The papaer discusses the characterization of emissions from conversion varnishes. Three commercially available conversion varnish coating 'systems' (stain, sealer, and topcoat) were initially scoped. Total volatile content of the catalyzed varnishes (determined by EPA Method 24) ranged from 64 to 73 weight %. Uncombined (free) formaldehyde concentrations (determined by sodium sulfite tritration) ranged from 0.15 to 0.58 weight % of the resin. Each resin was also analyzed by gas chromatography/mass spectrometry (EPA Method 311) to identify the volatile components that may be emitted. Dynamic small chamber (53 L stainless steel) tests identified and quantified emissions following application to coupons to typical kitchen cabinet wood substrates and during curing and aging. An objective was to determine the relation between the concentration of hazardous air pollutants (HAPs), volatile organic compounds (VOCs), and formaldehyde in the resins and emissions from the catalyzed varnish. Results to data show good mass balance for the HAPs and VOCs.
