Description
tesa 4970 12mm mounting tape 4970 is a white, double-sided mounting tape made with a PVC film backing and tackified acrylic adhesive. This 12 mm width creates a narrow, controlled bond line for trims, signs, scales, displays, and assembled parts. High initial tack gives the laminated joint immediate handling functionality, while the conformable backing helps the adhesive contact rougher or lightly dusty surfaces.
Where tesa 4970 12mm mounting tape 4970 Is Used
The product is suited to long-term mounting of plastic and wooden trims, decorative point-of-sale materials, signs, scales, and furniture moldings. It can replace clips, liquid adhesive, or visible fasteners when the design provides enough bonded area and both surfaces are compatible. The 12 mm format is useful on narrow flanges and profiles where a wider tape would need trimming or could remain visible at the edge.
Bond quality depends on actual surface energy, texture, cleanliness, stiffness, load direction, and service environment. The tackified acrylic adhesive can bond many low surface energy materials, but every production application should be tested on the real substrates. Peel loading, sustained weight, heat, plasticizers, humidity, and contamination can change performance. Use mechanical retention where the assembly or safety requirement calls for it.
How tesa 4970 12mm mounting tape 4970 Handles
Clean and dry both surfaces, cut the tape to length, and apply it without stretching the PVC carrier. Press firmly across the entire strip to create intimate adhesive contact, then remove the liner and join the second part in its final position. The strong initial tack limits repositioning, so fixtures or alignment marks help on long trims and display graphics.
The product information gives a total tape thickness of 225 micrometers, a white PVC film backing, and a tackified acrylic adhesive. Initial adhesion to steel is listed at 13 N/cm in current product data. The tape also provides light and aging resistance, plasticizer resistance, and good conformability. These figures are representative technical values, so qualification on the intended materials and load remains part of the assembly process.
Plan the tape path so it supports the load continuously and avoids sharp corners where stress can concentrate. Rounded ends and full-width pressure help reduce lifting at exposed edges. When joining flexible trim to a rigid panel, allow the trim to relax before taping so stored tension does not pull against the adhesive. For outdoor or high-temperature service, test aged samples as well as newly assembled parts. A successful initial bond does not replace validation of long-term creep, peel, and environmental exposure. Document surface preparation, application pressure, and test conditions so approved assembly settings can be repeated consistently on the production floor.
