Epoxy Resin (CAS No. 55818-57-0, Common For Bisphenol‑A Based Epoxy) Is A Thermosetting Polymer Formed By The Reaction Of Epichlorohydrin With Bisphenol‑A Or Other Polyols. Its General Molecular Formula Is C21H25ClO5 (Variable Depending On Chain Length). Synonyms Include Epoxide Resin, Bisphenol‑A Epoxy Resin, And Thermosetting Epoxy. Appearing As A Viscous Liquid Or Solid Granules, It Is Widely Used In Coatings, Adhesives, Composites, Electrical Laminates, And Construction Materials. Epoxy Resins Cure With Hardeners (Amines, Anhydrides) To Form Cross‑Linked Networks With High Mechanical Strength, Chemical Resistance, And Adhesion.

Polyester Resins  Are Synthetic Polymers Formed By The Polycondensation Of Polyols And Dibasic Acids. Synonyms Include Unsaturated Polyester Resin (UPR), Saturated Polyester Resin, And Thermosetting Polyester. Appearing As Viscous Liquids Or Solid Granules, They Are Widely Used In Coatings, Composites, Adhesives, Laminates, And Molded Products. Unsaturated Types Are Cross‑Linked With Styrene To Form Fiberglass Reinforced Plastics (FRP), While Saturated Types Are Used In Powder Coatings And Films.

Ketone Formaldehyde Resin  Is A Thermoplastic Condensation Resin Produced By Reacting Cyclohexanone (Or Other Ketones) With Formaldehyde. It Appears As A White To Pale Yellow Granular Solid With A Softening Point Typically Between 90–120°C. Synonyms Include Cyclohexanone Formaldehyde Resin, KFR, And Ketone Resin. It Is Soluble In Organic Solvents Such As Alcohols, Esters, And Aromatic Hydrocarbons. KFR Is Widely Used In Printing Inks, Coatings, Adhesives, And Varnishes, Valued For Its Excellent Solubility, Gloss, Adhesion, And Chemical Resistance.

Vinyl Ester Resin Is A Thermosetting Resin Formed By The Reaction Of Epoxy Resins With Unsaturated Monocarboxylic Acids (Commonly Methacrylic Acid). It Appears As A Viscous Liquid, Curing Into A Tough, Chemically Resistant Polymer When Cross‑Linked With Styrene Or Other Monomers. Vinyl Ester Resins Combine The Mechanical Strength Of Epoxy Resins With The Rapid Curing And Corrosion Resistance Of Polyesters.

Petroleum Resin Is A Thermoplastic Hydrocarbon Resin Derived From The Polymerization Of C5, C9, Or DCPD (Dicyclopentadiene) Fractions Obtained During Petroleum Cracking. It Appears As A Yellow To Brown Granular Solid With Softening Points Typically Ranging From 80–150°C. Synonyms Include Hydrocarbon Resin, C5 Resin, C9 Resin, And DCPD Resin Depending On Feedstock. Petroleum Resins Are Widely Used In Adhesives, Paints, Coatings, Rubber Compounding, Printing Inks, And Road Marking Paints, Valued For Their Tackifying Ability, Compatibility With Various Polymers, And Chemical Stability.
