Dicyclopentadiene, abbreviated DCPD, is the dimer of cyclopentadiene (CPD). In the pure state DCPD is a volatile solid with a characteristic odour. Dicyclopentadiene is coproduced in large quantities in the steam cracking of naphtha and gas oils to ethylene. In addition, it can be prepared in a Diels-Alderreaction of 2 cyclopentadiene molecules.
Most dicyclopentadiene is used as co-monomer in the production of synthetic resins, in particular unsaturated polyesters and synthetic rubbers, for example EPDM. Poly (DCPD), which contains some dicyclopentadiene as monomer is used in printing inks and engineering plastics.

Melamine is an organic compound with the formula C3H6N6. It is a polyvalent organic base. Melamine structurally consists of an aromatic ring composed of 3 carbon and 3 nitrogen atoms. Melamine is the cyclic trimer of cyanimide.
Melamine is mainly used as raw material for melamine resins and coatings. By a reaction with aldehydes (usually formaldehyde) thermosetting plastics can be produced. Melamine-formaldehyde is strong, light, hard and resistant to acids and bases.
