When the PE protection film is used, the problem of non sticky adhesive is often encountered. The adhesive non stick will cause the protection film to warp, fall off, and not stick to the above problems. It seriously affects the quality of the product, which not only causes the cost waste of the protective film, but also affects the production and use of the products. The reasons for the production are summarized as follows:

1, the first thing to be determined is whether the situation is related to the quality of the adhesive itself, and if necessary, the adhesive must be replaced.

2, we can appropriately reduce the total content of water and alcohol in ethyl acetate in the configuration, or to replace a better quality ethyl acetate. The best ethyl acetate for the suitable adhesive is to total the total content of water and alcohols under the total amount of less than 0.2%.

3, when the PE protective film of a compound moisture absorption is encountered, the curing agent should be adjusted to a ratio of about 5%-10%, and should not be used at the same time to use the film with the tide.

4, to control the complex environment of PE protection film, we can strengthen indoor air convection, such as placing fan and so on, but can not blow to the PE protective film composite machine. In addition to the compound, pay attention to the scrapers and guide rolls near the rubber grooves at any time. If there is no water droplets, the speed should be reduced synchronously.

5, to shorten the storage time of the prepared adhesive, and then reduce the amount of preparation by reducing the amount of preparation to shorten the storage time in the preparation of the adhesive, and then to increase the drying temperature can reduce the amount of residual solvent, which can also reduce the effect of water and alcohols on the curing agent.
