  Bladder coating agent SBC-7086 is the product of the technology cooperation between China and Germany.It is a semi-permanent tire bladder release agent.It is free from solvents and silicone oil. The active ingredient is a reactive silicone polymer.The product provides a long store time and a steady property.It has no terrible smell. Low consumption and a short drying time make the product very economical.The product provides an excellent slippage of the bladder into the green tire and a very good release effect after the cure. Its use will extend bladder life and prevent air traps and tire shrinkage.So scrap parts will be reduced.

Application fields

  Semi-permanent bladder coating agent for passenger car tire, truck tire and rubber production.


  As a first step the bladder has to be cleaned using alcohol to be sure there are no residues left that might impair the coating. Bladder coating agent SBC-7086 is then applied by wiping it directly on the new bladder in an undiluted form.Afterwards you should give enough time for the coating to dry and to bond on the surface of the bladder (about one day). At the time of cure bladder coating agent SBC-7086 needs to be diluted with water in the ratio 1:2 to1:5.It is sprayed on the surface of the bladder using atomizing or airless spray systems. The product has virtually no tendency towards sedimentation. However, we recommend to stir it gently during processing. The product needs to be wiped per 1-2 times cure before 10 times cure , from then on it is wiped one time for one day or one class.
