Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Cleaning: 5 min. immersion cleaning at 120 F with stir-bar agitation.
Rinsing: 1/2 min. manual with water at 120 F
Drying: 1 min. with heat gun at 500 F
Contaminant: Latex Binder Mix
Cas #: 9016-45-9, 79-06-1, 7664-41-7, 924-42-5, 50-00-0, 1333-86-4, 57-55-6, 7732-18-5
floroacrylate copolymer emulsion, Linear alkyl benzene sulphonate
Observation:
1. Cleaning Latex Binder with DS-108-Solvent big pieces of binder were removed as compared to the other cleaners and the solvent remained on the coupons even after rinsing which led to the increase in the weight.
2. There was no removal of binder by Tarksol HTF-60. Instead, there were pockets formed which retained the cleaner which led to tremendous increase in weight.
