Product Name

SciGrip SG800 Black Temp Resistant Primerless Nonsag Gel 05 & 15 min 490ml 10:1 MMA Methacrylate Adhesive

Brief Description

SciGrip SG800 is a high-performance, two-component methyl methacrylate (MMA) structural adhesive designed for robust bonding of metals, plastics, and composites. It features excellent temperature resistance, primerless adhesion to most metals, and a non-sag gel consistency for versatile application. Available with 5-minute and 15-minute working times, it offers fast cure and high strength development.

Popular Applications & Uses

- Structural bonding of dissimilar materials like metal to plastic or composites.- Bonding metal components prior to paint bake cycling or powder coating.- Automotive panel bonding and assembly of engine bay components.- Manufacturing of trucks, buses, rail, and construction equipment, including side and roof panels, and aerodynamic components.- Marine applications such as bonding hulls, deck liners, and internal fixtures for boats, canoes, and kayaks.- Bonding magnets in electric motor manufacturing and loudspeaker production.- Assembly operations requiring high temperature strength, fatigue, and impact resistance.

Industries that Commonly Use It

- Transportation/ Specialty Vehicle (e.g., bus, truck, rail, RV, agricultural, ambulance, fire trucks)- Marine (commercial and recreational)- Metal Fabrication- Plastic Fabrication- General Manufacturing- Aerospace/Defense- Construction/ Building Services- Automotive Service/Repair- Fabrication- Sign & Display

Special and Unique Features

- Primerless metal bonding, reducing surface preparation time and effort.- High-temperature resistance, performing in continuous environments up to 300°F (150°C) and intermittent exposure up to 400°F (204°C).- Non-sag gel formula ensures precise application on vertical or uneven surfaces without dripping or running.- Fast working and fixture times (05 and 15 minute options) for quick assembly processes.- Low bond-line read-through on show surfaces, minimizing finishing requirements.- Excellent fatigue and impact resistance.- Ability to bond dissimilar materials with different flexibility.

Known backups / known substitutes

- Other MMA adhesives from manufacturers like Plexus, 3M, Lord, or Sika.- Structural epoxies or polyurethanes, though MMAs often offer faster cure times and better impact resistance.- Cyanoacrylate adhesives for certain applications requiring fast bonding, but may differ in flexibility and gap-filling.

Comparison Note

SciGrip SG800 MMA adhesive stands out from many epoxies and polyurethanes due to its rapid cure at room temperature, superior impact resistance, and ability to bond a wide range of dissimilar materials, including many plastics that epoxies may struggle with. Its primerless adhesion to metals significantly reduces surface preparation, saving time and labor compared to traditional fastening methods like welding or riveting. The non-sag gel consistency and excellent temperature resistance make it particularly suitable for demanding structural applications in various industries.
