Is Oxsol 100 is an EPA approved VOC exempt solvent? VOC-Exempt Solvents EPA regulations include a list of compounds that are explicitly exempted from regulation as VOCs, even though they are “compounds of carbon.” These include a short list of compounds such as carbon monoxide and carbon dioxide that historically have not been regulated as VOCs, and a longer list of compounds that EPA has classified as “negligibly reactive.” For instance, waterborne high-performance acrylics have been formulated to provide enhanced barrier performance Axalta Coatings (Core) 12395S-1. • Summarizing results for coatings in different classes o Two-component coatings o Single component air-dry coatings o Coatings containing exempt solvents • Validation of test methods • Analysis of high-boiling substances remaining in coating films B. PAINTS & COATINGS. Water Based Coatings When calculating VOC emissions for water based coatings, it is important that water is subtracted from the usage data before multiplying by a “minus water” VOC content figure (see Example 3). CONOSOL® 340 by Calumet Lubricants is a VOC-exempt, high-purity, low odor and toxic, aliphatic solvent composed primarily of C17 - C22 cycloparaffinic and isoparaffinic hydrocarbons. Exempt solvents, such as acetone and methylene chloride, are defined as those carbon TCEQ publication RG-404 Surface Coating Facilities: A Guide for Obtaining Air Authorization in Texas Q. Appendix G: EPA Regional Office addresses for information and sending notifications, reports, and fees : Appendix H: Worksheets for estimating and computing total mass of VOC … VOC Exempt Solvents Contact Us Customers are needing to formulate VOC’s (Volatile Organic Compounds) out of their formula because of continual state and federal reductions in the amount of VOC’s that can be found in paint. Chemicals Ltd. Propylene Carbonate is a clear VOC-exempt solvent per the South Coast Air Quality Management District (SCAQMD). high-performance coatings BASF’s selection of high-performance solvents enables coatings formulators to maximize performance. Elvacite® 4144 – High solids, low VOC coatings. with VOC stringency, three of the positive strategies from the vanguard of coating formulators have been the advent of innovative waterborne coatings, high-solids coatings that con-tain exempt solvents, and solvent-free coatings. Click for sample or quote. Evaporation is necessary as part of the drying process as well as to control the coating viscosity at different stages of drying. The VOC contents of paints and ancillary products are regulated by the Volatile Organic Compounds VOC in Paints, Varnishes and Vehicle Refinishing Products Regulations 2012:1715.These cover the decorative and vehicle refinish sectors. When a solvent is said to be "exempt," it qualifies or is exempted. coatings : Appendix F: When do I include or exclude water, exempt compounds, and colorant from my coating VOC and volume calculations? A. Oxsol 100 (PCBTF), t-butyl acetate (TBA), acetone, volatile methyl siloxanes and methylene chloride are exempt as VOCs by the EPA. Elvacite® 4149 – High solids, low VOC coatings. Low VOC Capability Joncryl polyols for solvent-borne coatings are designed to ensure compliance with government VOC regulations and ingredient restrictions. Higlyme VOC-exempt in Europe 6% VOC in the United States Most powerful emulsifier Acetone is on the Federal exempt solvent list - not just California. • 30 pounds per hour of VOC and 5.0 pounds per hour of exempt solvents. exempt in Canada, but Environment Cana-da has indicated that it will consider ex-empting it as part of its architectural and industrial maintenance coatings regula-tion. If Environment Canada decides that TBAC is not photochemically reactive, it will likely be VOC-exempt by … Criteria for Solvents (PDF) (14 pp, 314 K) Criteria for VOC-exempt Solvents (PDF) (1 pg, 22 K) Contact Us to ask a question, provide feedback, or report a problem. What other solvents are EPA approved VOC exempt other than TBA for coating manufacturing? Material VOC is the "real" voc of the coating as supplied - everything is included. • Effective 9/30/09, TBAC is VOC-exempt in Canada for architectural and automotive coatings • US and Canadian Regulations based on photochemical reactivity – Only photochemically reactive compounds are regulated – Negligibly reactive compounds are exempt: • Acetone, methyl acetate, TBAC, many halogenated solvents. Elvacite® 2044 – Softest, most flexible bead grade. Conformal. In coatings, the solvent must dissolve the resin and reduce its viscosity so it can be applied (either by spray or brush). This is done to regulate the ratio of solids to VOC in the coating formulation since it is the VOC portion that contributes to air pollution. Methyl acetate, a VOC-exempt solvent in the U.S. Waterborne adhesion promoters, both chlorinated and nonchlorinated, designed to provide excellent adhesion to modified polypropylene substrates and other plastics; Resin intermediates for developing resins that are useful in powder, high-solids, or waterborne coatings Excellent acetone solubility. Helping formulators keep up with global demand for products low in or free of volatile organic compounds (VOCs), AMP continues to gain traction as an approved and reliable sustainable chemistry solution—having earned VOC-exempt status from some of the world’s most respected environmental governing bodies. They are so volatile and flammable that they have found only limited use, despite their VOC-exempt status. Higlyme and proglyme are powerful co-solvents that strongly complexes with pigments in coating formulations. Low VOC solvent useful with paints and coatings Download PDF Info Publication number US20070101902A1. S.A.F.E. So solvent blends (no solids)use the material VOC. How about that in Texas? Items Per Page. While our suppliers provide VOC data, we still have to derive the VOC content of the coatings as applied since we may add solvent and/or water to the coatings. Formulating with Exempt Solvents seldom used in the coatings industry because of their corrosiveness, poor solvency, toxicity, cost and odor. There are only two nonhalogenated exempt solvents, acetone and methyl acetate. In coating materials of less than 1 pound of solids per gallon the material VOC is used. A common approach to lower VOC content in solvent-based alkyd coatings is to use exempt solvents, such as acetone, methyl acetate, parachlorobenzotrifluoride (PCBTF), octamethylcyclotetrasiloxane (D4 cyclic siloxane), and tert-butyl acetate. Shrieve has industry-leading expertise in the supply of VOC (Volatile Organic Compound Classification) exempt solvents.Shrieve is working to be at the forefront of the Paint and Coatings industry presenting vision and insight into the global options for raw material sourcing.

This information will be used to calculate the VOC content of the mixed coating. Broad compatibility with VOC exempt solvents. Thus, the 55% decrease (from 5.70 to 2.58) in VOC content calculated by the "per-pound-ofsolids" method reflects the actual reduction in VOC emissions obtained by using a VOC-exempt solvent. Axalta is a leading global company focused solely on coatings and providing customers with innovative, colorful, beautiful and sustainable solutions. An exempt solvent is a particular type of solvent that falls below specific safety criteria. 8 Other VOC Exempt Solvents • In the United States today there are few VOC exempt solvents that are not HAPS (or ODS) and even fewer that can be purchased for less than $2.00/lb to allow formulators an option for low cost formulations for the coating, cleaning & adhesive markets. compounds’, ‘VOC as applied’, or ‘VOC EPA Method 24’ Percent Water and Exempt Compounds Collecting two of the three above items for each component is sufficient.
