Description

Weicon Contact VA 200 HR is a transparent cyanoacrylate adhesive with low viscosity. It shows high ageing resistance and consistently high strength, even under prolonged influence of moisture and warmth. After several days under constant influence of moisture and warmth, the cyanoacrylate adhesive shows the same high performance. Due to this high moisture resistance, VA 200 HR is suitable especially for applications exposed to varying weather conditions. The cyanoacrylate adhesive can be used in pipe and pipeline construction, for example, in the construction of kitchen and electronic devices, in tank and apparatus construction, in ventilation and air-conditioning technology, in gardening and landscaping as well as in sanitary facilities. It is suitable for various applications, such as the attachment of a control unit in a dish washer, for the production of sealings for concrete pipes, for mounting accessories in rooms with increased air humidity such as kitchens or bathrooms, for mounting components for outdoor sports such as rubber profiles to a snowboard, or for attaching armrests to outdoor furniture.
Surface pre-treatment
  • For a flawless adhesive bond, surfaces must be clean and dry (clean and degrease with WEICON Surface Cleaner). Smooth surfaces should be roughened mechanically. To improve the adhesion of plastics difficult to bond (e.g. PE, PP, POM, PTFE), thermoplastic elastomers (TPE) and silicones, WEICON CA-Primer can be applied to the bonding surface.
    • Processing
  • Apply WEICON Contact Cyanoacrylate Adhesive to just one of the bonding surfaces.
  • The layer thickness when applying the adhesive should be between min. 0.05 and max. 0.2 mm (depending on the type), as otherwise complete curing cannot be guaranteed
  • For large-surface bondings, WEICON Contact Cyanoacrylate Adhesives should be applied in dots in order to prevent inner tensions.
  • WEICON Contact Cyanoacrylate Adhesives are very economical. One drop covers approx. 3 to 5 cm² bonding surface.
  • The components should be bonded at a relative air humdity level between 40% and 80%. Below 40 %, the curing process is slowed down significantly or even prevented altogether. At an air humdity level above 80 % or with strongly basic substrates (e.g. glasses), the risk of shock-curing occurs. In these cases, certain materials show a drop in strength by 10 % to 15 % due to tensions in the adhesive layer.
  • Alkaline surfaces (pH value >7) accelerate the curing process, acidic surfaces (pH value <7) slow down the curing process and can prevent polymerisation altogether in extreme cases.
    • Storage
  • WEICON Contact Cyanocrylate Adhesives have a shelf life of at least 9 months, when stored in unopened condition at room temperature (+18 Deg.C to +25 Deg.C) in a dry and dark space. Temperatures of approx. +5 Deg.C will increase the shelf life to 12 months.
