3M 7100039208 Instant Adhesive SF100 Clear 1 Pound

Product Description

The 3M 7100039208 Scotch-Weld Super Fast Instant Adhesive SF100 is a low-viscosity, rapid-curing cyanoacrylate adhesive supplied in a 1-pound container. It is formulated for bonding difficult substrates including plastics, rubbers, leathers, woods, cardboard, and oily or acidic surfaces where standard adhesives underperform. The clear cure color makes it suitable for visible joint lines. Technicians in manufacturing, fabrication, and maintenance applications rely on SF100 where fast fixture times and strong bond performance on contaminated or chemically challenging surfaces are required.

SF100 is well suited for production and repair environments that demand short cycle times. Its low viscosity allows it to wick into tight-fitting joints and porous substrates. Typical applications include bonding rubber seals, plastic housings, leather goods, and wood components in both shop and field settings. The formulation is effective on surfaces that may carry light oil contamination or exhibit acidic characteristics, reducing the need for extensive surface prep in many cases.

Key Features

• Low viscosity formula wicks into tight joints and porous surfaces
• Very fast cure speed supports high-speed production and quick repair workflows
• Bonds difficult substrates including plastics, rubbers, leathers, woods, and cardboard
• Effective on oily, acidic, or lightly contaminated surfaces
• Clear cure color maintains aesthetics on visible bond lines
• Supplied in a 1-pound container for production-volume use

Compatibility

Designed for bonding plastics, rubbers, leathers, woods, cardboard, and oily or acidic surfaces in industrial, fabrication, and maintenance applications.

Installation Notes

Apply using standard cyanoacrylate dispensing equipment appropriate for low-viscosity adhesives. Ensure surfaces are free of loose debris; SF100 tolerates light contamination but bond strength improves with cleaner substrates. Avoid skin contact and work in a well-ventilated area, as cyanoacrylate adhesives release vapors during cure. Store container sealed when not in use to prevent premature moisture cure.
