fact that multiwall polycarbonate cannot be totally hermetically sealed, small amounts of condensation may be unavoidable in circumstances. However, experience has taught us that many of the worst cases are invariably due to incorrect installation and / or use of poor quality drip trim.

This can be easily fixed by resealing the void underneath the flashing. Another reason for leaks could be perished seals. Even if your structure seems to be structurally intact, the seals may have perished and could be the cause for letting in water.

Flashband doesn’t work well with poly. You need butyl flashing instead. Doesn’t react with silicone either.

Butyl synthetic rubber adhesive is designed to provide a secure seal between metal panels in metal roofing and metal siding applications. When installed between each panel overlap, butyl tape forms an effective weather barrier against moisture, dirt, air, and allergens.

You should make sure that the polycarbonate sheets are the right way up! Polycarbonate sheets will only have one side that’s protected from UV, so you will need to make sure that side is facing up towards the sun.
