How to solve the whitening phenomenon during the quick drying adhesive operation?
Fast drying adhesive material is very wide, can be bonded to plastic, metal, glass, wood, ceramic, rubber, stone, paper and so on.
For many other glue bonding materials, such as PP, PET, PE, TPU nylon, fluorine rubber should be used special glue. If you still want to use quick-drying adhesive, you need special treating agent to do surface treatment, because these materials are inert materials, poor activity, need to enhance the activity to bond well, the treatment of these materials, 770,778,788 treatment agent, the effect will be better.
Some customers also report that the quick-drying glue is easy to turn white and fog, especially the bonding of black plastic, which greatly affects the appearance of the product. Such problems as quick-drying glue are very common, because the quick-drying glue is cured by moisture in the air. If the air is not circulated, the white fog in the curing reaction is not easy to disperse and will gather around the bonding surface. (Which glue is special adhesive PP, PET, PE, TPU nylon --loctite401-454-4860-4850).
Problem solving method:
First, be sure to use the original authentic glue, keep the period as fresh as possible.
Second, use a low-bleaching quick-drying glue, like loctite460, but it's more expensive than regular quick-drying glue,
Third, the use of quick-drying adhesive accelerator,712 to speed up the reaction of quick-drying adhesive, avoid the production of white fog,
Fourth, increase ventilation in the operation workshop, and package the glue after it is completely cured.
Note:
1. Keep the air dry and ventilated. Operate in a damp and cool environment.
2, control the amount of glue, try not to make too much glue, glue does not flow out, in the bonding surface is not visible whitening. It is beautiful and reduces the consumption, thus reducing the cost. Kill three birds with one stone.
3, choose different glues according to the different materials. This is often said true sex, can not be confused with glue.
Of course, the strength is related to the quality of the glue and the adhesive material, such as silicone, with fast drying glue is impossible to glue directly, must be treated with professional treatment agent, silicone and then use fast drying adhesive effect is very significant.
