Lacquer & Insulation Varnishes
Lacquer is a transparent, hard, protective film primarily used in giving the final polishing to wooden furniture and other decorative fibers that are susceptible to decay in the long run. Lacquer is traditionally a combination of a drying oil, a resin, and a thinner or solvent. Lacquer produces a glossy luster. Lacquer has little or no colour, it is mostly transparent, and has no added pigment, as opposed to paints or wood strainers. It is also applied over wood stains as a final step to achieve a permanent glossy film for protection. Ideal furniture finish would penetrate deep into the substrate, dry quickly, provide good abrasion and stain resistance, good rub resistance and last but not the least, enhance the brilliance of the object.
Typically, modern commercially produced lacquer employs some form of alkyd blended with phenol resin to form a protective film. Phenol resin created out of CNSL origin produces a lacquer that is capable of superior water resistance, sturdy hardness, exceptional flexibility and standard alkali, grease and UV resistance. CNSL Lacquer is the best choice for furniture and decors that are designed for external purposes.
They can also reproduce a Protective finish coat that is filmed onto the outside of Tin Plates or Cans to protect their Surface from any Chemical Corrosion.
Insulating varnishes are generally clear varnishes formulated to have some special properties like fast drying, outstanding oil and chemical resistance, abrasion resistance etc. This varnish provides a smooth and glossy surface which is dirt resistant in its self. It may also be used as a coating for windings and mechanical components, for instance as an oil proof finish for field coils and starters or on the inside walls of control boxes. They have excellent flexibility and resistance to other chemicals along with very high gloss and adhesion properties.
