SILICONES, POLYURETHANES, CLEANERS, ADHESIVES
On a chemical basis, sealants are divided into several types: acrylic, silicone, bitumen, polyurethane.
Silicone is a mixed organic-inorganic polymer material (rubber) with the chemical formula [R2SiO]n, where R is an organic group such as methyl, ethyl or phenyl. It may seem strange to you, but flexible and soft silicone construction sealant is made from a strong material - silicon, which occurs in the form of quartz or sand. Polymers are made from it, which are included in the composition of silicone. Silicones have a liquid, jelly-like or solid consistency, with a variety of applications. In construction and engineering, they are popular as adhesives, lubricants or insulating compounds. Covering with this material protects the surface from the effects of harmful substances and from the penetration of moisture.
- Ability to stretch - allows the silicone to be used on movable joining sections
- Perfect adhesion index – seals joints between ceramic, glass, wood, concrete, metal, plastic elements
- Silicone is heat-resistant – it retains its protective characteristics in conditions of a large temperature range (from -50 to +300 degrees)
- Water resistance (hydrophobicity)
- Resistance to the effects of oxygen, ozone, ultraviolet rays and the effects of aggressive washing components
- High degree of strength, stiffness and insulation, good electrical insulation
- Low chemical reactivity (does not easily interact with other chemical elements and compounds)
Polyurethane is a polymer (polyester) that is produced from isoamines and alcohols. Polyurethane coatings and adhesives in many cases are obtained from isocyanates, which are mixed with another component - various compounds with an active hydrogen atom, epoxy resins or their derivatives with amines. It uses the quality of the mixture to expand repeatedly with a controllable delay.
It is used in the form of soft to very hard foam as thermal insulation and adhesives in construction, for the production of machine parts, as a coating (makes fighter planes practically invisible to radar), etc. Sealing is the main purpose of polyurethane foam. Its sealing effect is particularly useful for filling holes and voids in concrete, plasterboard and masonry. Thermal insulation - the properties of polyurethane foam are due to its low thermal conductivity (from 0.019 W / m K. to 0.023 W / m K.). For example, a layer of polyurethane foam 2.5 cm thick has thermal conductivity identical to a wooden beam 19 cm thick or a brick wall half a meter thick. Soundproofing- As mentioned above, after hardening, the mounting foam is a porous material. Pores are cells isolated from each other and filled with air. Such a structure is a stable and effective barrier to a sound wave. Mounting properties of the foam are used to fasten and fix structures made of metal, wood and PVC. For example, when installing windows or for additional fixing of water pipes.
- High degree of resistance to mechanical stress.
- Simplicity and ease of use, good foaming.
- Adhesion to various surfaces, low thermal conductivity.
- Prominent waterproofing and soundproofing properties.
- Preserving the integrity of the seam by compensating for deformations.
- Resistance to paints and varnishes, ease of cleaning.
Cleaner and degreaser - chemical products with very high cleaning power. Penetrates aggressively and quickly dissolves even hardened lubricants and dirt. Dries quickly and without residue. Does not cause corrosion and does not damage plastic or rubber parts and seals.
- Very high cleaning power
- Does not damage plastic or rubber parts
- Quickly dissolves even hardened lubricants
- Easily cleans hard-to-reach places
- Does not cause corrosion Improves the performance of the braking system
*For painting, use acrylate or polymer products.
*For use on synthetic materials, use neutral silicones.
*For use with natural stone, use specialized adhesives.
*Surfaces must be clean, dry and degreased. Apply the sealants evenly.
