Sealant home decoration how to avoid pit

With the development of economy and the progress of science and technology, people's demand for doors and Windows is increasingly high, from the initial simple wind, rain and lighting, to the present thermal insulation environmental protection noise reduction, great changes and upgrades have taken place. Therefore, the development of doors and Windows is changing with each passing day, from ordinary wood doors and Windows, steel doors and Windows, to the present plastic steel doors and Windows, aluminum alloy doors and Windows, wood and aluminum doors and Windows, and even the most popular system doors and Windows. And the matching hardware, rubber strip, sealant and other accessories have therefore been very rapid development, and continue to introduce new categories, quality. Today, we will focus on understanding these various home sealant. I hope to guide you to have a deeper understanding of sealant in the process of home decoration and avoid some unnecessary trouble.

A, neutral silicone sealant

Neutral silicone adhesive is now the most commonly used door and window installation sealant on the market. It has good bonding strength and sealing performance for the vast majority of materials, excellent electrical insulation performance, good high and low temperature resistance, outdoor aging resistance, long service life.

Two, MS modified silane polyether adhesive

MS (silane modified polyether), because it does not contain formaldehyde, does not contain isocyanate, has solvent-free, non-toxic, tasteless, low VOC release and other outstanding environmental characteristics, friendly to the environment and human body; Adapted to the vast majority of building materials, with good construction, bonding, durability and weather resistance, especially with non-pollution and coating property, has a wide range of applications in architectural decoration. Suitable for adhesion of various kitchen hardware, ceramic tile, mirror, decorative painting, wood, concrete, stone and so on.

Three, polyurethane PU sealant

One component moisture-cured polyurethane (PU) sealant is widely used in civil construction, transportation and other fields, it has high strength, good elasticity, tear resistance, wear resistance, puncture resistance, no pollution to the substrate, acid and alkali resistance and organic solvent resistance, paint and other advantages, but because one component PU sealant is sensitive to moisture, It is easy to lead to unstable storage and weak long-term ultraviolet aging resistance; And the curing process releases CO2, easy to form adhesion damage, resulting in metal, glass and other smooth surface substrate bonding is not strong, so must use the bottom coating to improve its adhesion and UV aging resistance.

Four, SPU silanized polyurethane sealant

In addition to retaining the advantages of the original PU sealant, this kind of sealant has been greatly improved in heat resistance, aging resistance and weather resistance. It has good bonding effect on metal, glass, PVC and other commonly used substrates, and it does not contain free isocyanate, no pollution of curing exudate escape, will not pollute the surface and surrounding of the adhesive substrate, more in line with the requirements of environmental protection.

Five, STPU modified silane resin sealant

STPU sealant is a single component, high performance, neutral polymer resin curing adhesive. The product green environmental protection, does not contain toxic and harmful substances, metal, ceramic, wood, polyvinyl chloride (PVC), polycarbonate (PC) and other most substrates have good bonding ability, curing surface can be coated.

Relative to polyurethane: no toxic NCO; Excellent weather resistance; Curing without bubbles; Good adhesion with a variety of organic/inorganic substrates; No base coating is required for bonding. Relative to silicone: paintable; No silicone contamination; Silicone-free volatile matter; Good adhesion with a variety of organic/inorganic substrates; Better mechanical properties

Six, hybrid STP-E sealant

"Hybrid" STP-E sealant, also known as organosilicone modified polyether sealant, modified silicone sealant, is a silicone alkyl polyether based polymer of high performance elastic sealant. The hybrid STP-E sealant inherits the advantages and advantages of silicone and polyurethane sealant. At the same time, it shows excellent weather resistance and durability, high deformation and displacement resistance, good adhesion, finishing, environmental friendliness, construction and low viscosity and pollution.

Do you feel dazzled after watching it? It doesn't matter, I believe that we have a preliminary understanding of the types of sealant, so in the process of home decoration, the choice of sealant will be less or no longer step on the pit! With the development of future science and technology, I believe there will be more suitable for the birth of Chinese home sealant, but also hope that in the future of the home decoration process, we must understand the advantages and disadvantages of various types of sealant, because of the material "glue", in order to better control the impact of the sealing tape in the process of home decoration and reduce trouble!
