The Challenge

The rapid economic development has driven the rapid changes in the construction industry. The traditional building structure is now being replaced by frame structure, aluminum alloy doors and windows, lightweight wall prefabricated parts and various curtain walls. Such variety of architecture forms place higher demands on sealing and bonding. On the other hand, with the further improvement of people's living standards and deeper understanding of energy conservation and environmental protection, the demands for safety, health, comfort, and low-carbon environmentalism have kept growing. The choice for environment and products is becoming more and more critical.

In the construction industry applications, silicone sealants provide reliable weather proof and thermal insulation guarantees for buildings, ensuring the energy efficiency and lifetime of buildings. Practitioners in the construction industry need superior-performance sealants to meet the needs of consumers and property owners. These sealants must be able to form flexible joints, make building materials well bonded, and protect homes, offices, and industrial facilities from a variety of extreme climate changes and impact from temperature changes, humidity, wind, and other environmental factors.

Why us

As the inventor and successor to the world's first silicone sealant, Elkem Silicones has been conducting in-depth research in the field of building seal protection and energy-saving building construction since the 1950s. The world-renowned French Louvre Pyramid built in 1988 adopted Elkem Silicone sealants. The Pyramid has survived 30 years of suns and rains and still maintains its beauty and magnificence, witnessing the climate changes year after year, alongside the 800-years old of Louvre Museum.

The expert team of Elkem Silicones takes environmental protection requirements into consideration at the early stage of product development, controls or restricts the use of solvents and other volatiles, and evaluates the factors of energy-saving, environmental protection and impact to humans according to the material requirements of green buildings, to implement the green development idea with prominent products. At the same time, it also fully explores the properties of silicone, takes the advantages of silicone in weather resistance, heat and cold resistance, and aging resistance as application in sealing materials for building protection. The in-market products can effectively improve the overall sealing, energy-saving performance and life time of buildings, without compromising green environmental and utility performance, thus help customers to meet the most critical market needs.
