RESIN MAKING

 

Synthetic resin started by the preparation of backlit. Leo H Baeckland is the pioneer of synthetic resin. Since that time hundreds of synthetic resins have been made and now many of giant industries are totally dependent on these chemicals. These are composed of many units which are called monomers and these monomers combine with each other by polymerization to make high molecular organic compounds. These units interlink by a serial of homogenous structure through a chemical reaction.

There are two groups of synthetic resins thermosetting and other one is thermoplastic resins. Thermoplastic resin can be mold resin3again while thermosetting resin can’t be mold which is the big difference between them. They can be synthesized in solid and liquid mode. Additives, catalyst, solvents play vital role in the making of resin.

In the case of phenol resin the main contents are phenol, Formaldehyde, oxalic acid and water. Phenolic resin can be used in reinforced plastic, automotive parts, electrical goods. Coating, piping and bottles manufacturing.

To make the urea formaldehyde resin’s solution which requires three basic contents that are Urea, formaldehyde and aqua ammonia. The processing of the UF resin is a different subject while it is used in the cellophane coating, adhesives and bulking the wood.

Modern applications  of Epoxy resins are used for decorative flooring applications such as terrazzo flooring, chip flooring, and colored aggregate flooring .There are different ways to make the products by resin materials such as blow molding injection molding and extrusion process  are well known methods.

                                                                   RESIN TYPES

Acrylate resin, acrylic resin, acrylic – a glassy thermoplastic; can be cast and molded or used in coatings and adhesives

Polyethylene, polythene – a lightweight thermoplastic; used especially in packaging and insulation

Allyl resin – a resin derived from allyl alcohol that hardens when cured; used as an adhesive

Resin, rosin – any of a class of solid or semisolid viscous substances obtained either as exudations from certain plants or prepared by polymerization of simple molecules

Urea-formaldehyde resin – a clear thermosetting resin made from urea and formaldehyde and used in electrical fittings, adhesives, and finishes

Alkyd, alkyd resin – a durable synthetic resin widely used in adhesives and paints

Phenolic, phenolic resin, phenoplast – a thermosetting resin

Epoxy, epoxy glue, epoxy resin – a thermosetting resin; used chiefly in strong adhesives and coatings and laminates

Melamine resin – a thermosetting resin formed from melamine and an aldehyde; used in molded products, adhesives, and coatings

Polyester – any of numerous synthetic resins; they are light and strong and weather resistant

Polymer – a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers

Polyvinyl resin, vinyl polymer, vinyl resin – a thermoplastic derived by polymerization from compounds containing the vinyl group
