Double Sided Tape For Glass And Metal
OPALUS PACK is a manufacturer of double sided tape for glass and metal applications where a clean bond line, stable holding, and surface preparation must be checked together. It is used for glass panel to metal frame bonding, stainless steel trim attachment, aluminum edge fixing, and coated metal assemblies. Its acrylic foam structure helps absorb small stress between rigid glass and metal parts that may expand or vibrate during use.
- Material: acrylic foam with acrylic pressure-sensitive adhesive
- Colors: clear, gray, black
- Thickness: 0.4 mm, 0.8 mm, 1.0 mm, 1.5 mm
- Width: slit rolls from 6 mm to 600 mm
- Liner: red PE film or release paper
- Supply form: rolls, strips, die-cut parts
Key Features of Our China Acrylic Double Sided Tape
Product Overview
Glass and metal are both smooth, but they fail in different ways. Glass may look clean while still holding fingerprints, moisture, detergent residue, or fine dust near the bonding edge. Metal may carry oil, cutting fluid, oxide film, weak paint, or loose powder coating. If adhesive contacts these unstable layers instead of the real surface, the bond may look fine at first and then lift after heat, load, or humidity.
This glass-to-metal bonding tape is made for glass, stainless steel, aluminum, painted metal, and selected powder-coated metal. In sample checks, cleaned stainless steel showed faster adhesive wet-out than oily stainless steel under the same roller pressure. Clear 0.8 mm tape gave a cleaner transparent bond line on glass edge samples, while gray 1.1 mm tape seated better on slightly uneven aluminum frames. For powder-coated metal, a small adhesion check is useful because coating failure may occur before adhesive failure.
Benefits
- Bonds glass panels to metal frames without visible drilling points.
- Helps reduce stress from temperature movement between rigid surfaces.
- Clear tape gives a cleaner look near visible glass edges.
- Gray and black tape hide well behind metal frames or tinted glass.
- 0.8 mm to 1.5 mm options handle small gaps and frame tolerance.
- Firm roller pressure improves wet-out and reduces edge lifting risk.
Which Thickness and Color Work Better for Glass-to-Metal Bonding?
Thickness should follow the real contact condition, not only expected holding force. For flat glass and smooth stainless steel, 0.4 mm to 0.8 mm keeps the bond line lower. For aluminum frames with coating texture, step difference, or assembly tolerance, 1.0 mm to 1.5 mm is often safer because the foam layer can conform under pressure. Clear tape is better where adhesive may be seen through glass. Gray tape works behind metal frames, while black tape suits tinted glass, dark frames, and display edge bonding.

How Should Glass and Metal Surfaces Be Prepared Before Bonding?
A reliable bond starts before tape application. Glass should be wiped to remove fingerprints, moisture, detergent residue, and dust. Metal should be checked for oil, oxide, weak coating, and loose particles. Oily metal should be degreased before final alcohol-water cleaning. If light abrasion is used on oxidized metal, clean the surface again afterward. Apply the tape to one side first, avoid touching the adhesive, and press with even roller pressure. In factory observations, insufficient pressure caused partial wet-out and edge lifting near glass edges and coated metal corners.
FAQ
Is this tape suitable for bonding glass to stainless steel?
Yes. It is suitable when both surfaces are clean, dry, and firmly pressed. For oily stainless steel, degreasing and a sample test are recommended.
Should I choose clear, gray, or black tape?
Choose clear tape for visible glass edges, gray tape for hidden metal frames, and black tape for tinted glass, dark frames, or light-blocking areas.
How long should the bond rest before loading?
Light handling can be checked earlier, but full bond development is typically evaluated after about 72 hours at room condition.
Why does tape sometimes fail on glass and metal?
Common causes include glass moisture, metal oil, oxide film, weak powder coating, wrong thickness, low application temperature, poor roller pressure, or early loading.
