The Silane coupling agents are used in paints and coatings to enhance adhesion. Silanes help enhance UV and thermal stability, surface strength, chemical resistance, and ability to protect against corrosion. They are majorly used for adhesion promotion as well as enhancing corrosion resistance and scratch resistance. Siloxane-alkyd, siloxane-epoxy, and siloxane-acrylic chemistries are used to achieve low viscosity, low VOC, high solids, metal adhesion, cement and quartz-like surfaces, low combustibility, high heat and UV tolerance in automotive, architectural, and marine antifouling coatings. Silanes are also used as the feedstock for a thin-coating industrial sol-gel process. Paints & coatings find a wide range of applications in major end-use industries such as automotive, construction, and aerospace. In the building and construction industry, paints and coatings are used to enhance the esthetic appeal of the structure. The growth of the building and construction industry, with the rising residential and non-residential construction, across the globe has fueled the demand for paints and coatings.
For instance, according to the US Census Bureau, the overall construction spending in the US stood at USD 1,524.2 billion as of April 2021, a 9.8% increase compared to April 2020. Furthermore, the increasing construction and infrastructure activities in developed and developing economies in Asia Pacific, such as India, China, Thailand, and Malaysia, due to rapid urbanization and industrialization is projected to propel the demand for silane coupling agents.
The global Silane coupling agents market is estimated to be USD 1,221.2 million in 2021 and is projected to reach USD 1,593.8 million by 2026, at a CAGR of 5.5%. The growth is due to the growing demand from rubber & plastics, paints & coatings and other applications throughout the world. The rising demand from the automotive and building & construction sectors in developing countries such as China and India are driving the market. North America and Europe have introduced stringent regulations for tire labeling and fuel efficiency which act as drivers for the silane coupling agents in production of green tires. Also, the new trend of low VOC paints & coatings is now changing the focus of industry toward powder coatings.
Silane coupling agents is a diversified and competitive market with a large number of global players and few regional and local players. Dow (US), Wacker Chemie AG (Germany), Evonik Industries (Germany), Momentive (US), Shin-Etsu Chemical Co. Ltd. (Japan), are some of the key players in the market.
