Some PET release films refer to tapes. Masking tape and high temperature masking tape Performance parameters: substrate thickness mm Tensile strength n/cm Crepe paper 0.15>80 Masking paper is a high-tech decoration and spraying paper, widely used in interior decoration, household appliances spray paint and luxury car spray. Copper-aluminum foil tape is used to wrap the steam conduit to prevent the temperature from dissipating to the outside. Application and description of non-conductive copper foil tape: Replacing enameled wire and various types of transformer shielding. The golden finger tape is made of polyimide film and coated with high temperature resistant silica gel. The color is brown (amber). Residual glue, the product has excellent electrical properties. Why can't it stick? Some tapes are sticky to the touch, and the sealing effect is not good. They always open by themselves. Is there a good gold finger tape of the same quality?

  This is the problem of glue, which is very sticky when touched by hand. The initial adhesion is good, and it jumps off after adhesion, but the adhesion is poor. The initial adhesion is inversely proportional to the adhesion retention, which means that if the adhesive gold finger tape is touched by hand, the adhesion retention will be poor.

  We generally use PET release film with high solid content and good viscosity. The general solid content commonly used on the market is around 50. If the viscosity is good, it is better to use 52 solid content. But the price may affect the difference of 200 yuan a ton. There is also a social relationship between the thickness of the glue. Generally, the thickness of the glue is about 20-22. The thinner the coating, the worse the viscosity, but not the thicker the coating, the better the viscosity will be. The drying temperature depends on the actual work operation, and also has a certain relationship with the operation and development speed of the machinery and equipment.

  Generally, gold finger tape is coated with water glue. It has poor initial adhesion and stickiness. Its bigger feature is the cheap price. It is recommended not to use too tight, as the film will be stretched so that the glue will rebound when it is not sticky enough. In addition, the case can be back-sealed with scissors or by scraping the pressure seal under the back-sealing with a paper cutter. Stick the tape to the paper so it doesn't break.

  In winter, because the temperature is relatively low, the viscosity of the glue will be relatively poor, you can replace it with oily glue, thicken the glue layer, or put the tape in the greenhouse.
