SciGrip SG230HV Non-Sag Toughened 60 min Gray 490ml 10:1 MMA Adhesive for Large Gap Filling and Large Structures

Product Name

SciGrip SG230HV For Large Structures Non-Sag Toughened 60 min Gray 490ml 10:1 MMA Methacrylate Adhesive SG230HV-30-G

Brief Description

The SciGrip SG230HV is a two-component, 10:1 mix ratio, high-viscosity Methyl Methacrylate (MMA) structural adhesive specifically formulated for bonding large composite, plastic, and metal parts. It offers a 60-minute working time, is non-sagging for vertical applications, and provides a tough, permanent bond with excellent resistance to environmental factors and dynamic loads.

Popular Applications & Uses

- Bonding large structural parts requiring extended working times- Filling deep and irregular gaps up to 1.5 inches (39 mm)- Marine hull bonding, deck liners, and internal fixtures- Exterior automotive applications, vehicle roofs, spoilers, and panels- Construction applications, including bonding aluminum composite panels to buildings- Rail industry for bonding interior and exterior panels, seating, windows, and door assemblies- Wind turbine components- Bonding magnets in electric motor manufacturing- Signage and display assembly, including acrylic panels and metal supports

Industries that Commonly Use It

- Automotive Service/Repair- Construction/ Building Services- Energy (e.g., wind turbines)- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/ Specialty Vehicle

Special and Unique Features

- Non-sag, high-viscosity formulation that stays put on vertical or inverted surfaces- Toughened for exceptional fatigue, impact, and shock load resistance- Minimal to no surface preparation required for many substrates, especially composites- Bonds dissimilar materials effectively- Excellent environmental, moisture, fuel, and chemical resistance- Reduced emissions and low odor, particularly after cure- Meets EN45545-2 2013 European safety standard for Fire, Smoke and Toxicity (FST) in rail construction

Key Properties

Known backups / known substitutes

- Other SCIGRIP MMA Adhesives (e.g., other SG230HV series with different working times)- Other brands of Methyl Methacrylate (MMA) structural adhesives (e.g., Bostik SAF & FIT, Permabond MMAs, Infinity Bond MMA 422)- Epoxy Adhesives (generally more brittle, slower cure, and less effective on dissimilar materials compared to MMAs)- Polyurethane (PU) Adhesives (different properties and processing benefits compared to MMAs)

Comparison Note

SciGrip SG230HV, as a 10:1 MMA structural adhesive, offers a unique balance of high strength, toughness, and flexibility, particularly beneficial for large assemblies and dynamic environments where dissimilar materials are joined. Its extended 60-minute working time allows for precise positioning and assembly of large components, a key advantage over faster-curing alternatives. Compared to many epoxies, MMAs like SG230HV provide superior impact and peel strength, faster room-temperature cure, and require less rigorous surface preparation, making them highly efficient for production lines.
