YL-SG SODIUM GLUCONATE
YL-SG SODIUM GLUCONATE
Description
YL-SG is a kind of sodium polyhydroxy carboxylate in white or light yellow crystal powder. It is easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It is widely used in many industries, like concrete, textile printing, metal and water treatment, etc.
Performance
●Used as a concrete additive: it can slow down the hydration of cement, prolong the setting time and extend the service life of concrete, no negative effect on the quality of concrete in hot weather;
●Used as steel surface cleaning agent. If the steel surface needs to be plated, chromed, tinned, or nickel-plated for special purposes, the addition of sodium gluconate to the cleaning agent can achieve very good results;
●Used as a special cleaning agent for glass bottles. It has strong detergency and ideal performance for removing bottle stickers and bottle neck rust，especially for solution of incrustation block problem from bottle washer in nozzles and pipes;
●Can be used in many industrial fields such as electroplating, film manufacturing, etc;

Dosage
As concrete retarder, recommend dosage with 0.01% to 0.1% by weight of cementitious material, actual dosage depends on the test. It is also available to consult our technicians.
Note
When use as Concrete Retarder, please pay attention as follow:
1.Dosage is based on the percentage of cementitious material weight.
2.If mixing with other functional admixtures in solution under hot weather, it is better to mix for immediate use to avoid the solution get bad and mouldy.
3.If using this product for the first time, or cement and other admixture changes, test is required to redetermine the best dosage.
4.Dosage is better no more than 0.2%, excessive dosage may affect the bleeding rate and strength of concrete.
