Adherence to rigorous standards of environmental and safety protection remains one of the main barriers for participants in the electronics sealants market due to several reasons, including the existence of various safety and chemical standards applicable to their products. It means that companies would have to get rid of or reduce the toxicity of substances that they use, such as solvents and heavy metals that they incorporate into their products. As a consequence, they will incur additional costs associated with the process of formula adjustment and the lengthy approval process because of conducting additional tests, which makes the entrance of smaller firms difficult. In addition, there are certain international standards (RoHS and REACH) that require companies' efforts and extensive documentation.

The use of high-quality raw materials and the potentially labour-intensive manufacturing process are some of the main reasons contributing to the high cost of electronic sealants. These products generally require special raw materials such as high-purity silicones, epoxy resins, and advanced chemicals, which are not only pricey but also have limited suppliers. The production line needs to be in a sterile environment, equipped with accurate machines, and have strict quality control, which obviously leads to an increase in the manufacturing costs. Moreover, rising energy prices and transportation costs put more pressure. With electronics products getting smaller and more functional, sealants have to be of even higher quality, so producing them becomes even more expensive.

In November 2025, Henkel introduced two state-of-the-art thermal potting silicone compounds, Loctite SI 5643 and Loctite SI 5637, aimed at increasing thermal management of electric vehicle power electronics. These quick-drying, low-viscosity two-component systems would be capable of enhancing heat dissipation and increasing the reliability of power inverters, electric drivetrains, and battery management systems. Since the power electronics of EVs generate a lot of heat, these compounds provide a higher thermal conductivity for efficient heat management while also offering electrical insulation to safeguard sensitive high-voltage components. Moreover, their quick-drying property also makes the production processes faster - therefore, manufacturers will get a better throughput. This innovation is a testament to Henkel's dedication to the EV industry through providing materials that not only improve the performance of power electronics but also their longevity.

In July 2025, WACKER made its debut at the China International Supply Chain Expo (CISCE).
