Retroreflective articles comprising a non-thermoplastic hydrocarbon elastomer adhesive layer for life saving devices at sea

摘要

Retroreflective articles for life saving devices at sea are described comprising a layer of a pressure-sensitive adhesive made using a solvent-free hot melt process which employs as starting material a tackified non-thermoplastic hydrocarbon elastomer. The process employs a continuous compounding device that has a sequence of alternating conveying and processing zones.
