خواص و ویژگی ها
After the two components have been mixed, UHU plus hardens with almost no loss of volume to form a
duroplastic synthetic resin. The parts to be assembled usually need to be fixed under pressure. It is not necessary to apply
extreme pressure. Hardening takes place by evaporation. The working cons istency is so designed that a good bond is
achieved at room temperature with a minimal amount of movement. The UHU plus system enables the user to achieve a
harder or softer final product by varying the quantity of hardener used
نحوه استفاده
UHU plus joins are resistant to moisture, oil, dilute acids and alkalis and many solvents.
Moisture, dilute acids and alkalis have very little effect on bond strength, even in the event of lengthy
exposure. No universally valid data can be given as there are always many factors, such as the possibility of
corrosion, duration of exposure and temperature, that affect the assembly. Some solvents, such as
methylene chloride and trichloroethylene (Warning! Precautions must always be taken when using these
substances!), soften the adhesive over a period of time. This effect can be made use of for dissolving
adhesive joins. UHU plus is resistant to ageing and weathering. The adhesive is not affected by even
extremely low temperatures. At temperatures below –60°C, resistance to combined tension and shearing is
reduced to approximately 75-80% of the value measured at room temperature; if the samples are heated
up to room temperature once more, the original bond strength is also regained
