The sandblasting protective film refers to a special type of adhesive tape used for the protection of art glass during the sandblasting process, which involves sculpting with abrasive grit, such as silicon carbide. There are generally two types of sandblasting protective films: one is with an oil-based adhesive without a release paper backing, and the other is with a water-based adhesive with a release paper backing. Both types consist of three components: release paper coated with silicone, adhesive (either oil-based or water-based), and a PVC plastic face film.
The sandblasting protective film specifically designed for stone is suitable for the engraving of marble, ceramic tiles, and tombstones, etc. It exhibits strong resistance to impacts and has good adhesive properties. The water-based adhesive composite protective film is primarily used for sandblasting engraving on art glass and for protecting the surface of other items. The water-based adhesive, also known as the polyvinyl acetate series, is non-toxic and harmless to the human body, complying with national environmental protection regulations.
The criteria for the film include: (1) No glue should be left behind. After the glass processing is complete, when the sandblasting protective film is removed, no traces of glue should remain on the surface of the finished glass product to maintain its cleanliness and aesthetic appeal. (2) Strong toughness is needed. The film should be able to withstand the impact force of the abrasive grit, which can range from 6 to 8 kilograms, otherwise, it could puncture the protective film and damage the object being processed. (3) Proper adhesiveness is required. The film should adhere snugly and steadfastly to the glass while also being able to be smoothly removed after sandblasting is done without becoming brittle, tearing, and causing unnecessary trouble. (4) Compatibility with computer engraving. Computer engraving can save time and labor and is a high-tech trend. This requires the sandblasting protective film to have a release paper backing of certain thickness that is easy to separate.
The color and specifications of the sandblasting protective film can be customized according to the user's requirements. Common colors are white and light yellow, with typical widths of 45, 60, and 90 centimeters, and the length is measured in meters, tailored to the user's requirements.
Product Specifications: Outer dimensions: (150-2100) mm x (200-1000) m x (0.02-0.20) mm [width * length * thickness]. Peel strength: 30 – 300g/25mm (customizable according to the specific condition of the material surface).
Color options: Clear, yellow, and can also be customized according to the client's style or sample. Up to four colors of text and patterns can be printed.
