Elastic adhesiveSuper X series
Elastic adhesive | Super X
Cemedine Super X is an innovative one-part, quick cure adhesive with three key features: "Pressure-sensitive adhesion", "Elastic adhesion" and "Solvent-free adhesion", which are the ideal properties of adhesives. It is used around the world.
Super X products allow for adhesion of various types of plastics, rubbers and ceramics over an extensive range, and also over different types of metals. These products provide excellent adhesion over a very extensive range of materials, eliminating the need for selecting a particular adhesive for each type of material, as in the case of conventional adhesives.
Curing reaction is caused by moisture absorbed from the air. Pressure-sensitive range is reached in this curing process about 10 min after application. If adherends are put together during this time, they bind instantaneously as in the case of rubber contact adhesive, eliminating the need for temporary fixation. Easy-to-use, safe, and clean adhesive featuring one-part solventless capable of quick curing at room temperature is provided.
Super X as elastic adhesives does not peel off. Once materials are adhered, Super X provides durability in the range from low temperature (-60°C) to high temperature (120°C). Because of the rubber state of the hard film, the Super X sufficiently follows expansion, shrinkage and other changes of adherends.
There is not including low molecular weight cyclosiloxane. (D3 to D10 Cyclosiloxane compound)
