This grade has a medium viscosity (300 mPa·s), longer cure time for easy workability and residual elasticity for long lasting performance, especially in applications with changing humidity. Black in colour, this adhesive is rubber filled and displays excellent adhesion to various rubbers and plastics whilst also being suitable for bonding plastic or rubber to metal.
Weicon Contact Adhesive VA 30 Black is used for covering gaps no larger than 0.2mm. It offers excellent peel and shock resistance and is not sensitive to humidity during its long service life.
Part of the Ethyl Ester group of Weicon Contact Adhesives, Weicon VA 30 Black Adhesive is used in applications where temperatures fall between -50ºC and 135ºC. Like all Weicon Contact Adhesives, VA 30 polymerises by reacting with moisture on both the bonding surface and from the air before curing under light pressure.
If used for bonding plastics with particularly adhesive averse surfaces (e.g. polyolefines, PTFE) the surface should be pre-treated with Weicon Contact Adhesive Primer. Failure to do so will means that the Contact Adhesive cannot anchor itself to the plastic and a strong bond will be unable to form. It is suggested that users familiarise themselves with the TDS for this product before use.
Weicon Contact Adhesive VA 30 Black is available from AG in 12gm, 30gm, 60gm and 500gm packs. The 12gm, 30gm and 60gm varieties all make use of Weicon’s proprietary pen system which allows for incredibly accurate, easy application, clean processing and improved dosing.
