What Is Masking Tape

Masking tape is a kind of adhesive tape that can be removed without residue. It can be used to protect part of the surface in spray painting, block paint, paint, pigment, dust, etc. It can also be used in electronic equipment to protect parts and isolate dust, static electricity, etc.

 

Masking tapes are used in automobiles, electronics, aircraft, ships, rail locomotives, construction and interior decoration and other industries. Meet the needs of various masking and protection applications, such as high temperature or medium temperature spray masking, sandblasting masking, electroplating masking, electronic equipment parts protection, household temporary fixing, etc.

 

The adhesive layer of the masking tape can be acrylic glue or rubber glue. The performance requires that the glue has strong cohesion and good initial adhesion. After the masking tape is used, it can be easily peeled off from the substrate without damaging the substrate or leaving a glue residue.

 

 

Generally speaking, the structure of masking tape is divided into four layers:

 

1. The top layer is the anti-sticking layer of the back material, which is convenient for tape unwinding.

 

2. The second layer is the backing material, which provides the physical properties of the tape structure.

 

3. The third layer is the primer treatment layer, which is used to increase the adhesion of the adhesive to the backing material and avoid residual glue.

 

4. The bottom layer is the adhesive layer, which provides bonding to the adhered surface and is also a very important part of the tape structure.

 

Features of masking tape

 

1. When using, the substrate is easy to tear by hand, and it is the basic requirement of masking tape that no knife is needed. This helps to improve the work efficiency during the construction process, especially the PE woven fabric as the base of the health tape and cloth tape, the special longitudinal fine fiber weaving process, the hand tearing surface is neat.

 

2. Good conformability is another requirement for the substrate. The substrate is light, thin and soft, and can be completely attached to the surface of the masked substrate without leaving any gaps. During the spraying or construction process, the corrosive liquid cannot penetrate the masking tape to ensure the masking effect.

 

3. The side edge of the adhesive layer has a good effect, remove the tape after masking, and the side edge is straight.

 

4. The adhesive layer has strong cohesion, and tearing without residual adhesive is the most important performance. The special adhesive of the masking tape requires good initial viscosity, and the paste is firm and does not warp during construction. After 1-4 weeks of curing after construction, the masking tape is torn off, leaving no glue residue on the masked surface. This is also an effect that ordinary cheap tape cannot meet, and only high-quality glue can meet the requirements.

 

Application of masking tape

 

Masking tape can protect the surface of parts, block paint, coatings, pigments, dust, etc. in the process of painting and coating. It can also be used in electronic equipment to protect parts, isolate dust, static electricity, etc. tesa masking tape can meet most of needs for industry sheltering and protection. It is widely used in automobiles, electronics, aircraft, ships, rail locomotives, construction and interior decoration, and other industries.
