It is a well know fact that the Foundry Coatings are widely used to improve the surface casting finish and to achieve the best cosmetic look of the castings. But at the same time we all know that the best of the Foundry coating can never achieve this on a bad core or moulds. A conventional foundry using Sodium silicate CO2 gassed binder system uses mostly solvent based refractory coatings. In view of improving productivity, castings quality, to reduce rejection %, to have cleaner environment in the foundry, all modern foundries are shifting to modern resin systems such as phenolic ester cured, cold box resins, shell sand (Hot-Box), Furan Resin, Alpha set etc. Most of these sand resin systems whether for moulds or cores utilizes water based coatings to avoid casting defects such as metal penetration, sand erosion, veining etc.

He Started Hindustan Metal Chemicals, another Flag-Ship company of the group in 1971 to replace costly Atomized Aluminium powder used in manufacturing of foundry chemicals & Fluxes. In 1987, He started Shamlax Polychem, Jointly with his son Mr. Sushil Sharma, a Chemical Engineer, as a step towards catering to the needs of Foundries in Central India.

Zircon Solvent based yellow colored coating, suitable for Sodium-Silicate Alpha Set Resin Sand System. Changes color from Yellow to Orange on ignition. To eliminate all moisture related defects To identify poor sand compaction in a core or mould. [as these areas will absorb more moisture from coating and will take longer time to dry] To optimize on cost of drying – Avoid over heating by oven torch

Sandaid-50 – is a lustrous carbon additive specially designed with selected volatile content for iron foundry green sand. Exoaid–61 - is a sand additive to eliminate sand expansion defects such as scabs, buckles. Exoaid-61 high burn-out temperature contents and results in lower concentration of dead clay. This improves permeability, reduces moisture requirements and gives better all-round sand properties over a longer life-cycle. Addition % of Exoaid – 61 is 0.5 - 1.0 % in the facing sand. If it is added in total sand system than 0.05 – 0.1% is sufficient. Exoaid–81 – is an anti veining sand additive. It is free from contaminants such as oil, moisture, acid salts, slag and gangue minerals.

Exo-14 Exo-16 Hi-APC-10 In case of pouring liquid metal in the mould, casting cools at a slower rate than the riser metal. While cooling, casting metal shrinks & the metal is feeded from the riser. But the riser metal is cooling at a faster rate. Hence to keep riser metal in the liquid form for feeding the casting, EXO-16 is used. The moment riser is filled with the metal, EXO-16 is spread over the riser surface. EXO-16 starts burning after few seconds. The activity count of 65 is adjusted so as to generate heat & keep riser metal hot at a latter stage. EXO-16 swells and provides a insulating layer to retain the heat generated & helps in feeding the casting. EXO-16 is recommended for all riser sizes above 3" and heavy castings.
