Masking tape is widely used in electronic components, automotive industry spray paint masking, various industries and construction decoration industries such as pasting, protection, fixing and sealing packaging, etc., almost all walks of life can not do without it.
There are many types of masking tape on the market today, and the requirements for masking paper are different according to the requirements of use and the environment of use. Generally according to its performance, it can be divided into low temperature masking tape, medium temperature masking tape, high temperature masking tape and so on. According to different uses, the depth and fineness of the paper wrinkles will vary.
In the process of sourcing masking tape, we often encounter all kinds of masking tape, which dazzles us, and some inferior masking tapes are easy to be broken, seepage, residual glue and It is easy to warp and other problems during use.
Since the price of masking tape is generally more expensive, how to choose masking tape?
Take a look: The masking paper used to make masking tape has good humidity and solvent resistance, but also has impermeability and absorption. Not only the paper needs to be flexible, but also needs to be temperature-resistant, so beautiful Textured paper tape must be uniform in color, no variegated color, or color superimposition, and there is no glue leakage on the back, no glue residue, and no wrinkles on the paper.
Two pull: Masking tape requires good elongation and high tensile strength, so a good masking tape not only does not have the phenomenon that it cannot be pulled, but it is also not easy to be broken.
Three shakes: Masking tape requires a strong unwinding force, so it shakes when it is pulled, and it won’t slide down like a yo-yo.
Four touches: Masking paper requires very high initial adhesion and retention. You can use masking tape to stick on the surface of the object, and then quickly pull it apart for testing. Check if you have repeated pasting several times, then touch it with your hands. See if the stickiness of the tape has decreased.
Five smells: The glue used to make masking tape is not allowed to be adulterated. When some bad manufacturers make glue formulations, in order to save costs, they will use gasoline and acid to dissolve them, so the smell of the tape is very Large, regular large enterprises use toluene to dissolve, and it has been volatilized by the fan during the coating process, so there is no very pungent smell.
