SUNBO SM
Sulphonate Melamine Formaldehyde Resin Based Superplasticizer

1. Description
 
Chemistry:  SUNBO SM superplasticizer is a free-flowing,spray dried powder of a sulphonated polycondensation product based on melamine. It has very strong absoption and dispersion effect to the cements. It is the one of the leader concrete superplasticizer which have the better intergrative index.
Characteristic: white color,high water reduction, no-air entrained type,low CI ion content to avoid steel-bars corrosion, and good adjustability to different cement. The early strength and impermeability are obviously increased after using this product. It further shows better construction properity, water retention and steam curing adeptability.This product is in line with the national standard GB8076-2008 for concrete superplasticizer index.
