  • ADDSiL™ 11210 silicone based surfactant has good solubility in all common types of polyether polyols used in polyurethane rigid foam productions.

  • ADDSiL™ 11210 is recommended for use in rigid lamination, pour-in-place, insulation panel and appliance applications.

  • ADDSiL™ 11210 provides good compatibility in the premixed systems containing polyether polyol, water, amine and fire retardant, avoiding haziness and phase separation.

  • ADDSiL™ 11210 silicone surfactant for PU rigid foam by SiSiB 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™ 11210 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™ 11210 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.

  • When stored at ambient temperature in the original unopened packing, ADDSiL™ 11210 has a shelf life of 12 months from the date of production.
