Application


  • Ureido-functional silane has better stability than amino silanes in reactive silicone polymer systems, like phenolic, epoxy, urea-melamine or polyurethane.


  • Ureido-functional silane does not generate color with time and aging.


  • Ureido-functional silane has good adhesive and sealant adhesion to oil metals.


  • Ureido-functional silane provides nitrogen reactivity without typical amino silanes strong basic characteristics.


  • VANABIO® US5251 can be used for glass fiber sizes and finishes, wool insulation resin binders, numerous primers, foundry sand binders, adhesives, sealants and abrasive grinding wheel binders.


  • VANABIO® US5251 can improve adhesion between the inorganic silicone filler or fiber and the polymer.

Packing and Storage


  • VANABIO® US5251 is supplied in 220Kg steel drum.


  • In the unopened original container VANABIO® US5251 has a shelf life of one year in a dry and cool place.
