3M 7100200228 Polyurethane Sealant 540 White 50 Gal Drum

Product Description

The 3M 7100200228 is a one-component, moisture-curing polyurethane sealant that forms permanently elastic bonds across a wide range of substrates. Sold in a 50-gallon open head lined drum, this product is well suited for high-volume sealing and bonding applications in industrial, manufacturing, and construction environments. The sealant cures on exposure to ambient moisture and remains flexible after cure, allowing it to accommodate joint movement and thermal expansion without cracking or losing adhesion. Tradespeople and production line operators working with mixed-material assemblies will find this format practical for bulk dispensing applications.

This sealant is designed for use on plastics, fiberglass-reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal, and wood. The 50-gallon drum format is intended for commercial or industrial settings where repeated, large-scale application is required, such as vehicle assembly, panel fabrication, or structural bonding lines. The white colorway suits applications where a finished appearance or color-matching to light-colored substrates is necessary.

Key Features

• One-component formula cures with ambient moisture — no mixing required
• Permanently elastic bond accommodates joint movement and thermal cycling
• Adheres to plastics, FRP, SMC, aluminum, steel, coated metal, and wood
• White color suitable for light-substrate or finish-visible applications
• 50-gallon open head lined drum format supports high-volume bulk dispensing

Compatibility

Designed for bonding and sealing applications involving plastics, FRP, SMC, aluminum, steel, coated metal, and wood substrates in industrial and commercial settings.

Installation Notes

Application should be performed by qualified personnel familiar with industrial sealant dispensing equipment. Ensure all substrate surfaces are clean, dry, and free of oils or loose material before applying. Follow applicable safety data sheet (SDS) guidance for ventilation and personal protective equipment when working with isocyanate-based products. Seal the drum properly after each use to prevent premature moisture cure of remaining product.
