It is milky products, not literal understanding of transparent color, mainly used in the paper surface piercing after patching paper surface can also write (transparent tape does not work), not much of a trace, and copying no shadow. The invisible tape technology parameters: Characteristics: tack uniform and stable, no residue and traces of tape surface can be written easily deconvolution can Shousi. Uses: resin lens injection molding, printed materials testing, printed circuit board surface printing fastness test, screen printing, pad printing, the bronzing surface fastness testing, painting, electrical the crossing surface fastness test, production, packaging positioning. Specifications: 12.7mm * 33m, 19mm * 33m 12.7 * 66m, 19mm * 66m, 25.4mm * 66m adapt to industry: animation of the original painting, spectacle lenses, electronic manufacturing, consumer products, toys, gifts manufacture and packaging, plastic products, metal products manufacturing and packaging, advertising production, the garment industry. Application: Scotch magic invisible tape, widely used in the screen printing color printing. Printing process. Test ink adhesion, the standard testing methods.: PCB plastic products screen printing silk screen printing electronic products. Printing test plastic characteristics: viscosity stability. paste strength, high transparency of the international standard test tape. falling into the same Huangdu Li carton packaging. easy to save office specifications, and easy-to-use usage dumped oil test method: 1. Objective: Assessment of the product paint coating adhesion. 2: fuel injection / printing / hot stamping / screen printing part. 3. Equipment: 3M810 tape, Jiedao, 4. Procedures: 4.1. Before the test must make sure that the surface of the coat of paint is completely dry. 4.2 Jiedao painted surfaces to quit apart as 11 1/16 "parallel lines 11 and then the vertical ring into the same parallel line does not hurt the plastic pieces (ring broken paint coating as a standard). 4.3. Gum test paper affixed to nicks surface (tape at both ends should grow scored 1/2 "long, so that bit up) adhesive tape so that the internal air / 90 ± 30 seconds and keep pressed with a finger. 4.4 to pull up the tape parallel to the surface of the paint coating 180 ° angle. Judgment: 5.1 off oil more than 10% of the number of cells as a serious problem. 5.2 off the oil cell number more than 5% of the general problem.
