High quality blended cyanoacrylate adhesive surface insensitive gel. Produces strong bond between a variety of materials including plastics, rubbers, metals, paper, card and leather. This adhesive can be applied using our syringe barrel dispensers or direct from the tube. All adhesives are shipped with TDS and MSDS and are European manufactured materials. This grade is suitable for bonding difficult substrates, absorbent and porous surfaces, e.g. paper, wood, cardboard and leather as well as superfast cure with plastics, metals, ceramics, and rubbers.
Due to the surface insensitive nature of GB44, this grade also maintains a rapid fixture time on acidic surfaces such as wood, leather and dichromated metals. GB44 is used in a wide cross section of industrial applications including automotive, white goods and furniture manufacturing. Typical examples include bonding centre consoles, dashboards and weather stripping. Bonding identification tags to equipment. Bonding rubber pads to equipment base or legs. Bonding components in a loud speaker cone. Bonding leather and rubber during shoe manufacture. Bonding fabric on lampshades.
Directions For Use
1. Make sure the surfaces to be bonded are clean and dry.
2. Dispense adhesive to one surface only. Apply only enough to leave a thin film after compression.
3. Press parts together and hold firmly for a few seconds. (Maximum strength is achieved in 24 hours).
4. Procure activator can be used to cure exposed adhesive outside of the joint, to help prevent blooming.
5. Wipe off excess adhesive from the top of the container and recap.
Activation
Activators may be used with cyanoacrylates where a faster cure speed is required. Fixture times of less than 2 seconds can be obtained with most cyanoacrylates. Testing on the parts to measure the effect is recommended.
Priming
Primer is recommended for use on low energy plastic surfaces such as polyethylene, polypropylene, PTFE and thermoplastic rubber materials.
Apply to one surface only. Primer also has a mild activating effect which may accelerate the cure speed of cyanoacrylate adhesives.
Debonding
Cured cyanoacrylate may be removed from most substrates, and parts disassembled, with our debonder – however, ensure to test compatibility of the substrate with debonder first as this may dissolve some plastics.
It might not be possible to fully remove cyanoacrylate from fabrics.
Dispensing
Factors that affect dispensing are pressure, time and needle size. As a general reference low viscosity liquid would need a small needle diameter and less pressure, a high viscosity liquid would need a larger needle diameter (tapered recommended) with higher pressure to dispense. Information on the recommended hand dispensing tip can be found in the Technical Data Sheet (TDS).
