WEICON Contact VA 100 Cyanoacrylate Adhesive

WEICON Contact VA 100 Cyanoacrylate Adhesive is a liquid industrial adhesive designed for fast bonding of metal, plastic, and rubber. Its medium-viscosity structure makes controlled application on small parts easier while providing practicality in serial assembly processes. Because it forms an initial bond very quickly under the effect of moisture, it is positioned as a time-saving solution in maintenance and production lines. The manufacturer is WEICON, and the product is part of WEICON’s Germany-based portfolio.

Bonding approach targeted with Contact VA 100
This industrial adhesive is described as a “general-purpose” solution, especially for bonding metal, plastic, and rubber parts to each other. Since the bond line works as a thin film, it provides more stable results in joint geometries where good surface contact is achieved. The fact that it is silicone-free and forms a colorless film after curing is an advantage for applications where a visually clean bond is required. In addition, having compliance declarations for certain food-contact regulations can make specification compliance easier in some industrial areas.

Application method and surface preparation
In application, the adhesive is typically applied to only one of the surfaces, and the parts are quickly joined and held in place. Keeping surfaces clean, dry, and free from oil is the main factor determining bond quality; dirt and moisture can reduce adhesion. Because excessive application thickness can negatively affect curing, a thin and controlled film should be targeted. For large-area bonding, a spot application approach is described as a practical method to reduce internal stresses.

Technical structure, curing behavior, and performance notes
The product is an ethyl-based cyanoacrylate and, thanks to its medium viscosity range, offers an industrial adhesive profile with low tendency to run and more manageable dosing. The maximum gap-bridging capacity specified at 0.15 mm indicates more efficient results when parts fit closely together. The initial setting time is on the order of seconds depending on the substrate, and a full curing time of 24 hours should be considered for final strength. Thermal parameters such as the temperature resistance range and softening temperature support selecting the right product according to the operating temperature of the part.

Applications, compatible substrates, and key advantages
It is preferred for metal brackets, plastic housing parts, rubber seals, small component assemblies, and maintenance tasks requiring fast fixation. In automotive supply, machine manufacturing, electrical/electronics assembly, maintenance and repair, and general industrial production, it provides quick initial bonding and a clean bond line in small areas. Its medium viscosity helps reduce dripping risk while enabling controlled application through dosing and making part alignment easier to manage. On the specification side, the documentation briefly mentions ISEGA certification and relevant code information, which can provide practicality in procurement and compliance processes.
