It has ring structure, contains part of double bond and has high cohesion.Molecular structure does not contain polar or functional groups, no chemical activity.Good acid and alkali resistance, chemical resistance and water resistance.Poor adhesion performance, brittleness, aging resistance is not good, should not be used alone.It has good compatibility with phenolic resin, ancient Malone resin, terpene resin, SBR and SIS, but poor compatibility with non-polar polymers due to its high polarity.Combustible.Non-toxic.Mainly used as SBS universal adhesive, SBS spray adhesive, film adhesive, pressure-sensitive adhesive, hot-melt pressure-sensitive adhesive and other adhesives viscosity Resina.mabalin met nga usaren para iti neoprene adhesive tapno mapabassit ti gastos, ti maitutop a dosis ket saan a mangkissay iti pigket a pigsa ti neoprene adhesive..
