The paints and coatings category, which accounted for the biggest share of the coupling agents market in 2021, is anticipated to expand at a CAGR of 4.8% from 2022 to 2027. Coupling agents are non-flammable paints and varnishes with a high lifetime and durability. To improve adhesion, these ingredients are added to paints and coatings.
Sulfur silane, vinyl silane, amino silane, and other coupling agents improve surface strength, corrosion resistance, UV and thermal stability, chemical resistance, and scratch resistance. The market for paints and coatings is predicted to develop as a result of the house-building industry's expansion and the quickly growing technological advances in paint technology.
Market Segmentation Analysis for Coupling Agents by End-use Industry
Building and construction held the highest market share for coupling agents in 2021, and it is anticipated to expand at a CAGR of 5.1% from 2022 to 2027. Coupling agents are used in the building and construction industry in adhesives & sealants, paints & coatings, and other applications to significantly reduce porosity in renders, concrete, and plasters and make them water-repellent. They also increase the bonding between the polymer matrix and the fiber surface. It functions as a form of mechanical seal by connecting and sealing the passage
Coupling Agents Market Drivers
1. Growing Automotive Industry
Coupling agents are used in the automobile sector to improve the bonding between the polymer matrix and fiber surface as well as to seal microscopic fractures in engine cooling systems, radiators, and head gaskets. Over time, the head gaskets frequently grow brittle and might leak. These leaks are sealed by coupling agents, extending the gaskets' useful life. These substances enhance the wet traction, rolling resistance, and manufacturing effectiveness of vehicle tires.
2. Growing Electrical and Electronics Sector
Because of their high temperature, UV and humidity resistance, high cohesiveness, peel strength, and high transmittance properties, coupling agents such as sulfur silane, vinyl silane, amino silane, and others are used in the electrical and electronics industry. Tablets, monitors, mobile phones, televisions, outdoor signage, and other electrical and electronic gadgets are all made with coupling agents.
