New at Klium: Zwaluw-Den Braven silicones, acrylics, and glues

Technology for solutions

Den Braven, the Belgian manufacturer of Zwaluw sealants and adhesives, has been part of the Bostik/Arkema group since 2016, one of the largest glue and sealant producers in the world, with approximately 5,000 employees and a strong emphasis on research and product development. Let’s look at two examples of how the use of new technologies leads to practical solutions.

Acrylic sealant

Unlike silicone, acrylic sealants can be painted over. It is precisely the ideal paintability that is often the reason why people use them. But the composition of paints is constantly changing due to market developments and regulations. Different compositions immediately give paint different behaviour. Den Braven’s international R&D centres closely monitor the market and collaborate with major paint manufacturers to develop the best products. This also includes sealants that solve the two most common problems of overpainting, namely crackling of the paint skin and discolouration of the paint due to bleeding or migration. A product such as Zwaluw Acryl Anti-Crack has been specially developed to prevent cracking and migration between paint and sealant.

Silicone sealant

With the increase in new building materials, the application of sealants and adhesives in construction and industry has grown enormously in recent decades. We see a large number of new products, for example, based on hybrid technology. However, silicones still represent the largest group, thanks to properties like UV resistance, insensitivity to temperature effects and a high degree of water resistance. Because of these features, silicones have a wide field of application in construction.

Inspired by Den Braven’s example, we see the market gradually switching to more universally applicable products, such as Zwaluw Silicone-NO + Sanitary: a versatile neutral silicone sealant for sanitary, construction, glazing and facade joints, that cures under the influence of humidity into a durable elastic rubber.
