3M 7000048420 Double Coated Tape 1 in 36 Yd Acrylic

Product Description

The 3M 7000048420 is a double coated tape built around 3M Adhesive 300, a medium-firm acrylic adhesive that bonds aggressively to a wide range of surfaces. The adhesive is applied to both sides of a 0.5 mil PET film carrier, which delivers dimensional stability and makes handling during slitting and die-cutting more consistent. A 3.2 mil densified kraft liner protects both adhesive surfaces until application. The tape measures 1 inch wide and 36 yards long with a total thickness of 3.9 mil. It is designed for bonding foams, gaskets, and plastics in manufacturing, fabrication, and assembly environments where a clean, reliable double-sided bond is required.

This tape is suited for joining smooth, thin materials that carry low residual stress. It performs well on both high-surface-energy (HSE) plastics and low-surface-energy (LSE) plastics such as polyethylene. Common applications include foam and gasket attachment, plastic-to-plastic lamination, and light-duty component assembly. The quick-flowing adhesive delivers high initial tack, which supports faster lamination cycles in production or field fabrication settings. Trade professionals in HVAC, electrical, and general mechanical trades use this tape where a thin, stable, double-coated bond is needed.

Key Features

• 3M Adhesive 300 medium-firm acrylic bonds to HSE and LSE plastics including polyethylene
• 0.5 mil PET film carrier adds dimensional stability for consistent slitting and die-cutting
• 3.2 mil densified kraft liner releases cleanly and evenly
• Quick-flowing adhesive provides high initial tack for faster lamination
• Transparent construction allows visual alignment during application
• Total tape thickness of 3.9 mil keeps bond lines thin and uniform

Compatibility

Designed for bonding foams, gaskets, HSE plastics, and LSE plastics such as polyethylene. Suitable for smooth, thin substrates with low residual stress in manufacturing and assembly applications.

Installation Notes

Surface preparation is critical — clean bonding surfaces of dust, oil, and moisture before application to achieve full adhesive contact. Apply firm, even pressure across the tape length after placement to ensure proper wet-out of the adhesive. In fabrication settings, allow adequate dwell time before subjecting the bond to load. Store unused rolls in a cool, dry environment away from direct sunlight to preserve adhesive performance.
