Solbin® C

Product Characteristics:

  • Soluble in ketones, esters and chlorinated hydrocar-bons. Use aromatic hydrocarbons as diluent solvents. Insoluble in alcohol, oil and aliphatic hydrocarbons.
  • Chemically stable and is unaffected by acids and alkalis at normal temperature.
  • It combines high water resistance with low moisture permeability and low water absorption.
  • Tough, resilient and non-flammable.
  • Solbin C is colorless and transparent with a high refraction index, it can be changed into any bright color and produces a highly glossy film.
  • It possesses an excellent ability to resist the effects of weather and aging.
  • As a thermoplastic, films made with Solbin C can be easily heat sealed.

Solbin C is a thermoplastic resin consisting of polyvinyl chloride (VC) and polyvinyl acetate (VAc).

  • Metal Protective Paints—Excellent non-corrosive properties.
  • Metal Container Paints –Its anti-corrosive properties makes it an excellent choice for lining food and beverage containers, including applications for medicines and cosmetics. It produces a tough film that makes it ideal for coating steel and galvanized tin plates that will be fabricated later.
  • Paper and Textile Coating-Provides a waterproof protection, adding gloss for a better decorative effect.
  • Ship Paints— Exceptionally high anticorrosive properties make it ideal for topcoat as well as wash primer and second coat applications.
  • Cellophane coating—SOLBIN C is damp-proof making its film readily heat sealed ideal for coating cellophane.
  • Concrete and Plaster Paints— Coating the walls of quays.
  • Adhesives—PVC and Blister packages.
  • Plastic coatings—Adds gloss to both coating and printing on plastic.

How to Use:

  • To ensure Solbin C quickly goes into solution it is recommended to disperse it into a weaker solvent such as toluene and xylene then blend with the stronger solvent.
  • Solbin C is usually dissolved in a combination of both ketone (e.g. MEK and MIBK) and aromatic hydrocarbon (e.g. toluene and xylene) solvents in equal proportions, to produce a solution of 15%-20% concentration by weight. For coatings on a porous substance, (paper or cloth), faster drying solvents such as MEK and acetone are recommended.
  • For Spray coating, MIBK is used. For baking on metals, ketone with a high boiling point such cyclohexanone is used. For roll coatings, cyclohexanone or isophorone are
  • sometimes used. Heating to around 50°C and sufficient agitation are required to speed up dissolving.
  • In order to provide proper flexibility, resilience and adhesiveness to film, 5-20 PHR of plasticizer are added. The kind and amount of plasticizer to be added can be determined in the same manner as in the method of blending polyvinyl chloride resins.
  • Most common pigments can be employed.
  • Stabilizers against heat and light are used, as with conventional polyvinyl chloride resins. The addition of about 0.2% propylene oxide, in this case, can prevent the corrosion of containers and change in paints in storage.
  • Any method of coating, including spraying, roll coating and others, may be used. For roll coating, a solution of 200-400 seconds in Ford Cup No.4 viscosity should be used. For Spray applications a solution of 60-80 seconds Ford Cup No.4 viscosity should be used at an air pressure of 98-100psi and a liquid pressure of 20-30psi.
  • Solbin C does not usually provide satisfactory adhesion through air drying alone. The following chart provides the degree of adhesion to various surfaces by air drying:
  • Short-time baking at 170-190°C will significantly improve ad- hesion and surface gloss. When primers are used, sufficient adhesion may be obtained without baking.



Solbin C is highly soluble in organic solvents such as ketones, esters, and chlorinated hydrocarbons.
