Function & Characteristics

UB-6842 is a reactive hot-melt adhesive based on polyurethanepre-polymers. The adhesive is pressure sensitive and provides a high initialstrength instantly after joining the parts.

Additionally it has a long open time to be suitable forautomatic or manual assembly line.

UB-6201 is a two component polyurethanecompound that was formulated for potting electronic control modules (ECM's).This product can easily penetrate into the gap of the module with excellent flowingability, and exhibits excellent insulation. The productadheres well to metals and plastics

Product Application

UB-6842 can be applied from heating cartridge guns, fromusual syringe type melting equipment. At longer rest periods, melting andapplication temperatures should be decreased. Longer exposure to highertemperatures can lead to a viscosity increase

UB-6201 can be used for electronic controlling modelsprotective potting in fields of electromechanical etc. It can act asinsulation, anti-shock, and water proof
