What glue can stick metal and plastic together?

What adhesives can bond metal to plastic? This question is a little biased. Plastics mainly include PC plastics, PA plastics, plastic dispensing needles, PE plastics, etc. There are many kinds of metals, such as gold, silver, copper, iron, aluminum and so on. For the bonding of plastics, it is generally easy to choose, and the requirements are not high, but metal bonding is not so simple. Metals are divided into active metals and inactive metals. If it is inactive metals, the bonding will be limited.

At present, there are many kinds of glue sold in the market. Different types of glue have different application ranges. There are also many kinds of glue that can be used to stick metal and plastic. Let's introduce which glue can be used to stick metal and plastic glue.

If cemented, general plastics are monomer raw materials, also known as resin, which are widely used. The proportion of total resin in plastics is 40% - 100%. Generally, Leto quick drying adhesive, Leto epoxy adhesive and Leto silica gel are used to bond plastics. However, some external factors must be considered before bonding, such as the size of the bonding surface, whether it should be resistant to high temperature, whether it should be waterproof and so on

Metal is a substance that is easy to conduct electricity and has good ductility. Metal materials include alloy and pure gold. Most metals are active metals. Generally, there are no special requirements for metal bonding. Quick drying adhesive, epoxy adhesive and silica gel can be used. If it is non living metal, anaerobic adhesive can be bonded, but primer must be added.

Other precautions

1. When using glue, it is inevitable that the glue will stick to the hand. Once the glue of plastic dispensing needle sticks to the hand, it needs to be handled in time. If the glue is not completely dry, you can put your hand in a cold water basin and wash the glue in about 5 minutes.

2. If the glue on your hand is dry, you need to put your hand in a warm basin and wash the glue after a period of time.

Usually, what glue can stick metal and plastic together. The plastic dispensing needle is not affected by other external factors. Fast drying, epoxy, anaerobic and UV can combine metal and plastic.
