3M Aluminum Adhesive Tape 431

• Excellent sealing properties due to good moisture shielding (water vapor diffusion)
• Combination of robust aluminum and durable adhesive allows for trouble-free long-term applications
• Low flammability (Class L)
• Good chemical resistance
• High resistance to aging and weathering
• Strong heat and light reflection

Thin soft aluminum adhesive tape with transparent adhesive for masking, sealing, heat and light reflection, masking during aluminum anodizing, and as a moisture barrier.

3M metal tapes consist of pure, high-quality metal as the backing material (e.g., soft aluminum) and an equally high-quality adhesive that meets the specific requirements. 3M metal tapes combine the excellent protective properties of metals with the ease of handling and application of adhesive tapes. The metallic backing materials are resistant to aging, temperature, solvents, and moisture, with low water vapor permeability. They can be easily processed into die-cut parts and are electrically and thermally conductive.
