An improved process of coating tacky or soft polymer pellets to maintain a free-flowing property, uses a liquid binder, in conjunction with an anti-tack or partitioning powder such as talc to prevent aggregation during storage. The binder is a non-volatile material such as an oil or plasticizer including triglycerides, mono-/di-glycerides, acetylated mono-/di-glycerides, fatty acids, epoxidized triglycerides, phthalates, benzoates, sebacates, lactates, citrates, mineral oils etc. Applications of this process include chewing gum bases, hot-melt adhesives, sealants, rubber masterbatches, powdered rubber, and other soft and tacky polymer materials. |
