SCIGRIP SG300 MMA Methyl Methacrylate Adhesive, 10:1
About SCIGRIP SG300 MMA Methyl Methacrylate Adhesive, 10:1
SCIGRIP® SG300 MMA Methyl Methacrylate Adhesives are two-component 10:1 products for bonding metals, composites, and plastics without the use of primers and with little to no surface preparation. A strong candidate for applications where the risks of vibration and impact are prevalent, its resiliency allows this adhesive to withstand impact and vibration stresses, whilst maintaining bond line strength.
Developed to meet specific requirements of the transport industry, SCIGRIP SG300 is designed to offer reduced read through on show surfaces made from thin gauge metals, removing post finishing requirements and boosting aesthetics. SG300 meets EN45545-2 2013, the European safety standard for Fire, Smoke and Toxicity (FST) for use in rail construction. It is DNV-GL and LR approved for boat building.
SG300 is a very popular, “workhorse” 10:1 MMA structural adhesive.
SCIGRIP SG300 is supplied in pre-measured, side-by-side double syringe cartridges and includes static mixing nozzles for straightforward application.
