THINNER FOR INDUSTRIAL USE

THINNER FOR INDUSTRIAL USE WITH Thinner for Acrylic Paint, Thinner for Enamel Paint, Thinner for PU Paint, Thinner for Epoxy Paint, NC Thinner

Thinner is a hydrocarbon (naphtha) or oleoresinous solvent (turpentine) used  to reduce the viscosity of paints to appropriate working consistency usually just  prior to application. In this sense, a thinner is a  liquid  diluent  to except that it has active solvent power on the dissolved resin.

“Thinners” as the name implies, are added to varnishes and lacquers to thin them out usually to brushing consistency. White spirit is the commonest liquid used for this purpose. A thinner differs from a diluent in that it has solvent action on the dispersed resin or other solid and will not as a role cause precipitation.

Solvents or Thinners are used in Paints and lacquers to reduce the viscosity and consistency of the material and facilitate the application of a uniform coating. They must be compatible with the oil or resin present. After application the solvent is no longer required and should evaporate completely from the film.

Thinners are employed for adjusting the consistency  of coating  formulations.  Turpentine was formally used as thinner for resin and oil coatings.  It has been replaced by petroleum naphtha (boiling range, 300-400^oF) and varnish  maker’s and painter’s naphtha (VM & P naphtha). Water is used as a thinner in  emulsion paints, water colours and calcimines. A wide range of solvents possessing specific properties are now used in formulations containing synthetic resins.

According to their boiling ranges, solvents are classified as low boiling (b.p., <100o), medium boiling (b.p., 100-120^o), and high boiling (b.p.,<150^o).  A blend of solvents from the three groups is commonly used.

Organic solvents used in the formulation of nitrocellulose lacquers  may be considered under three classes: true solvents, latent  solvents,  and  diluents.  Esters,  ketones, and glycol ethers and true solvents; those in common use are: accetates of methyl, ethyl, isopropyl, and sec-butyl, and amyl alcohol, propionates of butyl and amyl alcohol; lactates of  ethyl and butyl  alcohol  acetate of glycol ether;  acetone,  emthyl  ethyl ketone,  methyl isobutyl ketone, diacetone alcohol, cyclohexane, and isopropane. Latent solvents comprise various alcohols which behave  as true solvents in the presence of esters  and  ketones, aliphatic and aromatic hydrocarbons are used as diluents.

A  wide range of solvents possessing specific properties are  now  used  in  formulations containing synthetic resins. According to their boiling range,  solvents are classified as low boiling  (B.P.  100^o) medium boiling (B.P.  100-120^o),  and high boiling (B.P. 150^o).

The solvents and thinners used in making varnishes are :

1. Turpentine.
2. Kerosene.
3. Dipentene.
4. Naphthas (Aliphatic)
5. Naphthas (Aromatic)
6. Xylol.
7. Toluol
8. Alcohols.

These help to dissolve and control viscosity of filming material.

Market:

The main consuming industries for thinners and solvents are paints and varnish industries.

India’s current  consumption of  paints per capita is fractional at 0.23 kg and this is, not with standing, the fact of our being the tnth in the order of  industrially developed countries when compared to eighteen to twenty  kilogram consumption per capita in the developed countries. However in the future the demand of paints is likely to go up.

As the paint industry is a major consumer  of  thinners  & solvents,  and  is expanding at a tremendous speed, it is very obvious that the demand of  thinners,  too, will increase tremendously.

Also, it is surmised that, with the growing automobile market and  industrialization,  as a result  of  liberal  policy measures,  the paint industry is likely to have a better rate  of growth.  The growing urbanization also would help  in  generating the higher demand level.

With all the above perceptions it can be visualized that thinners and solvents have a good demand in the market.

FY14 was tough for the Indian paint sector. Hopes of a revival in demand after a good monsoon and during the festive season were dashed by high inflation. The demand for paint, being a discretionary expenditure, is typically hurt during periods of rising inflation. However, to their surprise, paint makers have found that while demand remained tepid in cities, consumption was rising in rural areas. The increasing reach of media in villages has also helped paint makers, making easier for them to advertise their products in these regions. Companies have also discovered that demand for premium paints is high even in remote locations.

Performance on the margins was impacted by the rising prices of crude oil and titanium dioxide which increased the overall expenditure, thereby impacting profitability growth. However, companies are undertaking a gradual and calibrated price increase in order to shield margins. Nonetheless, as a complete pass on of raw material price increase is not possible in the industrial segment, the blended margins continue to suffer. A good harvest and festival season demand can boost volumes in the second half of FY15.

The paint industry is expected to grow at 12-13% annually over the next five years from Rs 280 bn in FY13 to around Rs 500 bn by FY18. FY14 was a challenging year for the industry as a whole due to subdued demand across key sectors and rising inflation.
