ACID RESISTANT TILES

Our Acid proof tiles, Acid alkali resistant tiles, Chemical resistant tiles are fully vitrified tiles which are manufactured using special non ferrous clay, processed at extremely high temperatures this process causes the raw materials to fuse and form a compact mass with an extremely low water absorption of less than 0.5% resulting in the formation of a very strong body with a flexural strength of 38 N/mm2, solid through color fade proof with a very hard surface Mohs hardness of 7.

The acid resistant tiles come in a range of sizes and thicknesses ranging from 8-25mm. Our acid proof tiles meet stringent specification norms of IS 4457:2007 and relevant ASTM/DIN standards which ensure excellent performance in Acid/Alkali/Chemical (expect Hydrofluoric acid and its derivatives).

FURANE CEMENT

These cements are the most used in acid resistant masonry in reactor / equipment lining, and for other applications. Owing to more safer use and better shelf compared to phenolic resin cements, it is increasingly being used and specified for AR lining applications.

 

VINYL ESTER CEMENT

We are leading manufacturer & exporter of high quality Vinyl Ester Cement. Vinyl Ester cement, mortars is used in the construction of industrial floors, sumps, storage tanks, vessels and bleach towers in chemical processing, food and beverage plants, dairies, laboratories, textile, steel and pulp& paper mills.

SYNTHETIC RESIN CEMENT

These are a new class of resin cements with versatile and resistant to a wide range of chemicals. They are also popular owing to their rapid setting characteristics which make them preferred cements when time is a constraint or limited in a project or a maintenance job.

PHENOLIC RESIN CEMENT

Phenacin resin cement are the best acid resisting cement among resin cements including for high temperature service conditions. It is widely used in chemical, fertilizer and dye stuff industry.

SULPHER CEMENT

Sulphur cements are a single component,easy to use acid proof cement. Unlike other cements, it is applied in molten condition it does not require curing time. Hence they are more suited for maintenance jobs. They are extensively used in electrical insulators for fixing metallic parts on ceramics. They are also used in acid resistant masonry.

ACID RESISTANT COATINGS

We are a prominent manufacturer, supplier and service provider of Acid Resistant Coatings, Acid Proof Coatings, Chemical Resistant Coatings and Acid & Alkali Resistant Coatings. We provide excellent Anti Corrosive Coating services from India..

EPOXY COATINGS

Epoxy-resin based, for dry or wet conditions, on concrete, cement-coating or steel. Used for instance in the food industry (dairies, soft drinks), textile mills, chemical plants, power stations, refrigeration plants, warehouse, unloading areas, garages, concrete driving surfaces, supermarkets etc.

ACID RESISTANT MEMBRANES 

BITUMEN MASTICS

Bitumen mastics constitute the bulk of the membranes specified in a variety of service conditions except in the case of high temperature and solvent based environments.

MASTICS LINERS

Mastic compound is mainly used as an impermeable inter-liner with acid resisting brick/tile lining on floors, tanks, drains, sumps. It can also be applied, as open mastic flooring, where diluted chemicals are to be handled and traffic is not very high.

ACID RESISTANT EPOXIES

Acid resistant coating is used more in a technical sense with superior characteristics & results. The protective film thickness typically can range from 50 to 500 microns and rarely a 1000 micron thickness is specified due to the other service demands.

FLAKE LININGS

Flake Lining is a coating, consisting of glass-reinforced vinyl ester. The material has a very high chemical resistance and may also resist condensing sulfuric acidic gas. A preventive surface protection that will save maintenance costs.

RUBBER LININGS

The principal benefits of rubber lining are its excellent resistance to corrosive and abrasive chemicals and materials, e.g. acids, alkalis, salt water, slurries, sand, shot blast media, crushed rock etc. In addition rubber linings provide other benefits including noise and vibration reduction,electrical and thermal insulation and product protection.The rubber can be applied as either unvulcanised material which is then vulcanised and hot bonded – usually in a steam autoclave; or as pre vulcanised material which is cold bonded using two part adhesives. The fully bonded lining provides a durable and resilient protective rubber coating that will withstand very aggressive process conditions and applications.

ACID RESISTANT MORTARS

EPOXY BASED MORTAR

This is a polymer-based bonding paste used in agglomerate installation in the construction industry. The paste is a mixture of materials such as epoxy resins, solvent, binder, mineral fillers and some additives in certain measurements depending on the desired properties after curing. It is used as an adhesive and paste for structural repair. It can also be used to fill gaps, cracks and vents in driveways, patios and plazas. In setting tasks, it is used for tile installation where sealers are not required.

COROCEM MORTAR

COROCEM is an unsaturated Vinyl Ester resin based acid resistant cement used for both bedding and jointing and pointing of acid proof tiles / bricks. It combines the special advantage of rapid setting and hardening even under cold conditions, good mechanical strength and adhesion to tiles / bricks and stoneware.
