It is made of BOPP biaxially oriented polypropylene film as the base material, and is evenly coated with acrylic pressure-sensitive adhesive latex after heating.
The stickiness of sealing tape mainly comes from the adhesive component in its glue. Over time, the glue will gradually age. In this process, the molecular structure of the adhesive may change, resulting in a decrease in its stickiness.
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.
