For a tape supplier, all tapes are coated with pressure-sensitive adhesive on a certain substrate. Pressure-sensitive adhesive is a viscoelastic polymer. In terms of materials science, all materials will be more or less affected by oxygen, ultraviolet rays, dust, solvents, moisture, etc., so the tape manufacturer will give suggestions on the appropriate service life, storage environment and conditions, packaging specifications, etc. to maintain its quality and performance.
Masking tape plays an indispensable role in the painting process. With its unique properties, such as good adhesion, easy removal, and no residual glue, it has become a powerful assistant in the hands of spray painters. Today, let's take a deep look at the application, advantages, usage tips and precautions of masking tape in the painting process.
Foam tape is made of EVA or PE foam as the base material, with solvent-based (or hot-melt) pressure-sensitive adhesive coated on one or both sides and then coated with release paper. It has the functions of sealing and shock absorption.
It is coated with high-viscosity synthetic glue, which has strong peeling force, tensile strength, grease resistance, aging resistance, temperature resistance, waterproof and corrosion resistance. It is a high-viscosity tape with relatively large adhesion.
The health tape is based on PE and PET and coated with imported heat-resistant resin. After the coating equipment, it is put into a 150℃ oven for high-temperature plasticization to form a stable polymer pressure-sensitive adhesive layer.
There are not only the common white, yellow and colorful ones, but also various colors of yellow such as light yellow, dark yellow, orange yellow, light yellow, dark yellow, etc. Then we may wonder, which color of masking tape is of good quality!
