Ketone Formaldehyde Resin
Acetophenone is the organic compound with the formula C6H5C(O)CH3. It is the simplest aromatic ketone. This colourless, viscous liquid is a precursor to useful resins and fragrances.
Petroleum resin is a C5/C9 aromatic hydrocarbon used in industrial applications. It has a tackifying effect and is suitable for use in paint, printing ink, adhesives, rubber and other areas where tackiness is required
Phenol Formaldehyde Resin
The earliest commercial synthetic resin is based on a phenol formaldehyde resin (PF) with the commercial name bakelite, and is formed from an elimination reaction of phenol with formaldehyde phenol is reactive towards formaldehyde at the ortho and para sites (sites 2, 4 and 6) allowing up to 3 units of formaldehyde to attach to the ring. This forms a hydroxymethyl phenol.
Polyester resins are unsaturated resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Among other uses, it is the basic component of sheet moulding compound, bulk moulding compound and the toner of laser printers.
