The difference between glue without base material and glue with base material

Double-sided tape is an important material used in polydome, so what should you pay attention to when using double-sided tape? The metal dome needs to be fixed on the circuit board in the polydome, so different steps require different double-sided tape.

Introduction to double-sided tape without base material

No base material means that the double-sided tape does not have any media and is produced directly from the tape. The outside is in polymer-coated waterproof kraft paper. This tape is transparent in color and has good bonding ability, which can effectively prevent it from falling off. However, since double-sided tape without a base material is fluid, it needs to be laid flat when stored. If it is placed upright, the glue will overflow from both sides.

With base material double-sided tape

Double-sided tape with a base material is mainly made of tissue paper, PET, PVC film, non-woven fabric, foam, acrylic foam, etc., and is coated on both sides with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive, acrylic Pressure-sensitive adhesive, etc. A roll-shaped or sheet-shaped adhesive tape is made on the above-mentioned base material, and is partially composed of a base material, an adhesive, and a release paper.

Comparing double-sided tape with a base material and without a base material, double-sided tape with a base material has a base material in the middle, which allows the glue to maintain its shape and can be stored upright without the glue flowing out from both sides. Double-sided tape without a base material only has an adhesive film, so to achieve the same bonding performance, the total thickness of the adhesive is smaller, softer and more conformable. The disadvantage is that when the ambient temperature is relatively high, the adhesive layer will have end faces. Glue overflow. When using double-sided tape with a base material, it is necessary to discharge the gas from the sticky surface so that the double-sided tape can fully contact the object and stick firmly. When used incorrectly and the double-sided tape needs to be torn off, the double-sided tape with a base material will not come off and is easy to use.

The double-sided tape in the polydome plays a very important role as it plays a key role in connection and is also waterproof. Due to the use of high-quality materials, 3M double-sided tape has stable performance and strong fixing ability during the application process of polydome.
