Scigrip SG800 High Temperature MMA Methyl Methacrylate Adhesive is designed to withstand temperatures up to 150°C over prolonged periods and is suitable for applications like under the bonnet engine bay component assembly and metal bonding prior to paint baking cycles.

MMAs are fast curing, two-part adhesives that cure on mix at room temperature to form resilient bonds. They are commonly used in industries like marine, transportation, rail, automotive, and many others for structural bonding of metals, plastics, and composites. The materials adhere well to a range of substrates. MMA technology bridges a gap between epoxy and polyurethane adhesives, offering toughness, fatigue resistance, and high peel strength while maintaining high lap sheer performance.

Scigrip SG800 has several characteristics that make it suitable for variety of assembly operations, including its ability to provide a primerless metal bond that requires little to no surface preparation by the user. Formulations are available with different working times (4 to 15 minutes), to provide flexibility for a variety of transportation and industrial assembly operations — keeping assembly lines moving at the customer’s pace. For straightforward application, SG800 is supplied in pre-measured, side-by-side double syringe cartridges and includes static mixing nozzles.

At high temperatures, SG800 is expected to have good strength retention and environmental and chemical resistance. The material performs well in industry standard tests including ASTM D3163 and truck manufacturer PACCAR’s CMT038.

Ben Swanson, chief commercial officer at Intertronics, said: “SG800 is specially formulated to meet the needs of the bus, truck, and rail industries. However, it can be applied in broader applications and we will be able to recommend it to trial to our customers who are metal bonding (including aluminium, mild steel, stainless steel, or coated metals), and bonding metal components prior to paint bake cycling, who might benefit from its excellent properties and flexible, straightforward workflow.”
