SM adhesive technology for producing environmentally friendly butyl tapes
Low maintenance, flexibly adaptable and efficient in consumption and application
Butyl tapes are coated sealing tapes that are highly versatile in the construction sector, such as metal, automotive, road and shipbuilding. The production of butyl tapes requires modern coating and adhesive technology. SM Klebetechnikoffers single components as well as complete coating lines for efficient butyl tape production
Depending on the application, the butyl tapes need not only to be adhesive on one or both sides, but also laminated with various materials. Butyl tapes are often used for sealing joints (e.g., between concrete slabs, roofing felt or window frames), for overlap sealing and fixing of assembly parts with corrosion and damp protection. The odourless, solvent-free sealing tapes are weatherproof and resistant to shrinking and are characterized by long durability.
The requirements of the finished butyl tape for permanently sealing joints and edges vary greatly depending on the application – from tough and hard to very soft, and from highly adhesive to less adhesive. For this reason, modern, flexible, scalable application systems are necessary for economical production and butyl processing.
Leap in efficiency – wide slot nozzles for flexible butyl processing
Modular wide slot nozzle technology enables the production of ready-to-use butyl tapes in standard and special sizes with variable adjustable coating width and edge-to-edge coating. The coating thickness can be precisely controlled between 0.6 and 2.0 mm. Depending on the production requirements, the application temperature and quantity can easily be adapted to the process and also adjusted inline where required. “Butyl is solvent-free and therefore more environmentally friendly than other adhesives. At the same time, its properties do not change over years. That’s why butyl tapes are so widely used. With our reliable wide slot nozzle technology and the numerous lamination options, we enable our customers in covering a wide range of production,” explains René Schog, Managing Director of SM Klebetechnik.
Laminated butyl tapes for permanent sealing
Due to laminating butyl tapes with various backing materials, they are popular in construction and many different industries. Coating with aluminium, non-woven materials, EPDM, polyester, fleece or paper is possible. Butyl trilaminates or semi-finished products for further processing by your customers can also be produced with the coating systems from SM Klebetechnik. In order to prevent the adhesive bonding compounds from coming into contact with each other (e.g., while winding the adhesive tapes), a Releaseliner cover with suitable separation materials can be integrated in the production process.
Maintenance, converting production or new production line for butyl processing?
The individual case decides. SM Klebetechnik works with you to develop the appropriate, low-maintenance line concept for producing ready-to-use butyl tapes. This includes the modernisation of existing lines as well as the planning and implementation of new coating lines. Upon request, SM Klebetechnik can supply you with everything from a single source.
Conversion to drum melters and maintenance with individual components
You can replace defective or inefficient components with individual components from SM Klebetechnik as part of the retrofit modernisation. In particular, filling your system via drum melters or extruders brings a significant increase in efficiency. In particular, the conversion from butyl blocks to drum melters with strong melting performance and high flow rates for filling the coating line leads, in practice, to easier handling and noticeable cost savings.
