Plastic metal bonding UV adhesive

In the application of plastic and metal bonding, the types of adhesives include ab adhesives, instant adhesives, silicone adhesives, solvent-based adhesives, UV adhesives, etc.

But there are many kinds of plastic, each kind of plastic and metal bonding difficulty is not the same, and there is no one adhesive can all the plastic and metal stick very firmly, in order to find their own plastic adhesive metal, need to consider from many aspects.

As a UV adhesive manufacturer, AVENTK will share with you today what aspects of plastic metal bonding UV adhesive should be selected from.

(The premise of using UV adhesive to bond plastic and metal materials is that at least one of the two bonding objects can be exposed to UV light, so the following plastic metal bonding refers to transparent plastic and metal bonding.)

Select glue from these aspects

1. What kind of material is it: ABS, PVC, EVA, PC, PS and other plastics that are easy to bond, and many kinds of adhesives have good bonding effect.

But for PP, PE, nylon and other difficult to stick plastic, the effect of ordinary plastic adhesive metal UV adhesive is very poor, which needs to find uv adhesive for these materials to bond, and even need to cooperate with primer to have a better bonding effect.

2, the size of the adhesive area: a large area of plastic and metal bonding, need to have a certain amount of adhesive coating time, the selection of plastic and metal bonding adhesive to have a certain operation time.

For a small area of plastic and metal bonding, pay attention to the bonding speed, you can plastic adhesive metal UV adhesive.

3, the smoothness of the metal surface: whether electroplating and spray painting is also an important factor affecting the bonding effect, too smooth metal surface and electroplated materials, the bonding strength is difficult to meet the requirements, need to go through the hair treatment in order to achieve the ideal effect.

The surface sprayed with paint is equivalent to sticking together with paint. After a long time, the paint will fall away, and the glue will also fall away. Moreover, some water will corrod the paint and affect the bonding effect.

4, plastic and metal after the completion of the adhesive should also consider the use of the environment: the choice of UV adhesive not only to be able to stick, but also to ensure that in a long period of time will not fall off.

Because each kind of plastic metal bonding UV adhesive curing after temperature resistance, solvent resistance, acid and alkali resistance, hardness, waterproof performance is not the same.
