Use of the Microfoam (DOSHI) Method For Assessing the Effectiveness of Talc in Controlling Stickies, 1998 Recycling Symposium Proceedings

Stickies such as adhesives, hot melts and waxes are of great concern to the pulping and papermaking industry. Many test methods have been developed to measure the impact of stickies and evaluate the effectiveness of stickies control agents. This study utilizes one of the more well-known methods, the Doshi method, to evaluate the effectiveness of talc in detackifying hot melt (poly vinyl acetate (PVA)). With additions of 0.5% talc (on o.d. pulp) the amount of tacky stickies was reduced by 80%. With additions of 2.5% talc, tacky stickies were reduced by 95%.
