EGO POLYURETHANE (PUR or PU)

 

EGOFLEX is a PU or polyurethane sealant and adhesive that is used for elastic sealing in building and civil engineering, as well as for structural bonding in industry.

    EGOFLEX - FOR A ROBUST JOINT

    Overview EGOFLEX

    Possibilities of density, handling temperature, temperature resistance, Shore A hardness, module/tensile stress, acc. total deformation, viscosity, skin formation time, functional strength, hardening time/complete vulcanisation, resilience and standard colours.

    Overview EGOFLEX

    Possibilities of protct types, spec. Application cases and tests.

    EGOFLEX 401, EGOFLEX 421 and EGOFLEX 423 products are resilent and elastic PUR sealants which cure by reacting with humidity in the air. They are perfect for sealing expansion and connection joints. Our PU sealants are characterised by bubble-free curing and easy smoothing and processing properties. They are designed for use in areas with concrete, plaster, brickwork, timber and metal, among others.

    Perfect for:

    • Building construction, warehouses, underground car parks, staircases and tunnel construction and much more.

    EGOFLEX 471 is a robust two-component PU adhesive with a very short processing time. It is ideally suited for structural bonding with very fast functional stability. It is designed, among other things, for use in areas with concrete, natural stone, fiber cement, wood, ceramic, polyester.

    Perfect for:

    • Facade, vehicle, kitchen, shop construction and much more.

     

     

    Frequently asked questions

    What areas are polyurethanes (PUR) used in?

    Depending on the product quality, EGOFLEX products can be used in a wide variety of areas of application.

    For sealing of expansion and connection joints in building construction, both indoor and outdoor, for concrete, plaster, masonry, timber, metal and hard PVC, among others.

    For floor and connection joints, both in indoor and outdoor areas, such as storage halls, underground car parks, production halls, yard areas, multi-storey car parks, entrance halls, staircases, both in concrete and floor screed. Joints for waste water and sewage treatment plants as well as tunnel construction and in clean rooms.

    For construction bonding of natural stone and polymer concrete profiles on worktops in kitchen and shop construction, as well as for applications in facade and automotive construction. For construction of aluminium windows, doors and construction elements, for bonding of blind frame profiles, corner brackets and corner connections.

    What do I need to consider when using polyurethanes?

    Not suitable for glass. In general, the contact surfaces should be dry, stable and free from dust and de-bonding agents. See the EGO technical data sheets. Not suitable on glass.

    Can polyurethanes be painted over?

    Fully painted sealant joints tend to crack with joint movements since the paint applied accommodates less expansion than the sealant beneath it. DIN 18540 says “joint sealants should not be painted over.”
