Solbin® AL

Product Characteristics:

  • Soluble in ketones, esters and chlorinated hydrocarbons. Use aromatic hydrocarbons as diluent solvents. Insoluble in alcohol, oil and aliphatic hydrocarbons
  • Films made from Solbin AL are tasteless, odorless, and unaffected at room temperature by alkalis, mineral acids, alcohol, oil and aliphatic hydrocarbons.
  • It combines high water resistance with low moisture permeability and low water absorption.
  • Offers superior mechanical properties such a anti-abrasion, flexibility and non-tackiness.
  • Imparts good, stable dispersibility to pigments and magnetic powder in paints and in dried layers even at high packing density.
  • Provides a wide choice for coating formulations due to its compatibility with various resins including polyurethane, epoxy resins, NBR, isocyanate, etc.
  • Reacts with organic groups such as isocyanete to form cross linking.

Solbin AL is a thermoplastic resin consisting of polyvinyl chloride (VC) , polyvinyl alcohol (VA) and polyvinyl acetate (VAc). Due to its lower molecular weight than Solbin A, it provides lower solution viscosity.

  • Printing Ink – Solbin AL is used for coating and gravure printing ink, adding gloss to create a better decorative effect.
  • Metal Container Paints – Solbin AL is used for lining food and beverage containers. Its anti-corrosiveness makes it an excellent choice for use in container lining, 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 – Solbin AL provides a water-proof protection, adding gloss for a better decorative effect.
  • Magnetic Paint-Due to Solbin AL’s excellent dispersing ability for inorganic pigments such as magnetic powder, it is used as a binder and dispersing agent for magnetic paint used to produce video tapes, audio tapes, mag- netized cards and floppy disks.

How to Use:

  • To ensure Solbin AL 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 AL 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 blend- ing 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 AL 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 adhesion and surface gloss. When primers are used, sufficient adhesion may be obtained without baking
