How to deal with fast-drying glue when bonding rubber

Quick-drying glue is one of the more common glues in our industry, and it is also the better to use because it is a single component and it is more convenient to operate. However, it is convenient to return, sometimes it still needs some bonding skills. For example, if you use glue for rubber bonding, then you have some skills! How should we deal with such problems?

Quick-drying glue requires surface treatment when bonding rubber!

Everyone also knows that rubber bonding is one of the more difficult processes in the quick-drying glue bonding process. Often, we can't stick well. In order to stick better, we generally use the surface of those hard-to-stick products. Surface treatment, such as the surface treatment of rubber, is generally roughened and degreased. However, some rubbers (such as fluorine rubber, silicone rubber, etc.) need to be chemically treated or pre-coated with a layer of coupling agent. If the surface treatment of the rubber fails to meet the bonding requirements, the bonding of the rubber often fails.

Quick-drying glue is also suitable for drying when bonding rubber!

Quick-drying adhesive bonding rubber, it ca n’t work slowly, it wo n’t work fast either, so it is necessary to master the time of drying. If the time is too long, the surface will condense and lose its tackiness; if the time is too short, the solvent will remain on the surface and the bonding strength will be reduced. . For the bonding of rubber, generally used rubber-based quick-drying glues contain solvents. After the solvent-containing quick-drying glues are glued, they must be allowed to air dry for a certain period of time, usually at room temperature. Chloroprene adhesive and nitrile adhesive are left to stand for 10 to 15 minutes; polyurethane quick-drying adhesive is left to stand for 10 to 20 minutes: butyronitrile-phenol-formaldehyde glue is left to stand for 20 to 30 minutes, and closed after the solvent evaporates. The rubber-type quick-drying glue mop should be aligned at one time. Failure to do so will result in bonding failure. After closing, use a round stick or a wooden hammer to beat and flatten, to eliminate interface air, make it in close contact, and improve the bonding effect.

It is also important to determine the material when the quick-drying glue is bonded to the rubber!

Of course, the above two rules must be based on this one, that is, no matter how good you are, you must also correctly determine the specific type of rubber being adhered to, otherwise it may not be possible to analyze its bonding effect. In general, rubber is divided into two categories: natural rubber and synthetic rubber. There are many varieties of synthetic rubber. Different types of rubber use different quick-drying adhesives. Therefore, for the self-adhesion or mutual adhesion of rubber, the specific type of rubber to be adhered must be judged first. In order to choose the right quick-drying glue .

All in all, choosing quick-drying glue is also a cautious task. It is not only bold but also careful, because it is related to the quality of your products.
