Luan, The Dynaloy 190 datasheet indicates an immersion time of 4-8 hours needed, not 2. -----Original Message----- From: Luan Nguyen [mailto:[log in to unmask]] Sent: Tuesday, June 02, 2009 5:06 AM To: [log in to unmask] Subject: [TN] Coating tripping method. Hi Technet, We are having a problem concern to trip coating. Details such as: Material: Humiseal 2A64 Part A Humiseal 2A64 Part B Thinner 64 Dynaloy Dynasolve 190 (GEL 190) Mixer 200 gram Humiseal 2A64 Part A and 200 gram Humiseal 2A64 Part B, stir them , after pour 75 gram Thinner 64 to this mixer. Viscosity: 20 seconds. Method: Using Dynaloy Dynasolve 190 to strip coating on PWA (Immerse PWA into Dynaloy Dynasolve 190 about 2 hours) We can not strip the coating layer by this method. Would you please help us to solve this problem. Thanks and best regards, *************************** Nguyen Hoang Luan QC&Training Supervisor Spartronics VietNam Co, Ltd.
