WebThere are several base (or basic) chemicals that are the building blocks in the manufacture of petrochemical products: ethylene, propylene, butadiene and the so-called aromatics (benzene, toluene and xylenes). These basic chemicals are themselves derived from the constituents of crude oil and natural gas - as shown in this table: WebThe aromatic solvents available from Shell chemicals companies include pure aromatics like toluene and xylene (isomer mix) as well as a range of heavier C9 and C10 aromatic …

Due to quick evaporation, it’s perfect for projects needing fast drying times. Acetone is very effective as a thinner, cleaning solvent, or remover for fiberglass resins, polyester and epoxy resins, adhesives or contact cement, ink, latex paint, and uncured lacquers. ontario oas eligibility
