SCIGRIP SG400LSE Low Surface Energy Methacrylate Adhesive

SCIGRIP SG400LSE Structural Adhesive for Low Surface Energy Plastics and Metals

SCIGRIP SG400LSE is a high-strength structural adhesive formulated for bonding low surface energy plastics without primers or surface preparation. It bonds polypropylene (PP), polyethylene (PE), and other difficult-to-bond substrates while also allowing them to be joined to metals, plastics, and composites. Designed for manufacturing, assembly, fabrication, and transportation applications, SG400LSE provides a versatile solution for bonding similar and dissimilar materials.

SG400LSE Features and Benefits

• Bonds Low Surface Energy Plastics: Designed for bonding difficult substrates such as polypropylene (PP) and polyethylene (PE).
• No Surface Preparation Required: Bonds polypropylene without primers, flaming, plasma treatment, or other surface preparation methods.
• Bonds Dissimilar Materials: Joins low surface energy plastics to other plastics, composites, and metals for versatile assembly applications.
• Fast Working Time: Provides a 1–3 minute working time with a 6-hour fixture time.
• Non-Sag Application: Resists sagging during application, including on vertical surfaces.
