Light color CSA binder
Light
color CSA binder
General characteristics
Light
color CSA binder with grade 82.5Mpa, is a hydraulic binder based on calcium
sulfo aluminate, specially designed to be blended with anhydrite and some other
materials, such as sand, crashed stone, pigments to make artificial stone &
countertops by Polar Bear plant in year 2000.
This
binder is manufactured under a strict quality assurance systems GB/T
19001-2000(i.e. ISO9001:2000) and GB/T 240001-1996(i.e. ISO 14001:1996) which
accommodates the technical requirements of building chemistry formulators.

Advantages
by using LIGHT COLOR CSA BINDER:
1.
The color of this CSA BINDER is more lighter than other
cement, can be easily colored by pigment.
2.
Hydrated products have hydration alumina gel and
ettringite crystals which can generate beautiful luster on surface of the
artificial stone.
3.
Hydrated products of CSA BINDER are hydration alumina
gel, ettringite crystals and hydrated calcium silicate, can avoid the strength
decreasing.
4.
CSA BINDER is a low alkali cement, can avoid the
re-alkali.
5.
Hydrated products ettringite crystals, is an expansive
crystalline substance which is formed very stable over time, can avoid the
cracking and shrinkage.
6.
CSA BINDER is also a low CO2Emissions cement.
7.
Rheology Adapted to the Application
8.
Sulphate Resistance,etc.
Use
of Additives
Light
color CSA binder may be used in combination with chemical additives such as:
The
following additives might be used in combination with LIGHT COLOR CSA BINDER
when making artificial marbles and counter tops.
- Dispersible polymer powders
- Cellulose class thickening agent
- Retarder
- Accelerators
- Plasticizers/superplasticizers
- Pigments
Storage
LIGHT
COLOR CSA BINDER is normally supplied in one-tonne bag which include a moister
resistant barrier. However, in common with all hydraulic binders LIGHT COLOR
CSA BINDER must be kept from moisture, and can retain its properties for up to
six months when properly stored.
