Sulphonate Melamine Formaldehyde Resin Superplasticizer SM
1. Description
Chemistry:
WNT - SM superplasticizer is a free-flowing,spray dried powder of a sulphonated polycondensation product based on melamine. It has very strong absorption and dispersion effects to the cements.It is the one of leader concrete superplasticizer which have the better integrative index.
Characteristic:
WNT SM superplasticizer main characteristics include: with white colour, high water reducing effect,non-air-entarained type, low Cl ion content to avoid steel-bars corrosion, and good adjustability to different cement. The early strength and impermeability are obviously increased after use this product. And 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.
2. Fields of Application
High strength motar, Gypsum products, Self-leveling floor,Filler,Grouts etc;
High strength concrete ,High fluidity concrete,High endurance concrete, Aluminate cement refractory concrete, Low cement refractory castable, steam curing concrete;
It can be used as brightened agent for colorful cement blocks and concrete precast.
