Product Name
- SciGrip SG300-B-05 Black 5-minute High Strength Toughened 490ml 10:1 MMA Methacrylate Adhesive
Brief Description
- The SciGrip SG300-B-05 is a two-component, 10:1 mix ratio methyl methacrylate (MMA) structural adhesive designed for high-strength bonding of metals, composites, and various plastics. It offers rapid curing at room temperature, excellent impact and fatigue resistance, and requires minimal surface preparation for most applications.
Popular Applications & Uses
- Bonding metals, composites, and plastics in structural applications.- Rail carriage applications, including vertical and horizontal surfaces, cavities, dashboards, luggage storage compartments, and gangways.- Marine window bonding and large-scale bonding of ship hulls.- Automotive panel bonding and general automotive assembly.- Industrial manufacturing and product assembly operations.- Bonding aluminum composite panels in construction.- Electric motor manufacturing, such as bonding magnets to metal housings.- Signage and display assembly, including bonding acrylic panels, frames, and metal supports.- Countertop and solid-surface manufacturing for joining parts.
Industries that Commonly Use It
- Transportation/ Specialty Vehicle- Marine- General Manufacturing- Metal Fabrication- Plastic Fabrication- Construction/ Building Services- Aerospace/Defense- Automotive Service/Repair- Sign & Display- Countertop
Special and Unique Features
- 5-minute working time for fast production cycles.- High strength and toughened formulation for excellent fatigue, impact, and shock load resistance.- Primerless adhesion for most metals, simplifying bonding processes and reducing surface preparation.- Reduced bond line read-through on show surfaces, improving aesthetics and reducing post-finishing requirements.- Non-sag application characteristics, facilitating use on non-level or vertical surfaces.- Excellent environmental and chemical resistance, including salt water corrosion resistance.- Gap-filling capability up to 9.5mm (0.375 inches).- Certified to EN45545-2 2013 for rail construction (Fire, Smoke and Toxicity standards).- DNV and Lloyd's Register approvals for shipbuilding.

Known backups / known substitutes
- Other working times within the SCIGRIP SG300 series, such as SG300-15 (15-minute working time) and SG300-40 (40-minute working time), offer similar properties with different cure profiles for varied production needs.- Other brands of Methyl Methacrylate (MMA) adhesives.- Epoxies and polyurethanes are alternative structural adhesive chemistries, though MMAs often offer advantages in cure speed, surface preparation, and flexibility for dissimilar materials.
Comparison Note
- MMA adhesives like the SciGrip SG300-B-05 provide superior performance compared to traditional mechanical fasteners by distributing stress evenly, reducing noise, vibration, and harshness, lowering weight, and offering a cleaner finish.- They offer advantages over many epoxies due to faster cure times at room temperature, less stringent surface preparation requirements, and better ability to bond dissimilar materials with different coefficients of thermal expansion due to their inherent flexibility.- The SG300 series is specifically designed to reduce bond line read-through on thin gauge metals, enhancing aesthetic appeal without extensive post-finishing.
