SciGrip SG300-OW-15 Off-White 15-Minute High Strength Toughened 490ml 10:1 MMA Methacrylate Adhesive

Product Name

- SciGrip SG300-OW-15 Off-White 15-Minute High Strength Toughened 490ml 10:1 MMA Methacrylate Adhesive

Brief Description

- The SCIGRIP SG300-OW-15 is a two-component, 10:1 mix ratio Methyl Methacrylate Adhesive (MMA) designed for high-strength structural bonding. It is an off-white, toughened adhesive with a 15-minute working time, offering rapid cure at room temperature. This product is formulated to bond a wide variety of substrates, including metals, composites, and plastics, often without the need for primers on most metals.

Popular Applications & Uses

- Bonding metals, composites, and plastic parts in various assembly operations.- Attaching panels, brackets, and performing metal bonding in automotive and transport.- Strengthening side and roof panels, door panels, and aerodynamic components for trucks and construction equipment.- Bonding hulls, deck liners, ski boats, yachts, and various internal fixtures for watercraft.- Joining aluminum, steel, or powder-coated parts in metal fabrication.- Bonding magnets in loudspeaker and sweep transformer core assembly, and for electric motor manufacturing.- Joining ABS, acrylic, PVC, or polycarbonate in plastic fabrication.- Bonding acrylic panels, frames, and metal supports for signage and displays.- Suitable for mid-sized assembly operations due to its working and fixture times.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Construction/Building Services- Fabrication- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/Specialty Vehicle

Special and Unique Features

- Primerless metal bonding for most metals, reducing surface preparation time and labor.- Reduced bond line read-through, minimizing post-finishing requirements and providing a smooth, finished appearance on show surfaces.- High strength and durability, capable of forming load-bearing joints.- Excellent environmental resistance, maintaining permanent bonds in harsh operating conditions, including temperature swings, vibration, and chemical exposure.- High impact strength and fatigue endurance, resisting impact and shock loads while maintaining flexibility.- Non-sag formulation ensures precise placement on vertical or inverted surfaces.- Fast cure system with rapid strength development at room temperature, allowing parts to be used sooner.- Tolerant of poor surface conditions, such as slight oil contamination, reducing prep time.

Key Properties

- Adhesive Type: Two-component Methyl Methacrylate Adhesive (MMA).- Mix Ratio: 10:1 by volume.- Color: Off-White.- Working Time: 13-17 minutes.- Fixture Time: 30-40 minutes (time to achieve 80% of ultimate strength).- Tensile Strength: 1,700 - 2,200 psi (12 - 15 MPa).- Shear Strength: 2,300 - 2,800 psi (16 - 19 MPa).- Maximum Tensile Elongation: >40%.- Gap Fill: 0.02 - 0.375 inches (0.50 - 9.5 mm).- Service Temperature: -40 to 180°F (-40 to 82°C).- High Viscosity - Non Slump Application.

Surface Compatibility

- Metals: Aluminum, Carbon Steel, Stainless Steel, Coated & Bare Metals.- Composites: Thermoset Composites (Vinylester, Polyester, Gelcoats, Epoxy), Carbon Fiber, Fiberglass.- Plastics: ABS, Acrylics, PVC/CPVC, Polycarbonates, Styrenics, Vinyl.- Other: Magnets, Glass, Wood.- Note: Polyolefins, thermoplastic polyesters, fluorocarbon plastics, and other low surface energy plastics are generally not suitable without specialized surface treatments.

Known backups / known substitutes

- Other SCIGRIP SG300 series adhesives (e.g., SG300-05 with 4-6 min working time, SG300-40 with 35-45 min working time) offer similar properties with different working times to suit specific production needs.- Other Methyl Methacrylate Adhesives (MMAs) from various manufacturers.- Structural adhesives like two-part epoxies or polyurethanes, though MMAs offer advantages in cure speed, flexibility, and surface preparation.

Comparison Note

- SCIGRIP SG300-OW-15 offers superior performance over traditional mechanical fasteners and welding for joining dissimilar materials, providing strong, durable bonds that distribute stress evenly, reduce weight, and resist corrosion.- Compared to epoxies, MMAs like SG300-OW-15 are less brittle, more flexible, and tolerate slight mix inaccuracies better, while also curing faster at room temperature and requiring less surface preparation.- Unlike some polyurethane adhesives, MMAs generally require less extensive surface preparation and often do not necessitate priming.
