IS it possible to get occupational asthma from spaying fabric coatings eg scotch guard or fabricoat

I have a patient who thinks his asthma was caused by exposure to fabric coating as above. Are there any reports of an association

waterprrofing sprays containing PTFE have caused a wide range of mostly interstitial lung diseases, often following single exposures, but sometimes with features suggesting EAA. I believe that scotchguard contains a flurinated hydrocarbon similar to PTFE (perfluorobutanesulfonic acid). Fabricoat (at least according to a MSDS available on the net) contain an acrylate, a possible cause of occupational asthma. It would be best to get the MSDS's for the actual products used Anon, Sixty-four Michigan patients hospitalised or treated in emergency department with lung disease from waterproofing sprays, Project Sensor, 2008;19:1-3, Cormican LJ, Rees PJ, Hill Walkers’ Lung, Respiration, 2006;73:836-839, Wallace GMF, Brown PH, Horse rug lung: toxic pneumonitis due to fluorocarbon inhalation, Occup Environ Med, 2005;62:414-416, AKIHIRO T, KUNIHIKO I, TAKAHIRO T, HARUMI N, NAOKI M, TOMONORI H, MOTOYOSHI S, SHUNSUKE S, YOSHIAKI I, Acute Lung Injury Caused by Inhalation of Waterproofing Spray, Journal of the Japanese Respiratory Society, 2003;41:123-126, Yamashita M, Yamashita M, Tanaka J, Hirai H, Suzuki M, Kajigaya H, Toxicity of waterproofing spray is influenced by the mist particle size, Vet Hum Toxicol, 1997;39:332-334,
