Agglomerated cork stoppers were finished with two different doses and using two surface treatments: P (paraffin and silicone), 15 and 25 mg/stopper, and S (only silicone), 10 and 15 mg/stopper. FTIR spectra were recorded at five points for each stopper by attenuated total reflectance (ATR). Absorbances at 1,010, 2,916, and 2,963 cm -1 were obtained in each spectrum. Discriminant analysis techniques allowed the treatment, and dose applied to each stopper to be identified from the absorbance values. 91.2% success rates were obtained from individual values and 96.0% from the mean values of each stopper. Spectrometric data also allowed treatment homogeneity to be determined on the stopper surface, and a multiple regression model was used to predict the friction index (If = Fe/Fc) (R 2 = 0.93) date: 2012 date_type: published official_url: http://download.springer.com/static/pdf/373/art%253A10.1007%252Fs00226-011-0403-5.pdf?auth66=1394627684_587a25fbfebab641abedf774381f26f6&ext=.pdf id_number: 10.1007/s00226-011-0403-5 full_text_status: public publication: Wood Science And Technology number: 46 pagerange: 349-360 institution: Montes department: Ingenieria_Forestal refereed: TRUE issn: 0043-7719 rights: by-nc-nd citation: Gonzalez Adrados, Jose Ramon and García Vallejo, Mª Concepción and Cáceres Esteban, Mª José and García De Ceca, José Luis and González Hernández, Florentino and Calvo Haro, Rosa (2012).
