Using Swiss imported brand DM adhesive for plastic bonding is not wrong. There are plastic specific quick drying adhesives such as DM5925 and DM5923, and structural adhesives such as DM1665 for bonding plastic. Click to apply for trial (limited to the top 20 candidates per day)
How to choose a good adhesive for plastic bonding
1. Before choosing glue, it is necessary to first determine what plastic material is used for bonding
The classification of plastics includes:
ABS plastic, PC, PP, PE, PET, PS, POM, PA and other plastics;
2. Determine the size of the adhesive area for surface bonding, clarify the bonding method and requirements: determine the bonding requirements, bonding speed, colloid color, colloid viscosity, high temperature resistance, bonding strength, and other requirements. For example, for large areas, slow drying glue is suitable to leave enough time for you to operate, while for small areas, instant glue is a good choice; Determine whether it is a flat adhesive. If it is a buckle adhesive or a sleeve adhesive, even if the adhesive strength is not very good, a good bonding effect can be achieved
3. Determine the specific adhesive to be used
What kind of glue is good for sticking plastic?
There are various types of adhesives to choose from for adhesive PC, and quick drying adhesives are preferred for easy operation and high efficiency. Different types of instant glue can be selected according to different requirements:
1. Fast bonding speed, impact resistance, and temperature resistance of -40-85 degrees. Widely applicable, it has good bonding effect on various materials, and will not leave whitening marks after bonding PC and TPU.
2. Low whitening, medium viscosity, fast curing speed, excellent bonding effect between PC and TPU Structural adhesives are commonly used for bonding large areas of plastic. Structural adhesives have high bonding strength, long operating time, and are convenient for practical use. The structural adhesive commonly used for bonding plastics also performs very well in bonding metals. How to choose the appropriate adhesive to achieve product bonding, leak repair, sealing or other purposes?
To choose the appropriate adhesive, two points must be determined first:
Requirements for the material and bonding process of the adhered substance. Simply put, it means sticking something? What are the requirements after sticking? Many adhesives are universal, such as plastic, metal, rubber, and other adhesives. For example, the commonly used 502 adhesive in daily life can stick anything, but it doesn’t stick very well or strongly. Therefore, when choosing the appropriate adhesive, the following principles should be followed:
1. Consider the types, properties, sizes, and hardness of bonding materials;
(1) Metal: After surface treatment, the oxide film on the metal surface is easy to bond; Due to the significant difference in the coefficient of expansion between the two phases of the adhesive bonding metal, the adhesive layer is prone to internal stress In addition, the metal bonding area is prone to electrochemical corrosion due to water action.
(2) Rubber: The greater the polarity of rubber, the better the bonding effect. Among them, nitrile chloroprene rubber has high polarity and strong bonding strength; Natural rubber, silicone rubber, and isobutylene rubber have low polarity and weak adhesion. In addition, there are often release agents or other free additives on the surface of rubber, which hinder the bonding effect.
(3) Wood: It is a porous material that is prone to moisture absorption, causing dimensional changes and potentially leading to stress concentration. In addition, polished materials have better bonding performance than rough surface wood.
(4) Plastic: Polarized plastics have good bonding properties.
(5) Glass: The surface of glass is composed of countless uniformly uneven parts from a microscopic perspective. Use adhesive with good wetting properties to prevent the possible influence of bubbles in concave and convex areas.

Instructions for using plastic adhesive:
1. Clean the surface of the plastic bonding interface to remove dust and oil stains from the bonding interface;
2. Apply the adhesive plastic evenly onto the bonding surface and fix the two bonding substrates together;
3. Place the bonded substrate in air for natural curing, and curing for 24 hours can achieve the effect of tearing and tearing the material without delamination. Reminder: Unused glue cannot be poured back. Please seal and store it to prevent the quality of the glue from deteriorating;
