SciGrip SG400-LSE 50ml Polyolefin & Soft Plastics Bonder for Low Surface Energy materials MMA Methacrylate Adhesive 35967

Product Name

SciGrip SG400-LSE 50ml Polyolefin & Soft Plastics Bonder for Low Surface Energy materials MMA Methacrylate Adhesive 35967

Brief Description

SCIGRIP SG400LSE is a high-quality, two-component (10:1 mix ratio), translucent methyl methacrylate (MMA) adhesive. It is specifically engineered for bonding low surface energy (LSE) plastics such as polypropylene (PP) and polyethylene (PE) without the need for extensive surface preparation or primers. This structural adhesive also excels at cross-bonding these challenging plastics to various metals, FRP, and other plastics, making it a versatile solution for assembly and fabrication applications.

Popular Applications & Uses

- Bonding polypropylene, polyethylene, and other polyolefins.- Adhering ABS, acrylic, nylon, and LDPE.- Cross-bonding plastics to metals like aluminum and stainless steel.- Assembly and fabrication in various manufacturing processes.- Repairing blow holes in polyethylene tanks.- Replacing hot air or heat welding of plastics.- Bonding components in automotive, electronics, and signage.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair (for attaching panels, brackets, and components)- Fabrication (general, plastic, and metal fabrication)- General Manufacturing- LED/Electronics (for bonding electronic components)- Marine (for bonding fiberglass, composite materials, hulls, and deck liners)- Metal Fabrication (for joining aluminum, steel, and powder-coated parts)- Plastic Fabrication (for joining ABS, acrylic, PVC, polycarbonate, and polyolefins)- Sign & Display (for bonding acrylic panels, frames, and metal supports)- Transportation/ Specialty Vehicle (for trucks, construction equipment, recreational vehicles, and railcar manufacturing)

Special and Unique Features

- No surface preparation required for low surface energy plastics, simplifying processes and saving labor costs.- Primerless adhesion for most metals.- Fast cure time and high initial tack for efficient assembly processes.- Non-sag application, maintaining stability even when applied vertically.- Very high strength, often resulting in substrate failure before adhesive failure.- Low exotherm properties, minimizing heat generation during curing.- Creates durable cross bonds with plastics, metals, and composites.- Supplied in pre-measured, side-by-side double syringe cartridges with static mixing nozzles for easy application.

Key Properties

- Adhesive Type: Two-component methyl methacrylate (MMA) structural adhesive.- Mix Ratio: 10:1 by volume.- Color: Translucent, semi-clear when dry.- Working Time: 1-3 minutes.- Fixture Time: 6 hours.- High Bond Strength: Provides strong, durable bonds with high shear, peel, and impact resistance.- Environmental Resistance: Good resistance to moisture, temperature variations, UV exposure, and chemicals.- Low Shrinkage: Ensures precise bonding and dimensional stability.- Gap-Filling Ability: Can accommodate irregular surfaces.

Surface Compatibility

- Polypropylene (PP)- Polyethylene (PE, LDPE, HDPE)- Other Polyolefins- ABS- Acrylic- Nylon- Stainless Steel- Aluminum- Other Metals- FRP (Fiber Reinforced Plastic)- Composites- Thermoplastic Elastomers

Comparison Note

SCIGRIP SG400LSE offers comparable results to 3M DP-8005 and DP-8010, but is often more competitively priced. Compared to epoxies, MMA adhesives like SG400LSE provide greater flexibility and toughness, making them less brittle and more resistant to impact and vibration. They also tolerate slight mix inaccuracies better and are generally easier to use in fast-paced production environments.
