Where can siliconized materials be used?

Adhesion is a convenient and useful property of materials. It is considered essential for primers, paints, plasters or sealants, but sometimes it is necessary for the surface to have exactly the opposite characteristics. In this case, siliconized materials are used.

During one of the tests, the glue of the well-known German manufacturer DELO kept a truck weighing 17 tons for an hour. Excellent, but not always the desired result

What are siliconized materials

Siliconized is a material on one or both sides of which a layer of a silicone-based substance is applied. It prevents the surface from adhering to any adhesives. In addition, several more useful properties of the silicone layer can be distinguished: it does not allow moisture to pass through, ecologically safe, tolerates high and low temperatures well, does not lose its properties during prolonged storage.

Siliconized material reliably protects the adhesive surface until the moment it is needed

In what form are siliconized materials produced?

Modern manufacturers they produce siliconized materials in two types:

1. On paper. In this case, several types of paper can be used as a base:
   • offset is known as a printer, is in demand for printing books, making envelopes, notepads, notebooks and other things;
   • coated is characterized by increased whiteness and is popular for the manufacture of advertising products;
   • kraft is highly durable, in demand as a packaging;
   • synthetic is made of polyethylene or polypropylene film, has a high wear resistance, strength and moisture resistance, it is used for the manufacture of tags, labels, tourist and playing cards;
   • calendered is characterized by increased smoothness, is used for the manufacture of advertising products;
   • creped has a corrugated texture, used as packaging.

1. On a film carrier. Siliconized materials of this type are more durable and weather resistant. As in the case of a paper carrier, several known types of polymer films can be used as a base:
   • polypropylene is used in the manufacture of scotch tape;
   • polyethylene is used in the food industry;
   • kraft is highly durable, in demand as a packaging;
   • lavsan is suitable for storing substances with high adhesion;
   • metallized film is used in the manufacture of labels and in the printing industry.

Where are siliconized materials used?

There are several main areas where siliconized materials are actively used:

• In the construction industry, they are in demand in the manufacture of a number of materials: tape sealants, roll or sheet materials for soft roofing, construction tapes, heat and sound insulation. In addition, siliconized materials are used as packaging materials for mastics, bitumen and other viscous compounds with increased adhesion.

Tape sealants could not have been used without siliconized materials

• Siliconized paper has completely replaced dextrin glue, which was previously used for gluing envelopes. Mail envelopes and document bags now have self-adhesive flaps. It is enough to remove the siliconized material from their surface and the envelope or bag can be sealed.

Sealing envelopes and bags has become much more convenient

• In the food industry, the chemical neutrality and moisture-proof properties of siliconized materials are especially appreciated. They are used as packing materials.
• In the printing industry, such materials are used in the manufacture of advertising posters, displays, banners, signposts and other roll-up self-adhesive products. The same applies to any kind of self-adhesive labels.

Self-adhesive label consists of such layers.

• In the medical industry, siliconized materials are in demand in the manufacture of products with adhesive layer: diapers, wound dressings, sanitary napkins, surgical drapes, bandages, plasters and other things.

In addition, siliconized materials are used in the manufacture of road signs, holograms, stickers, composite materials and others.

Conclusion

The main advantage of siliconized materials: they significantly simplify storage and use any products that have a work surface with an adhesive layer or have high adhesion properties. This explains their widespread occurrence.
