Application


  • ADDSiL™ 11220 silicone surfactant for PU rigid foam provides very good fluidity during the entire foaming process in the reaction system and produce homogeneous density distribution.


  • ADDSiL™ 11220 silicone based surfactant provides excellent nucleation ability. Very fine cells and flow can deliver foams with constantly low thermal conductivities in all areas of the foamed refrigerator cabinet.


  • The recommended concentration of this product is 2% to 3% of polyol (php).


Packing and Storage


  • ADDSiL™ 11220 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™ 11220 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.


  • When stored at ambient temperature in the original unopened packing, ADDSiL™ 11220 has a shelf life of 12 months from the date of production.
