||An investigation into the composition of products evolved during heating of hot melt adhesives
||Jan. 1998, Vol.42, No.1, p.37-44. Illus. 12 ref.
||Analysis of the products generated during heating of a selection of 14 hot melt adhesives indicates the presence of a wide range of chemical compounds, including resin acids, volatile terpenes, aliphatic aldehydes, aliphatic and aromatic hydrocarbons and isocyanates. Some components, including resin acids and formaldehyde, are common to several types of adhesive, whereas others, such as acrolein and isocyanates, are specific to just one. There is no component which is characteristic of fume from all 14 adhesives. Concentrations of individual chemical components show significant variation both between different types of adhesive and between samples of the same adhesive heated to different temperatures or for different periods of time. For individual adhesives, concentrations of evolved material tend to increase as the temperature the of the glue is raised, with the highest levels being observed in samples taken directly after commencement of heating. Topics: acrolein; adhesives; aliphatic aldehydes; aliphatic hydrocarbons; aromatic carboxylic acids; aromatic hydrocarbons; formaldehyde; chemical analysis; isocyanates; melting; mists; pyrolysis products; sampling and analysis; terpenes; volatile substances.
