3M 7000047442 Glass Cloth Tape 361 White 1in X 60yd 7.5 Mil

Product Description

The 3M 7000047442 is a white glass cloth tape with a silicone adhesive system, sold as a 1-inch-wide by 60-yard roll at 7.5 mil total thickness. It is engineered for applications that demand sustained high-temperature resistance, strong adhesion, and an abrasion-resistant backing. The woven glass cloth construction provides dimensional stability under heat and mechanical stress. Silicone adhesive maintains bond integrity at elevated temperatures where acrylic or rubber-based adhesives fail. HVAC technicians, industrial maintenance crews, and specialty coatings applicators are the primary installers and users of this tape.

This tape is commonly used as masking protection during thermal spray operations, where high heat and abrasive particulates would damage or lift conventional tapes. It is also suited for high-temperature bundling, wrapping, and insulation applications in industrial, aerospace, and commercial HVAC environments. The tape can be certified to meet F.A.R. 25.853, the flame-resistant specification relevant to aircraft interior materials, making it applicable in aerospace maintenance and fabrication contexts.

Key Features

• 7.5 mil total thickness for a robust, abrasion-resistant backing
• Silicone adhesive system rated for high-temperature service
• Woven glass cloth backing resists tearing and dimensional distortion under heat
• Suitable for masking in thermal spray operations
• Can be certified to F.A.R. 25.853 flame-resistant specification
• White color aids visual inspection and contrast in masking applications

Compatibility

Designed for high-temperature masking, bundling, and insulation applications across industrial, HVAC, and aerospace maintenance environments where silicone adhesive and glass cloth construction are required.

Installation Notes

Application of glass cloth tape is typically performed by industrial maintenance technicians, HVAC installers, or aerospace maintenance personnel following site-specific procedures. Surfaces should be clean, dry, and free of oils or contaminants before tape application to ensure full adhesive contact. When used in thermal spray masking, confirm tape edges are firmly pressed down to prevent overspray penetration. Remove tape promptly after the process is complete to prevent adhesive residue buildup at elevated temperatures.
