Application


  • ADDSiL™ 11820 silicone surfactant for PU rigid foam provides extremely fine cells and therefore low thermal conductivity with pentane.


  • ADDSiL™ 11820 brings very good fluidity during the entire foaming process in the reaction system, so polyurethane foam can obtain superior silicone adhesive strength. It is especially suitable for refrigerator systems or systems for pipe insulation.


Packing and Storage


  • ADDSiL™ 11820 surfactant will become hazy when stored at temperatures below 20°C and will solidify to a soft silicone wax at temperatures below 10°C. The product should be warmed to room temperature and stirred before use.


  • ADDSiL™ 11820 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.


  • When stored at ambient temperature in the original unopened packing, ADDSiL™ 11820 has a shelf life of 12 months from the date of production.
