Cover membrane function According to the viscosity of the important: ultra-low adhesion cover film (micro-sticky cover film), low-viscosity cover film, medium adhesion cover film, high-viscosity cover film, ultra-high adhesion cover film, they identify the scale you know?

Many die-cutting newcomers toProtective film Die-cuttingThe point of viscosity is not very clear, the viscosity unit of the cover film is g/25mm, which means that the tensile force required to pull the 25mm wide spline is a number of G, cover film

UnderAccording to the StickyThe strength of sex can be divided into micro-sticky cover film, low-viscosity cover film, medium adhesion cover film, high-viscosity cover film, ultra-high adhesion cover film.

Indeed, many moments, some suppliers say 40 grams of it is also low-viscosity, he said 3--5 is ultra-low sticky. 40 grams used to be not low-viscosity. Of course, this scale is relative, if he

OfThe scale is 50 low viscosity, which is also beyond reproach.

First, but as a rule, we feel that 10G or as follows is micro-sticky, with strong stickiness.

1, in fact, according to the viscosity is a broad point of view: 3-20g--micro-sticky, 30--low viscosity, 40--low viscosity, 50, 60 is-medium adhesion, 70--high viscosity, more than 80-high viscosity.

2, although the cover film according to the adhesion of the separate there is no domestic scale principle,Die-cutting processing plant, The cover film viscosity of the identification, is to choose more suitable for die-cutting products of the cover film, cover film

The base source of the viscosity choice is that it is sticky and appropriate. The outside of the disagreement the stickiness of the necessary differences.

3, knowledge points to learn ultra-low viscosity (that is, micro and low viscosity) 3-20g easy to use easy to tear, no residual glue signs, suitable for inorganic plates, instrumentation, display, glass lenses, plastic lenses, etc., low viscosity 30g

The adhesion is stable, the adhesion is good, then the peeling function is superior, no residual glue sign, applies to the steel mirror board, the titanium metal, the glossy plastic board, the screen printing, the nameplate and so on.

4, medium and low viscosity 40g adhesion solid, good adhesion, and then peeling function superior, no residual glue signs, applicable to furniture polaroid board, stainless steel plate, tile, cloud stone, natural stone, such as high viscosity 50-60g

The adhesion is stable, the adhesion is good, then the peeling function is superior, no residual glue sign, applies to the fine grain Scrub board and the usual refractory data outside cover and so on.

5, high viscosity 70g adhesion is stable, good adhesion, and then peeling function superior, no residual glue signs, suitable for fine-grain scrub board, aluminum plastic plate, refractory plastic plate and other ultra-high viscosity 80g above viscous high, choose

With waterborne acrylic acid as pressure-sensitive adhesive, easy to use, easy to paste easy to tear, no residual glue signs, suitable for coarse-grain aluminum plate and other difficult sticky data.

6, it is worth noting that, according to the outside and pressure differences, viscous recovery rate has been divided, as usual should be shelved sufficient time after the ability to peel the cover film can certainly be suitable for viscosity.To a certain

Outside, the choice of appropriate glue and stickiness is extremely important, the subsequent processing pace is the crux of the resolution stickiness. Subsequent processing as flat as often tortuous stamping.
