& nbsp; & nbsp; & nbsp; Products made primarily from silicone are referred to as silicone products. Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances, making it an excellent desiccant, adsorbent, and catalyst carrier. Silicone materials are becoming increasingly widely used in daily necessities. But sometimes our silicone product factory encounters some difficulties, such as the bonding problem between silicone and metal, always encountering weak adhesion, bubbles, and delamination. Today, the Ruilangda editor will analyze why your design, craftsmanship, and selection cannot stick< br />

  & nbsp; & nbsp; & nbsp; Metal that is difficult to bond with silicone can be surface treated first. There are three methods that can be selected based on the actual product:
  & nbsp; & nbsp; & nbsp; 1. Chemistry; 2. Mechanical  3. Solvent< br />


  & nbsp; & nbsp; & nbsp; The purpose of using the above methods is to roughen the metal surface and clean the surface of oil and dust< br />
 
  & nbsp; & nbsp; & nbsp; When designing products. The bonding area between metal and silicone surface should be maximized. The force method is to prevent peeling force, using shear force or tensile force. Avoid selecting scarce metals when choosing metal materials. Stainless steel, aluminum alloy, iron, hardware, galvanized nickel plating, etc. can all be bonded with silicone and have lower costs.

  & nbsp; & nbsp; & nbsp; Adhesive for bonding metal and silicone
  & nbsp; & nbsp; & nbsp; The selection of silicone and metal adhesive (glue) is quite important. Silicone and metal bonding can be divided into: room temperature fast drying, room temperature slow drying, silicone hot vulcanization molding bonding, and liquid silicone and metal bonding. Each bonding method corresponds to a different bonding process, and the corresponding specialized silicone adhesive should not be confused. The material of the metal and the bonding process determine the type of adhesive used. Commonly used are silicone and metal (stainless steel bonding, iron bonding, and aluminum bonding).

  & nbsp; & nbsp; & nbsp; HY401 instant dry adhesive product features:


  & nbsp; & nbsp; & nbsp; ① Low viscosity: suitable for bonding occasions with medium gaps< br />


  & nbsp; & nbsp; & nbsp; ② Universality: Good adhesion to various substrates< br />
 
  & nbsp; & nbsp; & nbsp; Typical uses of HY401 instant drying adhesive:


  & nbsp; & nbsp; & nbsp; Suitable for rapid bonding of most metals, plastics, or elastic materials, especially for bonding porous, acidic, and absorbent materials. For example: wood, paper, leather, or fabric. If used in combination with surface treatment agents, it is also suitable for bonding difficult to bond materials such as PVC, nylon, PP, PE, etc.
 
  & nbsp; & nbsp; & nbsp; Overall, silicone and metal can stick together. The key is to treat the metal surface and select specialized silicone and metal adhesives. In addition, special attention should be paid to the certification of food grade environmental protection for products. If you have any questions, you can consult Ruilangda's online customer service.
