Silicone adhesive for metal bonding, selected according to the process, with excellent high-temperature resistance and suitable for 123
What glue can stick metal? Adhesive is a substance that can bond two objects together. Glue does not exist independently, it must be applied between two objects to exert its adhesive effect. The chemical components in glue are present in aqueous environments. The polymer in glue (vinyl acetate in white glue is a type of petroleum derivative) is in the form of circular particles, with a typical radius between 0.5 and 5 μ m. The bonding of objects is achieved by the tensile force between the polymer molecules in the adhesive. I believe people who are not very professional will not be clear about it. In fact, different silicone adhesives are selected according to different metal materials.
Adhesive for stainless steel silicone, adhesive for iron silicone, adhesive for aluminum alloy silicone, adhesive for copper silicone, adhesive for electroplated parts silicone, adhesive for hardware silicone, etc! Firstly, we need to specify which materials and metals are suitable for bonding (such as ABS bonding with metals, PVC bonding with metals, PP bonding with metals), and which metals are not suitable for silicone bonding? At present, bonding technology is not suitable for chrome plated metal bonding and silicone bonding.
1. Silicone adhesive for metal bonding is suitable for four categories based on the process: high-temperature vulcanization bonding, low-temperature compression molding, room temperature rapid bonding, and slow drying adhesive bonding. Dear customers, please choose silicone adhesive suitable for bonding metals according to different processes. When it comes to bonding silicone and metal, some people often ask, does silicone glue stick firmly to metal? How to stick it firmly? What I want to tell you here is that as long as you use the right method, DM glue from the glue manufacturer can stick well with metal. Below, the editor will introduce the detailed method to you. Silicone metal adhesive can effectively improve the surface polarity of metal materials, greatly enhancing the bonding performance. The treated metal can be used for silicone double-sided adhesive, and also has good effects on spray painting and screen printing on silicone after treatment. It has the characteristics of strong initial adhesion, high bonding strength, and easy use.
2: The operation method of quick drying silicone glue is to apply a treatment agent to the surface of the silicone gel. After about 10 seconds, the treatment agent evaporates. Apply the glue evenly to the surface of the silicone gel or aluminum alloy that needs to be bonded, and press the silicone gel firmly onto the surface of the aluminum alloy for 5 seconds! The positioning time of fast drying adhesive is about 30 seconds, and it can pull the silicone gel without delamination in 30 minutes! Silicone adhesive for metal bonding
3: The operation method of slow drying silicone adhesive is to keep the surface of silicone and aluminum alloy dry and clean, without oil stains or release agents. Apply the adhesive to the surface of aluminum alloy or silicone, scrape the adhesive evenly with a film, and attach the silicone to the surface of aluminum alloy. If there is tension on the surface of silicone, it can be fixed by pressing with a heavy object. Its advantages are high adhesive strength, transparent adhesive layer, waterproof, and can withstand high temperatures of 260 degrees. The adhesive layer is made of soft elastic material that can withstand impact.
The above is about the bonding method between silicone and aluminum alloy. The same method is used for bonding silicone to metals such as stainless steel, copper, galvanized iron, etc! matters needing attention:
1: The substrate should be cleaned thoroughly;
2: Silicone adhesive contains flammable organic solvents, and should be applied in a well ventilated and away from sources of fire;
3: Do not apply too thick adhesive, as it can easily generate bubbles;
4: The adhesive should be completely dry, otherwise it is easy to produce poor adhesion.
5: The impact of construction environment: When the humidity of the glue application environment is greater than 75%, it will cause poor bonding effect. What glue can stick metal? For more relevant information, please visit our official website http://www.aicarder.com/ consulting service
