Silicone characteristics

Silicon is a material that is soft, elastic, and heat-resistant that is produced through the chemical synthesis of polymers. Silicone comes in liquid, elastomer, and resin forms. However, this term generally refers to a rubber silicone, which has been firmly in use since the middle of the 20th century.

This content is both technical and culinary. Complete human harmlessness is one of its features, along with the following characteristics:

  • the ability to withstand high temperatures;
  • high elasticity, lack of crackling and cringing, flexibility;
  • resistance to water, UV radiation, oxidation;
  • inertia to the effect of microbes, mild disinfection;
  • Preservation of elasticity at temperature differences.

Silicone rubber has a legitimate place in medicine; it is used to make silicone oilcloths, nipples, membranes, springs, and many other items. A component of sealants used for aquariums and kitchen and bathroom surfaces is silicone. It’s applied in numerous fields, including electronics, equipment, and agriculture.

How to choose glue – rules

Because silicone is such a popular material, it is frequently necessary to glue silicone products together. This occurs during maintenance or when crafts, jewelry (bracelets, beads), and creative classes are being completed. Usually, silicone or cyanacrylic glue is used to join parts; these adhesives enable you to firmly glue the surface defects. The excellent adherence of this glue makes it suitable for sealing other products as well.

  • to metal;
  • to plastic;
  • to rubber.

To achieve an exceptional outcome when gluing silicone at home, select a composition that satisfies the following criteria:

  • elasticity and strength – the product creates a reliable seam, which is not damaged by vibration, mechanical exposure;
  • optimal density, the ability to penetrate inaccessible places and fill small cracks;
  • the ability to withstand high temperatures – like the material itself, glue easily tolerates heating to +300 degrees;
  • safety – when heated, the product does not release toxins;
  • Simplicity of use – packaging and the method of applying glue are convenient, available even to beginners;
  • Fast polymerization – a qualitative tool freezes in a couple of hours, the product can be put into operation in a day.

Glue must be used when working with plastic, concrete, or wood, as silicone frequently needs to be bonded with other materials. It must be considered when purchasing the composition that the silicone glue can be:

  • acidic – is cheap, but causes metal corrosion;
  • alkaline – includes silicon, is super -resistant, usually used as a special tool in extreme conditions;
  • neutral – expensive, but the highest quality, suitable for any surfaces.

It is advisable to select a universal composition if the product is being purchased for use not only with silicone but also with plastic products, crafts, repair, and sealing. You must use glue intended for external use for silicone objects found on the street. Considering the necessity of disinfection, materials containing fungicidal and antiseptic additives must be purchased. It’s advised to use specific carcasses when repairing silicone components in automobiles. Stores sell a specific high-temperature glue if the product is to be used at high temperatures.

Adhesives containing cyanacrylate are all-purpose and can adhere goods under the most demanding circumstances. Straight from the bottle, they are simple to apply to the surface. Since the compositions are one-component, non-flammable, and solvent-free, they are safe for human health. They can dependable glue heterogeneous materials, such as silicone and plastic, rubber, and metal, without compromising the joint’s strength. The money dries in a few minutes at this sufficient room temperature.

Which brands are available in stores and how is silicone glued? Klebfix, which can glue any plastic, silicone, rubber, neoprene, aluminum, and steel, is one of the most well-liked brands. The chemical foundation is ethylzianacrylate, which has a very high gap resistance. Breaking the jacket site is nearly impossible if the surface was clean. Repairing hoses, elastic bands, tubes, car gaskets, telephone covers, and other products is simple when you use this product.

An additional excellent tool is Permabond Cyanacrilat. Silicone can be used to adhere even the most challenging and varied materials to them. It is possible to apply the product automatically if gluing large areas of space is required. When glue comes into contact with even the smallest bit of moisture, it freezes.

The following items may also be used with soft silicone products:

  1. ValMexinSc38. It is produced in Germany, intended for gluing and repairing products from silicone, latex, rubber, PVC. After polymerization, the glue seam is not destroyed from the action of water, freezes in 3 minutes. This material is very economical in consumption and price.
  2. Cosmofen Ca 12. A universal remedy for silicone and other materials is also produced in Germany. The strength of the joint will be high, especially if you previously apply the primer of the same name. There is a special dispenser on the tube, so the operation is easy and comfortable.
  3. Permabond 2050. Cyanacrylate glue with instant hardening is ideal for flexible compounds. The seam will be durable, vibro -resistant.

Silicone products that can be glued

Glue can be applied to nearly any kind of silicone. They mostly fix different parts of cars and equipment. Gluing technology finds application in the medical field in various products like oilcloths and gating. Special adhesives are used in industry to repair textile industry equipment, shaft coatings, and transportation tapes.
