3M 7010309733 Thermal Bonding Film 3 Mil 4in X 72yd

Product Description

The 3M 7010309733 is an unsupported, thermosetting film adhesive engineered for structural bonding of metals and glass. Supplied in a 4-inch by 72-yard roll at 3 mil thickness, this film adhesive delivers high shear, peel, and cleavage strengths across a wide temperature range. It cures in as little as 30 seconds at 450 degrees F, producing a tough, flexible bond. The film carries high uncured strength, is lightweight, and handles easily on the bench. Low tack and low flow characteristics give technicians precise control during positioning before cure. Licensed applicators and fabrication specialists working with metal assemblies and glass bonding applications are the primary installers.

This thermal bonding film is suited for structural adhesive applications in industrial, commercial, and specialty fabrication environments. Typical uses include metal-to-metal bonding, metal-to-glass lamination, and assemblies where a clear, film-based adhesive is preferred over liquid or paste alternatives. The film format is well suited for flat or contoured surfaces where consistent bondline thickness is required. It performs across a wide temperature range, making it appropriate for assemblies exposed to thermal cycling in service.

Key Features

• Unsupported thermosetting film — no carrier layer to remove, consistent 3 mil bondline thickness
• Excellent adhesion to metal and glass substrates
• High shear, peel, and cleavage strength over a wide service temperature range
• Fast cure: achieves a tough, flexible bond in as little as 30 seconds at 450 degrees F
• High degree of film clarity when in contact with a solid surface
• Low tack and low flow allow precise part positioning before cure
• Lightweight and easy to handle; compatible with relatively low bonding pressures

Compatibility

Designed for structural bonding of metal and glass surfaces. Consult surface preparation and cure parameter guidelines to confirm suitability for specific substrate combinations and end-use conditions.

Installation Notes

Application is typically performed by fabricators, glaziers, or industrial assembly technicians experienced with film adhesives. Surfaces should be clean, dry, and free of oils or contaminants before film is applied. Follow the cure schedule appropriate for the substrate and press equipment — do not substitute cure temperature or pressure without validating bond performance. Handle unprocessed film rolls away from heat sources and open flames, as cure initiates at elevated temperature.
