Abstract
A fully pigmentable, non-asphalt based, sealant composition for sealing cracks and joints in roads, streets, highways, sidewalks, pavements, and other concrete and asphalt surfaces. The pigmentable sealant is produced by (i) forming a non-asphalt base blend which contains a high concentration of a rosin ester material, (ii) neutralizing the color of the base blend using one or more color neutralizing materials, (iii) pigmenting the color-neutralized base blend to a desired final color, and (iv) adding one or more polymers to the pigmented blend to provide enhanced mechanical properties.
Claims20
A method of producing a pigmented sealant product composition for cracks and joints in pavements and other substrates, the method comprising the steps of:
- a) forming a sealant base blend having substantially no asphalt therein, the sealant base blend comprising (i) a rosin ester material, (ii) processing oil, and (iii) one or more plasticizers, the sealant base blend being formed at a temperature, and with agitation, stirring, and/or mixing, to melt the rosin ester material and incorporate the rosin ester material into the processing oil;
- b) at least partially neutralizing a non-white shade or color of the sealant base blend, to produce an at least partially color-neutralized base blend, by adding one or more color-neutralizing materials to the sealant base blend, the one or more color-neutralizing materials comprising titanium dioxide;
- c) pigmenting the at least partially color-neutralized base blend, to form a pigmented base blend, by adding one or more pigment materials to the at least partially color-neutralized base blend;
- and
- d) adding one or more elastomeric polymer materials to the pigmented base blend to form the pigmented sealant product composition, the rosin ester material being present in the sealant base blend formed in step (a) in an amount which is greater than 40% by weight based upon a total weight of the pigmented sealant product composition, wherein the total weight of the pigmented sealant product composition comprises a total combined weight of the rosin ester material, the processing oil, the one or more plasticizers, the one or more color-neutralizing materials, the one or more pigment materials, and the one or more elastomeric polymer materials.
