A polyurethane (PU or PUR) sealant is used for bonding and sealing metal, plastics, GRP, aluminum, glass, wood, stone and concrete. It always remains elastic and is paintable with most paints. The PU sealant is a convenient 1K product that comes in a tube and reacts to humidity. It is universally applicable both in the transportation and construction industries. PU joint sealants are available for various applications both indoors and outdoors.
Polyurethane adhesive and sealant with a high e-modulus
Thanks to their high wear resistance and chemical resistance, PU sealants are ideal for sealing in industry. Available in a few colors, they have a Shore A hardness of 40 and an elongation to failure of 700%.
Polyurethane Marine Sealant
These kits are made for bonding and sealing, in particular, applications to a boat. Think of the grouting of a teak deck or the elastic joining of the keel to the hull. Due to the unique composition of these joint kits, the polyurethane remains elastic after curing and is resistant to seawater and the sun. Ideal for cosmetic applications. You can also use these as a waterproof adhesive. The elasticity of this joint sealant provides an ideal joint that is insensitive to vibration, shock, expansion and shrinkage. And can be used both above and below the waterline. Polyurethane Marine joint sealants are available in white and black.
This is a joint and adhesive sealant consisting of the latest generation of MS polymers. Universal Hybrid contains no isocyanates and is completely crystal clear. Ideal for transparent bonding or sealing. Universal Hybrid is fast drying and cannot be painted over. The joint sealant has excellent adhesion to almost any substrate. This hybrid joint sealant is permanently elastic and extremely suitable for all filling of joints and seams, in order to seal them watertight in and around the house. This can be done on both porous and non-porous substrates and both indoors and outdoors. Ideal sealant for construction on boats or in industry. Sealing of floor joints in sanitary applications.
