To help manufacturers with their bonding needs, adhesives and dispensing specialist Intertronics presents SCIGRIP SG300, a two-component structural methyl methacrylate adhesive (MMA) for bonding metals, composites, and plastics without the use of primers and with little to no surface preparation. The adhesive is ideal for applications where the risks of vibration and impact are prevalent, as it can withstand the resultant stresses, whilst maintaining bond strength.
Developed specifically for the transport industry, SCIGRIP SG300 is suitable for primerless metal, composite, and plastic bonding in the automotive, rail, and marine sectors. In addition, it can be used for various infrastructure products including in wind energy and agriculture. The adhesive can bond a variety of materials to each other including metals, plastics, and composites, as well as cross-bonding materials (metals to plastics, plastics to composites, etc).
“SCIGRIP SG300 is a very popular ‘workhorse’ 10:1 MMA structural adhesive,” explained Ben Swanson, Joint Managing Director at Intertronics. “By offering a combination of strong bonding properties, fast cure, ease of use, and versatility across materials, it provides an efficient and effective solution for many structural bonding needs in industrial applications.”
SG300 is designed to offer reduced read through on surfaces made from thin gauge metals, removing post finishing requirements and boosting aesthetics. SG300 is certified to EN45545-2 2013, the European safety standard for Fire, Smoke and Toxicity (FST) for use in rail construction. It has DNV and Lloyd’s Register approvals for ship building and has been tested for long-term undersea applications.
Unlike mechanical fasteners, SG300 dampens vibration and absorbs shock loads. It is shown to have excellent fatigue impact resistance and works in temperature conditions from -4 degrees Celsius to 82 degrees Celsius.
Depending on the needs of the assembly process, SG300 comes with three speed options. For small-sized jobs the application has a five-minute open time which can be used for small metal clips to composite panels, 15-minute open time for medium-sized jobs including bonding generator covers to interior steel stiffeners, and 40-minute open time for bigger jobs including bonding large wall trailer panels to metal frames of a lorry.
