SOYA  LECITHIN

A WONDER PRODUCT FOR PAINTS, PRINTING INKS AND COATINGS

DESCRIPTION :

Soya lecithin is extracted from soyabean oil by a process known as degumming .

It is also obtained from soyabeans by solvent and steam extractions .

It is semi liquid yellow to light brownish product, insoluble in water but soluble in oils and alcohols.

It is a glyceride of complicated chemical structure containing an amine, phosphoric acid and chlorine.

It is a complex mixture of phosphor lipids similar to those found in all living animals and vegetable cells.

As soya lecithin is totally a natural product, slight variations in characteristics can occur.

FUNCTIONAL PROPERTIES :

It has unique functional properties as emulsifier , wetting agent , blending aid ,disperser , stabilizer and viscosity agent so it makes itself an important part of formulation for paint and inks .

It has specific functional qualities due to its amphiphilic chemical composition . The surface active phosphoric molecules , which from the major constituent of lecithin have both hydrophobic (water attracting) portion .

Chemically incompatible ingredients can also be emulsified because of the polar and nonpolar components of lecithin . Hence it is capable of stabilizing both oil in water and water in oil emulsions.

As it is derived from a completely natural source , it is attractive for industrial manufacturers where a non – chemical ingredients profile is a priority .

GENERAL FUNCTIONS :

Emulsifier – stabilizes Oil – in – water and water – in – Oil emulsions .

Disperser & Wetting Agent – rapidly disperses powders in aqueous systems .

Blending aid – reduces mixing time to incompatible ingredients i.e. polar and non – polar .

Viscosity agent – reduces friction by coating particles .

APPLICATIONS IN PAINT AND PRINTING INKS :

1. It imparts flow in printing inks and works as wetting agent .
2. Lecithin concentrate produced from soya can be used as stabilizer in water based paints to prevent pigment migration and settling in storage .
3. It is employed in casein paints to regulate viscosity .
4. Concentrated grade of soya lecithin containing 68% active ingredients can be used as low moisture emulsifier for coatings and paints .

RECENT DEVELOPMENTS :

Water soluble grades of soya lecithin and powder grade of soya lecithin are also produced in india.

Eco friendly soy lecithin emulsions for special applications are also available.

                                         DISPERSING AGENT  :  EDENOL

Today Polyethylene Waxes are used for pigment dispersion  taking advantage of their low melting temperature , which only smears the pigment but would not penetrate into the pigment molecule due to its inert hydro carbon chain. On the other hand , we under the guidance of our technocrats with 20 years of experience in “ Research and Development ‘’ have developed EDENOL which carries compatible functional groups which solubilize the pigment  and plasticise the polymer yielding higher colour depth and brightness with better physic mechanical properties of ink and master batch as has been referred for LOZIOL G 31 marketed by Henkel International Gmbh .

ADVANTAGES :

EDENOL with excellent  WETABILITY , converts these pigment agglomerates into fine uniform DISPERSION without damaging the colour brightness & depth. Simultaneously EDENOL imparts :

          Smooth silky surface                            Higher  Elongation

          Better output                                         Brittleness free at low temp .

          Non toxicity , recommended for good grade

Zinc Borate

ZB is a flame retardant / smoke suppressant in polyamides, PVC, polyethylene, polypropylene, epoxy, polyesters, elastomers and rubber based formulations. The particle size and refractive index of ZB results in the product having very little pigmenting power (tinting strength), minimizing pigment loading and in translucent formulations.

CHEMICAL STRUCTURE

Zinc Borate

CAS Reg. Number [1332-07-6]

APPLICATIONS

ZB also finds applications as an afterglow suppressant and anti-arcing agent. The product is recommended for most thermoplastics including polyamides, where the high thermal stability allows processing up to 280°C. It is also recommended for polyurethanes thermoset resins, plastisols, adhesives and cellulosics and textiles coating applications.

STORAGE AND HANDLING PRECAUTIONS

The use of proper protective equipment is recommended. Excess exposure to the product should be avoided. Wash thoroughly after handling. Store the product in a cool, dry, well-ventilated area away from incompatible materials.

Unless stated, proper storage will permit usage of the product for 6 to 12 months from the date of receipt.

It has been observed that ALUMINA HYDRATE improves the finish of dried ink films. If gloss varnish can be used, the addition of same increases the finish still further. A combination of hydrate and gloss varnish is frequently used

Because the ALUMINA HYDRATE has acidic properties, it does not change appreciably the acidity of the lithographic fountain solution during the printing operation. The hydrate is therefore a useful ingredient in lithographic inks.

In multicolour printing where inks trap over each other, it is obviously an advantage to have transparent inks after the first one. ALUMINA HYDRATE qualifies very well as a transparent extender when an ink needs to be reduced in colour strength for multicolour printing

The majority of the moisture-set inks (often called steam-set inks) contain a resin that is very acidic in nature. This resin is a fumarated resin and has an acid value that is over 300.

In a number of inks, a blend of clay and ALUMINA HYDRATE can be used as the extender to arrive at a low cost and acceptable printing qualities. However, if the printing run be a long one, it is safer to select a good printing extender to prevent piling on the rollers and on the printing plates.

More present day pigments are faded or changed in hue by alkaline substances than by acidic ones. The majority of the Triphenylmethane and Diphenylmethane pigments, such as Methyl Violet and Alkali Blue, shift their chemical structures to the colourless state when alkali is present.

The popular Iron Ferrocyanide Blues readily fade with alkalies. The use of ALUMINA HYDRATE , is a safeguard in cases where alkaline materials can be activated by the presence of sufficient moisture that can yield fading of sensitive pigments.

1512 ALUMINA HYDRATE has a reduced reactivity. An accelerated test can be conducted of the ink at 160 o F during three days to examine the possibility of livering, either on storage or during hot milling.

Many of the resins that formerly livered with ALUMINA HYDRATE have in the recent years been improved so liv thatering has been eliminated. Therefore, the selection of Hydrate can be made in many resinsolvent in inks that formerly could not tolerate this extender

Paints, Printing Inks and Coatings based on oxidizing type polymers such as oil modified alkyds, phenolic  maleics, fatty acids may undergo it can polymerization in the presence of air and drier, causing severe  problems of skin formation. 

Skinning is frequently encountered in filled to the brim. Frequent openings of lid allow air to remain  present in the void, leading to oxidative polymerization at the interphase. This in turn leads to  formulation of solid skin during storage, at times, so severe that the most part of coating is rendered  Useless. 

Loss in coating due to skinning is a loss which can always be avoided. AS such skinning loss is estimated  to be approx 3-5% of the total wt. of coating. Manufacturers of Paints, Printing inks and coating who  supply their products in small packing’s are most badly hit economically due to skinning. 

THE SOLUTION TO THE PROBLEM: “SKINNIL” is highly effective and ideal anti-skinning agent which  shows remarkable improvement over many other commercially available anti skinning agents for inks  and coatings. 

STAHE OF INCORPORATION: To be added on the premixing stage of the ink in the premixer itself or it  can added in offset varnishes also. 

MECHANISM: SKINNIL is capable of temporarily complexing oxygen and does not allow oxidative  polymerization on inter phase. At the same time it is compatible with wide range of resin vehicles. 

CHARACTERISTICS: 

1) SKINNIL has solvent compatibility. 

2) SKINNIL is inert to react with other ingredients of ink and paints. 

3) SKINNIL has a high potency and small addition is sufficient to retard skinning due to oxidation. 4) SKINNIL neither affects the rheological properties of paint/ink nor 

5) The durability of the resultant film.

6) SKINNIL in non-toxic and odorless. 

7) SKINNIL is non yellowing.
