Physical And Chemical Propertices

Particle size	98.5% passes through 100 mesh; 100% passes through 80 mesh.
Charring temperature	280-300°C.
Bulk density	0.25-0.70 g/cm3 (Usually around 0.5 g/cm³)
Real specific gravity	1.26-1.31.
Browning temperature	190-200°C.
Surface tension	(2% water solution) 42- 56dyn.cm.
Properties	Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent.Gelation temperature is different for different grades. For example, among 60RT Hy-droxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.

Lubrication

Improves workability and processing effect of cement-based and ceramic-based extrusions by its lubrication

PH stability

Double-bulls@remains stable in the range of pH 3.0~11.0. The solubility of Double-bulls⑧can largely increase in the presence of alkali environment.

Open time

Double-bulls⑧prolongs the open time during application, give more time for correction.

Water retention

Avoid quick water-loss during the drying of constructions, enhance water retention, ensure sufficient hydration time for cement-based, lime-based and gypsum-based materials.

Stable Chemistry

Compatible with other ionic and non-ionic additives in aqueous solutions while providing a stable combi-nation when dissolved in water.

Save Cost

Large water demand of Double- bulls⑧can make your materials yield higher volume of outputs, and thus save your cost.

Suspension Effects

Enhances dispersion rate suspension effect and the stability of suspension systems, including concrete, mortar, EIFS system.

Thickening Effects

Double-bulls⑧Increases viscosity of liquids in daily-chemical products and personal care products
