Product Name
SciGrip SG100 UV Resistant Toughened 15 min & 40 min White 490ml 10:1 MMA Methacrylate Adhesive 30191
Brief Description
The SciGrip SG100 Series is a two-component, 10:1 mix ratio, bright white, UV resistant, and toughened Methyl Methacrylate (MMA) structural adhesive. It is engineered for high-strength bonding of various substrates, including thermoplastics, metals, and composites, offering rapid curing at room temperature.
Popular Applications & Uses
- Bonding aluminum panels.- Strengthening side and roof panels, door panels, and aerodynamic components for trucks and construction equipment.- Bonding magnets in electric motors and loudspeakers.- Composite bonding for truck trailer beds and various composite components such as fenders, stiffeners, and sliding roofs.- Bonding hulls, deck liners, ski boats, yachts, and various internal fixtures for watercraft.- Excellent for bonding FRP composites, gel-coated surfaces, and thermoplastics.- Signage and displays, including bonding acrylic panels, frames, and metal supports.- Attaching panels and brackets in automotive and transport applications.- Joining aluminum, steel, or powder-coated parts in metal fabrication.- Joining ABS, acrylic, PVC, or polycarbonate in plastic fabrication.- Topside applications in marine environments, such as deck exteriors and hardtops.- Bonding items built in 2-part molds, like hatches and doors.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Fabrication (Composite, Metal, Plastic)- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/ Specialty Vehicle
Special and Unique Features
- UV resistant formulation, maintaining a bright white color for color-critical applications.- Toughened properties provide excellent fatigue, impact, and shock load resistance.- Requires minimal surface preparation, which helps reduce labor and production cycle time.- Available with a choice of 15-minute and 40-minute working times to suit various application and process requirements.- Non-sag handling characteristics facilitate application on non-level or vertical surfaces.- Offers excellent environmental and chemical resistance, ensuring permanent bonds in harsh operating environments.- Capable of forming strong bonds with dissimilar materials, such as metal to plastic or composites.- Cures rapidly at room temperature, achieving full bond strength shortly after application.- Exhibits low shrinkage, ensuring precise bonding and dimensional stability.
Key Properties
- Type: Two-component Methyl Methacrylate (MMA) structural adhesive.- Mix Ratio (by volume): 10:1 (Part A: Part B).- Color (Mixed): Bright White.- Working Time: 12-18 minutes (SG100-15) or 35-45 minutes (SG100-40).- Fixture Time: 30-45 minutes (SG100-15) or 80-100 minutes (SG100-40).- Tensile Strength: 2,500-2,900 psi (17.2-20 MPa).- Shear Strength: 2,000-2,400 psi (14-16 MPa).- Maximum Tensile Elongation: 80-120%.- Service Temperature: -40 to 180°F (-40 to 82°C).- Gap Fill: 0.02-0.5 inches (0.50-12.7 mm).
Surface Compatibility
- Thermoplastics: Including Acrylic, ABS, PVC, Polycarbonate, and Styrenics.- Metals: Such as Aluminum, Coated/Painted Metals, Sheet Metal, Stainless Steel, and Cold Rolled Steel. (Note: All metals require a primer, especially stainless steel and aluminum, for optimal bonding.)- Composites: Including Fiberglass, Gelcoats, RTM, RTM Light, Vinylester, Polyester, and Epoxy.- Magnets.- Wood.
Known backups / known substitutes
- Other Methyl Methacrylate Adhesives (MMAs) from alternative brands like Infinity Bond or Plexus.- Epoxy adhesives, though MMAs generally offer greater flexibility, toughness, faster cure times, and require less surface preparation.- Polyurethane adhesives, where MMAs often require less extensive surface preparation and priming.- Mechanical fasteners (e.g., bolts, screws) or welding, which MMAs can replace to offer cost and labor savings, improved aesthetics, and better stress distribution.
Comparison Note
SCIGRIP SG100 MMA adhesives offer significant advantages over traditional bonding methods like mechanical fasteners or welding, and other structural adhesives such as epoxies and polyurethanes. They provide superior flexibility, toughness, and impact resistance, particularly for bonding dissimilar materials, and cure rapidly at room temperature with minimal surface preparation. The product's UV resistance and bright white color make it an ideal choice for aesthetic and outdoor applications where long-term color stability and appearance are crucial.
