Universal silicone sealants: types and application

Previously, for sealing seams and installation work, experts used putty of various kinds. Now they are replaced by silicone sealants. The emergence of a new product on the market has greatly facilitated the work. Modern stores offer customers a huge variety of products, differing in composition and purpose. Consider the universal sealants in more detail.

The qualitative composition has an excellent indicator of resistance to light and precipitation. It is worth noting the high adhesion. The name of the universal product was due to a wide range of uses. Sealants are often used for small repairs at home.

The consistency is viscous, elastic and dense mass.which is ideal not only for the overlap of the joints, but also for gluing surfaces of various materials, for minor installation work.

Various components are used in the production of silicone blends. Each element performs a specific purpose.

Universal sealants are complex mixtures.

• The main component of the product is silicone rubber.
• Excellent viscosity and strength is achieved through the use of an amplifier. The element is "turned on" after the layer has dried.
• The primer of adhesion is responsible for reliable and durable adhesion of the compound to the base.
• Elasticity and practicality are carried out by a silicone plasticizer.
• During the process of freezing products responsible vulcanizer. Thanks to him, the pasty product becomes a rubber substance.

Additional elements are also used, such as mechanical fillers, dyes and fungicides.

Products represented by foreign and domestic manufacturers, is divided into two types: one-component and two-component sealants. The first variety has a wider range of uses.

Consider the types of one-component compositions.

• Alkaline material is a separate product segment. The main feature is that manufacturers use amines as a basic element.
• Acid. Acetic acid is present in the sealant. This component has a sharp odor that is strongly felt when used. The product has an affordable price, however it is incompatible with some metals.
• Neutral. For the manufacture of the material is used alcohol or ketoxime. The composition does not conflict with different types of surfaces.

Silicone sealant has excellent elasticity, due to which the composition can be used on moving parts if necessary. A quality product, made in accordance with the standards of GOST or European standards, has high strength.

Universal formulations are not exposed to ultraviolet radiation and household cleaning elements. Another feature of the product - excellent heat resistance. The operational characteristics of the layer are preserved as with minus,and high temperature: from -50 degrees to 300 degrees Celsius (depending on the type of product, manufacturer and other features).

The experts have compiled a number of advantages and disadvantages of universal silicone compounds, taking into account product characteristics and reviews.

Pros:

• convenient and practical use;
• resistance to UV radiation and negative external effects;
• excellent adhesion to various materials;
• resistance to chemical elements;
• tolerance of sudden temperature changes;
• reliable protection of joints from germs, bacteria, mold and fungus;
• affordable price;
• wide scope of application.

Minuses:

• the need for thorough surface preparation before using sealant;
• Some formulations are not compatible with conventional dyes.

A wide range of products of both domestic and foreign production is available to the Russian consumer. More focus on the most popular and demanded compositions.

This is a universal white compound, related to the segment - acidic compounds.Silicone waterproof sealant can be used to work both inside and outside the room.

Specifications:

• manufacturing country - Russia;
• 260 ml cartridge;
• scope of use - repair and construction work.

Universal sealant Hauser UNI is ideal for home repairs. Experts claim that the composition is ideal for work in construction. The main scope of application: protection of polyurethane foam from direct sunlight, as well as sealing joints at window frames and doorways.

Performance characteristics:
