Abstract
A composition for use as a binder system for road marking formulations and methods for making thereof is disclosed. The binder system is provided as pellets. The method provides for making the pelletized binder system, and mixing the pelletized binder system with fillers and other components, heating the mixed ingredients forming into a molten mixture for applying on a road surface. The pelletized binder system comprises at least a resin and an elastomer in one embodiment; at least a resin and a plasticizer in a second embodiment; and at least a resin, an elastomer, and a plasticizer in a third embodiment.
Claims20
A pelletized binder composition for use in road marking applications, comprising based on total weight of the binder composition:
- a resin selected from hydrocarbon resins, alkyd resins, and combinations thereof in an amount of 20 to 96 wt. %;
- an elastomer in an amount of 1 to 40 wt. %;
- an optional component selected from:
- a plasticizer selected from vegetable oils, mineral oils, process oils, phthalates and mixtures, in an amount up to 10 wt. %;
- a wax in an amount up to 10 wt. %;
- a pigment in an amount of up to 15 wt. %;
- and
- a filler in an amount of up to 50wt. %;
- wherein the resin, the elastomer, and the optional component are combined together as pellets of a homogeneous composition prior to being combined with other components forming the pelletized binder composition for use in road marking compositions.
A method for forming a road marking composition comprises:
- providing pellets of a homogeneous composition comprising at least a resin selected from hydrocarbon resins, alkyd resins, and combinations thereof in an amount of 20 to 96 wt. %;
- an elastomer in an amount of 1 to 40 wt. %, and optionally a plasticizer selected from vegetable oils, process oils, phthalates and mixtures, in an amount of 0.1 to 10 wt. %;
- and
- mixing the pellets with a composition comprising waxes, pigments, and fillers to form the road marking composition.
