Aromatic Solvent C9

Aromatic hydrocarbons are a series of organic molecules that form flat ring-shaped bonds.  Aromatic hydrocarbon C₉/C₁₀/C₁₂ resins are conventionally named because they are defined by the number of carbon monomers in the chemical.  Aromatic hydrocarbons have a distinctive aromatic odour and a typical Gardner colour of 6 – 10 (dark yellow to dark brown).  They are insoluble in water, low alcohols and ketones, however are soluble in aliphatic hydrocarbons and chlorinated hydrocarbon solvents.

Production

Aromatic hydrocarbon resins are chemically manufactured from resin oil that contains various monomers.  The end product is combination of the following chemicals: indene (20-25%), methlinenes(5-15%), vinyltoluenes(15-25%) and a-methylstyrene (up to 5%).  They are based on aromatic feedstocks that do not undertake much refinement prior to the above polymerisation process.

Storage and distribution

A chemical trader would have a bulk petrochemical storage facility to regulate this product.  Storage is normally in a cool, dry and well ventilated facility away from oxidising agents.  Solvents such as the aromatic hydrocarbons should be stored in drummed containers such as isotanks made of stainless steel, aluminium or carbon steel.

A bulk solvent exporter would normally distribute this solvent in bulk vessels or tank trucks.  For transportation purposes, aromatic hydrocarbons are classed as a flammable liquid with a fire hazard rating of 2.  A full bulk chemical distributor would export the solvent throughout regions such as the UK, Europe, Africa and America.  This product is a packing group 3.

Uses

Aromatic hydrocarbons are mainly used in adhesives, printing inks, sealants, polychoroprene rubber, concrete curing compounds, anti-drying agents and paints.  They have a good compatibility with SBR, SIS, SEBS and SEPS and can be used as a pressure sensitive adhesive, hot-melt adhesive and synthetic rubber.  They can also be applied to coatings on ships, vehicles and bridges because they will improve the lustre, increase hardness and make areas more water resistant.  Within the printing industry, the petroleum resin will increase water resistance, solvent consumption and resistance to dry.  They are also used for hot road markings.  The end user markets for this product are the paints, coatings and rubber industries.
