What is a hybrid sealant? In lay terms, it is the result of combining high performance polyurethane and silicone chemistry which produces a sealant with the best properties of two or more families of polymeric materials, but limiting their individual inherent weaknesses. It has the strength of polyurethanes and the weather resistance of silicones and is sometimes referred to as an MS (modified silicone) Polymer.
Den Braven Hybriflex-540 is a hybrid sealant which has been on the market for over 10 years and has proved to be extremely dependable, especially in the South African climate. There is a growing trend for higher performance sealants due to the need for sustainability, and to comply with building and environmental regulations and requirements.
Hybrid sealants are specifically developed to use as universal sealants, primarily for sealing construction and dilatation joints. These could be joints in pedestrian walkways, perimeter sealing of windows and doors and are used on most common building materials such as concrete, brickwork, painted wood, enamel, aluminium, stainless steel and a variety of plastics.
Because of Hybriflex-540’s hybrid technology it is also ideal for:
- sealing of floors – tiles and laminated;
- natural stone applications such as cladding and countertops; and
- sanitary applications such as sealing showers, baths and vanities.
It has become a firm favourite with one of South Africa’s biggest lifestyle estate developers and is specified for use throughout their developments, across a multitude of construction applications and finishings.
It is suitable for use both indoors and outdoors as it has a durable rubber seal, making it weatherproof and UV resistant. Hybriflex-540 also ticks the environmental box as it is isocyanide free and low in volatile organic compounds – this is a very important consideration when using a sealant in confined indoor areas. It is also a sustainable product and complies with the requirements of the Green Building Council of South Africa.
Den Braven encourages consultation with its technical experts who will discuss your requirements, appraise areas of application and, if necessary, give training to construction site employees on how to apply a sealant. Correct application is a very important aspect for the outcome of the job.
Den Braven Hybriflex-540 comes in either a 300ml cartridge or 600ml foil pack, is available in black, white and grey and is paintable.
