Hot Polymerized SBR

Lion is the leading provider of crosslinked and non-crosslinked hot polymerized emulsion styrene-butadiene rubber (eSBR) polymers for the adhesives and sealant industry.

Our non-crosslinked polymers are recommended for a variety of adhesive and sealant applications. When incorporated in a solvent along with appropriate tackifier, these polymers produce tacky cements for bonding, coating and sealing applications, including tapes and labels.

Our terpolymers partially crosslinked with divinylbenzene produce adhesives and sealants with a non-stringy, buttery consistency. They are particularly useful for caulking compounds, mastics, and sprayable adhesives. Adhesives produced with polymers such as 1009C, 1009AFC and 4503C provide a clean breakaway when caulked or troweled. When used in expandable sealants, these polymers offer controlled expansion. These polymers produce extruded profiles with excellent dimensions (low die swell).
