Technology Insights

It is anticipated that the room-temperature vulcanizing (RTV) type segment will increase at a substantial compound annual growth rate (CAGR) over the forecast period. In 2020, this segment accounted for around 28 percent of the market share. Room temperature vulcanizing (RTV) is used to assemble the engine, which seals all kinds of leaks in the automotive sector to allow for smooth driving even in extreme environments. This is possible due to several properties of the materials, such as their adhesiveness, water-repellency, and bonding, which make them ideal for sealing.

According to the Organisation Internationale des Constructeurs d'Automobiles, the cumulative sales of automobiles from January to June in 2020 are projected to be 2,77,79,932 and in 2021 they are projected to be 3,56,03,479. Therefore, over the projected period, the Room temperature vulcanizing type segments are driven by the increased demand for automobile sales.

In terms of revenue, thermoset or heat-cured is predicted to experience the fastest growth. Throughout the predicted period, a growth rate of 6.5% is anticipated. Cross-linked polymeric resins used in Thermoset silicone sealants are cured at high temperatures. They can be used in equipment and assembly applications in various industries, including aerospace and automotive, due to their capacity to endure high temperatures.

Radiation-cured products are expected to experience a sales increase of 6.1% over the forecast period. UV light or an electron beam is used to cure radiation-cured sealants. Utilizing UV light or electron beam technologies for curing enhances product quality while lowering production costs. Additionally, these sealants provide rapid curing at low temperatures. Over the projected period, it is anticipated that these qualities will accelerate segment expansion.

Application Insights

More than 18 percent of the market share was held by the glass sector in 2020, and it is anticipated that this segment would experience considerable growth over the course of the forecast period. The market for silicone sealants is being fuelled by the rise in demand for glass in a variety of industries, including building & construction, aerospace, automobiles, and others. Sealing gaps or cracks around windows, door frames, baseboards, decorative glass walls, molding, glazing joints, and glazing applications in kitchens and bathrooms are some of the many uses for silicone sealants in the building and construction industries. These sealants are also used to seal glass windows in buildings.

According to Glass for Europe, eighty percent of flat glass is used in building and construction, fifteen percent in transportation, and five percent for other sectors like electronic appliances and solar panels, with a total annual production of ten million tonnes in Europe. This figure accounts for the majority of the continent's production of glass. As a result, during the time period under consideration, there will be a rise in demand for silicone sealants due to the expanding use of glass.

End-Use Industry Insights

In 2020, the Construction industry accounted for more than 35 percent of the market share, and it is anticipated that this sector will experience considerable growth over the course of the forecast year. The phenomenal properties of silicone sealants, such as resistance to UV rays as well as electric, thermal, and mechanical properties, have led to their widespread application in the construction industry. These properties are contributing to the expansion of the silicone sealants market over the period covered by the forecast.

The water resistance quality that sealants provide is what is driving the industry, and these products are used to fill gaps, install fittings in kitchens and bathrooms, seal floors, make long-lasting paints and varnishes, and wire buildings and ceilings. The British Columbia Construction Association (BCCA) estimates that there is approximately 125 billion dollars worth of construction projects underway in Canada, with an additional 220 billion dollars worth of projected projects. By the year 2030, demand for silicone sealants will be driven higher by the expansion of the building industry.
