Contact VA 110 cyanoacrylate adhesive pen system 30 g

Liquid one-component superglue with dosing tip. Weicon VA 110 is a cyanoacrylate adhesive with NSF approval, which can be used in sensitive areas such as the food and drinking water sector, in the pharmaceutical industry or in the manufacture of toys for bonding rubber and plastic.

Particularly suitable for connecting metal, plastic and rubber with one another.
Cyanoacrylate adhesive for special requirements. Insensitive to prolonged exposure to moisture.

Surface pretreatment:
The prerequisite for perfect bonding are clean and dry surfaces to be bonded (cleaning and degreasing with WEICON Surface Cleaner). Smooth surfaces should be roughened mechanically. To improve the adhesion of plastics that are difficult to bond (e.g. PE, PP, POM, PTFE), thermoplastic elastomers (TPE) and silicones, WEICON CA-Primer can be applied to the adhesive surface.

Processing:

• The Contact cyanoacrylate adhesive is only applied to one of the surfaces to be bonded.
• The layer thickness of the adhesive application should be between a minimum of 0.05 mm and a maximum of 0.2 mm (depending on the type), otherwise curing cannot be guaranteed.
• When bonding large areas, the Contact cyanoacrylate adhesive must be applied point by point in order to avoid internal tension.
• Contact cyanoacrylate adhesives are very economical. One drop is enough for approx. 3 to 5 cm² of adhesive surface.
• The parts to be bonded should be bonded at a relative humidity of 40% to 80%.
  Below 40% the hardening is slowed down or prevented very much.
  With a humidity above 80% or strongly basic substrates (e.g. glasses) there is a risk of shock hardening.
  In these cases, certain materials show a decrease in strength due to tension in the adhesive layer of 10% to 15%.
• Basically reacting surfaces (pH value greater than 7) accelerate the hardening process, acidic reacting surfaces (pH value less than 7) delay it and in extreme cases can completely prevent polymerisation.

Storage:
The Contact cyanoacrylate adhesives can be kept for at least 9 months in the unopened state at room temperature (+ 18 ° C to + 25 ° C) and in dry and dark storage, while at temperatures around + 5 ° C the shelf life can be extended to 12 months.
