|Description||KEMAFLEX PU is 1-component, polyurethane-based sealing-adhesive compound, for sealing dilatation joints in construction and bonding construction and metal materials.
|Field of use||Perfectly adheres to most materials used in building engineering as well as in industry. It is used for:
– Dilatation joints in construction
– Sealing and bonding metal and construction materials
– For adhering window frames, light construction materials, roof decking, floor panels. For sealing joints in vacuum systems, networks of compressed air, containers, tanks, silos, aluminium constructions, sewerage systems.
Good adhesion on most construction and metal materials
Good mechanical properties
Does not slip in vertical joints
Can be painted over
Very good resistance on different weather conditions
Good UV resistance
Correct dimensionimg of expansion joints
To reach optimal elastic properties of sealing compound it is important to have the right ratio of width to depth. (that is 2:1, or max. 1:1) Seealing compound shoud not have adhesion on botttom of the joint, but just on the sides of the joint. We can achieve this with using inert underlying materials (like KEMAFLEX PE X10). Minimal width of joint should be 6 mm and maximal 20 mm.
