AUXI IN UDI

AUXI IN UDI can be applied both in the exhaust bath as well as in padding processes. In the exhaust dyeing of reactives and vats prior addition of 1-2% of AUXI IN UDI in the dyebath prevents Ca and Mg ions interfering with the dyeing process, particularly when using hard water.In the dyeing of reactives by cold pad-batch process the addition of 2-3 gm/I AUXI IN UDI in the padding solution gives dyeing with good levelness and solidity for the same reason. Addition of 2 gm/I AUXI IN UDI during the washing of reactive dyeing helps in the rapid removal of unfixed dye. This leads to improved rub fastness of the dyeings. Additionally, during washing-off of cold pad-batch dyeings the addition of 2 gm/I of AUXI IN UDI in the washing bath helps in the quick removal of sodium silicate from the fabric.

Properties Suppliers
Kemklin-106

Kemklin-106 is a phosphoric acid base chemical, mixed with different types of acids which is specially formulated to remove heavy rust and scales effectively by hot dipping process. Kemklin-106 is an inhibited acidic compound, which is suitable for removing the rust from ferrous metal surfaces. It also removes the oxide film rapidly and promotes good phosphate coating adhesion. It requires no expensive equipment for operation.

Properties Suppliers
Kemklin-109

Kemklin-109 is specially formulated to remove mild rust from ferrous and non-ferrous metals effectively by spray process. Kemklin-109 (S) is purely based on phosphoric acid enriched with various types of solvents/surfactants and wetting agents, etc. Kemklin-109(s) attacks only on rust or scales and it does not attack on the base metal.

Properties
Kemlube-122

Kemlube-122 is solvent base rust preventive fluid having excellent water displacing properties for short term protection period. It is specially recommended after the pickling operation.

Properties Suppliers
Kemlube-202

Kemlube-202 is an acid inhibitor and is used to minimise the attack of sulfuric acid during pickling. During pickling, the metal gets dissolved in concentrated bath which causes pitting on the metal. To avoid pitting, kemlube-202 is used in sulfuric acid bath.

Properties
Kemlube-203

Kemlube-203 is a surface wetting agent generally used in Hcl/h2SO4 acid. The purpose of using Kemlube-203 is to minimize the hazardous fumes eliminating the need of heavy duly exhaust arrangement.

Properties
Kemlyte-222

Kemlyte-222 is a specially formulated chemical to eliminate contaminants from the pretreatment of metal surfaces and also to give chromium free coating to avoid attack of oxides, chlorides, etc. present in the air.

Properties Suppliers
Kemphos 326

Kemphos-326 is an accelerated Zinc phosphating process, which is specially formulated to produce medium to heavy weight coating on Iron and steel surfaces by hot immersion method. Kemphos-326 is recommended for wide range of ferrous metal articles such as car accessories, metal cores, forge and cast iron components, small component parts such as nuts, bolts etc. Kemphos-326 protects iron and steel surfaces from rusting. Medium weight coating gives a very good foundation for paint system and protects under film corrosion. Heavy weight coatings provide excellent base for stains and are also recommended for small component parts for rust protection with minimum build up on thread parts.
