SP-560

SP-560 is a high-performance tackifier resin designed to strengthen adhesive systems by improving tack, wetting, peel resistance, and heat stability.
SP-560 is widely used in hot-melt adhesives, pressure-sensitive adhesives, contact cements, and rubber-based formulations where durable bonding is required.
SP-560's compatibility with oils, waxes, and rubbers makes SP-560 a versatile resin for enhancing both processing behavior and final adhesive performance.

SP-560 is a thermoplastic, oil soluble, terpene phenolic resin.
SP-560 is mainly used in adhesives as either the base resin or as a modifying resin in the formulation of polychloroprene cements.
SP-560 can also be used in hot melt or solution adhesives made from other elastomers where the combination of high tack and high heat performance is desired. 

SP-560 is a thermoplastic rosin-phenolic resin.
SP-560 is mainly used as a bio-based tackifier in adhesive formulations for hot melts, polychloroprene contact cements and other solution adhesives, pressure sensitive adhesives, etc.

SP-560 imparts to adhesives a possibility to bond successfully over a wide variety of substrates (polar and non-polar).
SP-560 improves the adhesiveness through improved surface wetting, high tackiness, high heat performance, and peel resistance.

SP-560 can also be used in the hot-melt or solution adhesives made from other elastomers where the combination of high tack and high heat performance is desired.
SP-560 in combination with polychloroprene used to formulate polychloroprene cement and display good strength and tack retention properties.

In order to improve high-temperature performance, SP-560 may be blended in any proportion with heat reactive resins.
The heat resistance of the adhesive formulation increases with the percentage of heat-reactive resin, but this will be gained at the expense of decreasing open time.
SP-560 is compatible with a variety of drying oils, waxes and synthetic rubbers.

SP-560 is a thermoplastic, oil-soluble rosin-phenolic / terpene phenolic resin used mainly as a tackifier in adhesive and rubber formulations.
SP-560 is designed to increase tack retention, surface wetting, peel resistance, and high-temperature adhesive performance in systems such as hot-melt adhesives, polychloroprene contact cements, pressure-sensitive adhesives, natural rubber adhesives, and SBR adhesives.
SP-560 can also be used as a processing aid in rubber compounding because it is compatible with many oils, waxes, and rubbers.

Applications of SP-560:
SP-560 is mainly used as a tackifier resin in adhesive and rubber formulations.
SP-560 is suitable for hot-melt adhesives, polychloroprene contact cements, solvent-based solution adhesives, pressure-sensitive adhesives, natural rubber adhesives, and SBR adhesive systems.

SP-560 helps improve tack retention, surface wetting, peel resistance, heat performance, and overall bond strength.
SP-560 can also be used as a modifying resin or processing aid in rubber compounding because it is compatible with many oils, waxes, and rubbers.

SP-560 lowers the viscosity, increases open time, improves the surface wettability on different substrates, provides strong green tack in polychloroprene adhesives.
SP-560 is suitable for color sensitive applications.

When used in hot melts SP-560 will provide very stable operating viscosity even at high temperatures, and due to narrow molecular range and high softening point it will provide fast adhesive setting with the high level of bond strength.
SP-560 is also successfully used as a tackifier and processing aid in rubber compounding.

SP-560 is compatible with a wide variety of oils, waxes, and rubbers.
Due to high bio-based content and its non-hazardous nature, SP-560 is especially suitable for rubber articles for indoor use and any other rubber goods with the increased concern over EHS impact and product sustainability
