Sealing

      Sealing applications

There are many sealing applications in industry and many solutions for achieving a sealed joint.

The most common applications are :

• Sealing around the openings of rolling stock – Sealants in cartridges or in strips ensure perfect sealing of sky dome products, windows and other openings on caravans or motorhomes.

• Anti-dust protection – The edges of plastic sheets, used especially in the manufacturing of verandas, can be closed with a specific adhesive tape that allows for the circulation of air but ensures a barrier against insects and other foreign bodies.

• Bonding panels – The bus and special vehicle manufacturing industry heavily uses sealants in cartridges for bonding panels. Sealants offer effective bonding with a flexible bonding joint that is resistant to the slight deformations that occur during the normal life cycle of the vehicles. 

• Containment – Adhesive tapes are commonly used in industries that require optimal containment. During asbestos removal in contained areas, airtight sealing of waste is possible with a specific adhesive. In the nuclear industry, a specific cloth PMUC adhesive can be used for a large number of applications while respecting the strict regulations of this type of industry. 

• Vacuum molding – The vacuum molding method involves covering the laminated part with a vacuum plastic film that is sealed all around with a preformed butyl mastic sealant. This sealant can withstand baking temperatures in ovens or autoclaves up to 200°C.

      The main sealing products

• Single sided cloth adhesive tape : Good mechanical resistance, hand tearable, strong initial adhesion (Example : Adezif TO 115 waterproof scotch adhesive).
   
• Double-sided foam adhesive tape : To ensure the sealing of an assembly, it is necessary to use a closed-cell foam.
   
• Single-sided PE adhesive tape : To repare the PE tarpaulins  for greenhouses or growing tunnels. Excellent UV resistance et economical.
   
• Preformed butyl sealant : Immediate sealing, long lifetime, does not dry out. Several dimensions available.
   
• Sealants in cartridges : Single or two-component, joint thickness of several centimetres possible, good UV and hydrocarbon resistance.
