Con-Lub SP (Water Reducer/Plasticizer)

A High Range Water Reducer/Plasticizer, Type- F/G, ASTM-C494

Con-Lub SP is white in colour; liquid is paste like mass, depending on temperature. It is soluble in water. It is used in Reinforced Cement-Concrete, Cement-Concrete and plastering, etc. in a word, for all kind of concrete. Con-Lub SP is linear polymerize between cross-linked small lumps in the concrete masses. It also reduces water-cement ratio remarkably, procuring satisfactorily high work-abilities and strength of concrete.

Con – Lub SP mainly composed of  2, 3, 4- Hydroxyl Stearatopolycarboxalate ether, diaminolauayl oxalate, diamino citrate, excluding leadazole, aluminous derivatives of leadazole 2,3-dinitro methylethyl-4,5, dicarboxylic acid [patent No.20/94 (serial no. 1002563) int.Gl⁵ E02D 31/02], hydrolized  TRO(sulphonated), Trihydric alcohol, organic-inorganic citrate(diaminolauayl citrate)/ poly phosphate or competitive others act as one of the retardants,  competitive graft able  emulsified monomers of salts & Ester of Fatty acids & oils, etc. ; for very special properties , different ingredients remain in grafted form with the main polymer chain, catalysts and auto-catalysts.

It’s very slippery, water soluble & dispersed when used in Cementitious concrete & cement mortar passing the cementitious reaction process.

Composition of Con-Lub SP:

Name Quantity (%)
2, 3, 4- Hydroxyl Stearatopolycarboxalate ether 44%-47%
Diaminolauayl oxalate 0.6%
Diamino citrate 3-4%
Excluding leadazole 0.005%
TRO 0.25%
PolyTrihydric alcohol 0.25%
