摘要： An asphaltic sealant composition and method which use (a) the incorporation of one or more pigment and/or UV absorbing materials, (b) a low shear production method, and (c) the addition of an epoxidized ester of a vegetable oil or a plasticizer, effective for increasing the degree of dispersion of the pigment material in the sealant composition, to provide improve resistance to UV radiation.

摘要： 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.

摘要： A non-asphaltic sealant composition, and methods of producing and using the sealant composition, wherein the non-asphaltic sealant composition includes a sufficient amount of one or more polar, non-asphaltic base resins having functional groups for hydrogen bonding to provide high adhesion for sealing cracks and joints in polar concrete pavements and other polar substrates.

摘要： A method for testing and selecting a crack and joint sealant for superior performance in both hot and cold climates, as well as for superior ability to relax stress during crack or joint opening and closing, wherein the rheology of the crack and joint sealant composition is evaluated by (i) testing the sealant composition using dynamic shear testing in parallel plate mode at a plurality of frequencies for a plurality of temperatures and (ii) performing flexural testing in a 3-point bending mode at different temperatures, and using the results of these tests to produce a Black Space diagram and Master Curve for the sealant, and perform further analyses.

摘要： Hot-applied asphaltic and non-asphaltic sealant compositions and methods having or using defined effective polymer concentration (EPC) values of at least 7.0 are provided which (a) provide improved softening points and improved resilience without the use of any inorganic filler materials, while at the same time maintaining or increasing the ductilities of the compositions, or (b) enable the use of one or more inorganic filler materials to provide improved softening points and improved resilience while maintaining desirable viscosity levels and at least significantly limiting any losses in ductility or increasing the ductilities of the compositions.

摘要： A 100% solids composition and method for priming or sealing a concrete surface wherein the 100% solids composition is formed of a tree rosin ester resin and a vegetable oil or vegetable oil-derived plasticizer, which are renewable or largely renewable, and wherein the 100% solids composition provides strong adhesion, can be applied by brushing or spraying at a temperature of less than 400° F. without adding a solvent or water thereto, produces substantially no VOCs, requires no time for curing or evaporation, and is ready for traffic or other normal use after cooling.
