Focusing on 3 superior sealants offered by Den Braven, which provides sound adhesion while still remaining flexible.
Den Braven silicone sealants are used as adhesives, sealants, coatings, heat insulators, and encapsulating material. They are widely used in the construction, sanitary, DIY and industrial sectors where high quality seals, adhesion with high joint movement tolerances are required. After application the silicone cures with atmospheric moisture to form a durable rubber seal.
Falling in the class of being both a sealant and adhesive, it is important that the Den Braven silicone sealants provide sound adhesion whilst still remaining flexible. Surface preparation is very important in order to obtain a good adhesion. Surfaces must be clean, dry and sound. Den Braven sealants retain their adhesion and flexibility even after many years, and adhere well to many substrates. The sealants’ mechanical and physical properties remain virtually unchanged to ageing or exposure to weather.
Den Braven’s solvent-free, emulsion-based Woodflex range is ideal for use on parquet, cork, laminate, wooden and bamboo flooring and skirtings. It is used to fill and seal gaps, cracks and joints where some movement capability (up to 8%) is required. Woodflex is also fast-drying and easy to sand and paint once fully cured. It is available in a selection of six popular wood colours to aesthetically match and finish the desired look and feel.
They are packaged in unique, exciting, transparent cartridges, making colour matching and identification both simple and efficient. It can be applied quickly and with ease by making use of a caulking applicator, and tooling off the sealant is simple.
Considered a convenient expansion joint sealer, Den Braven’s Hybriflex 540 product is designed for effective versatility and to reduce the number of products needed in building and industrial projects. It offers excellent adhesion to a wide range of substrates, efficient movement capability and only requires minimum surface preparation.
Hybriflex 540 can be used to seal all types of external or internal façade joints, expansion and construction joints, as well as joints in precast elements. It is chemical- and tear-resistant – an important criterion when one considers the chemicals and detergents used to keep floors sanitised. Furthermore, the product does not bubble or yellow and has high resistance to UV degradation and weathering, making it ideal for use with backing cord, which is also available from Den Braven.
Another product offering from the company, High Tack, claims to be ideal for civil, industrial engineering and DIY use due to the fact that it is a high-grip, strong MS Polymer adhesive. MS Polymer is a new generation of solvent- and isocyanate-free sealants. As such, High Tack is a heavyweight adhesive with high initial adhesion power. It is also UV- and water-resistant, odourless, low in VOCs and free of silicone and isocyanides. It also conforms to SA Green Building Council standards.
In addition, Den Braven High Tack adheres to many substrates such as natural stone, windowsills, mirrors, glass and glazed surfaces, coated metals, steel and finished wood. As it is non-corrosive, it is compatible with most metals.
These are just three of a range of unique, highly innovative products – each infused with technologically advanced materials to ensure an end product built on a foundation of superior performance.
