Abstract:
The present disclosure related to a method of producing a color stable, light colored lignin. The method includes: reacting a lignin composition with a hypochlorite composition having about 5% to about 70% available chlorine; and reacting the hypochlorite treated lignin with hydrogen peroxide at a concentration of about 5% to about 50% to produce the light colored lignin, wherein the lignin composition includes at least one of sulfonated lignin, lignosulfonate, or both.
Abstract:
The present description relates to an adhesive asphalt or tack coat composition, and method of use. In particular, the tack coat compositions comprise an asphalt binder material, a resin, an emulsifier, and a polymer, wherein the tack coat is non-adhesive at ambient temperatures and adhesive when heat is applied.
Abstract:
Presently described are methods for performing rosin purification. The methods described herein utilize a unique solvent precipitation process that surprisingly and unexpectedly reduces the color of rosin and the sulfur and unsaponifiable contents in the rosin. The described methods are also applicable to rosin derivatives such as rosin esters and amides. Utilizing this purified rosin as raw material, rosin derivatives with much improved characteristics (color, softening point and sulfur content) can be made that would otherwise be difficult to make.
Abstract:
The present description provides esterified fatty acid and/or tall oil compositions and their use as alternative plasticizers in adhesives formulations. These esters demonstrate similar or improved performance over adhesives industry standard plasticizers. The description also provides methods of manufacturing and using the same, for example, to improve or modify the performance of adhesive materials, such as, hot melt pressure sensitive adhesives and hygienic adhesives.
Abstract:
The present description relates to method of initiating the curing of carboxylic acid-treated material compositions to enable an initial lowering of the viscosity and stiffness of the material for low temperature wetting and coating of solid surfaces, for paving, for waterproofing, for roofing, and for underlayment applications. The present description relates to ecologically sound, non-toxic technology that enables a practitioner to improve the low-temperature cracking properties of a material or material composition while also inducing a rapid increase in the high- temperature stiffness and viscosity of the material or material composition, and to rapid cure and strength development of finished product composition for application in paving, roofing, adhesive interlayer bonding, roll finishing, blow-molding, water-proofing, and underlayment.
Abstract:
Disclosed herein are lubricating compositions and methods of the same, including for, e.g., use in metalworking operations. The lubricating compositions include a partial or half-ester of a compound derived from the Diels-Alder reaction of a conjugated fatty acid and an acid precursor dienophile.
Abstract:
Presently described are curable compounds and curable compositions. Thermosets including the curable compounds and curable compositions described herein are derived from bio-based components and have improved mechanical properties. The described compositions can also be applicable to rosin derivatives and fatty acid derivatives.
Abstract:
Carboxylic acid adducted rosin polyol ester with fatty acid functionality compositions, methods of making the same, use of the same in adhesives, and methods or preparing the same are disclosed herein. The method of producing the carboxylic acid adducted rosin polyol ester with fatty acid functionality includes the steps of: adding and mixing a carboxylic acid (e.g., an α,β-unsaturated carboxylic acid) to a molten rosin to produce a carboxylic acid adducted rosin; esterifying the carboxylic acid adducted rosin by reaction with a polyol to produce a carboxylic acid adducted rosin polyol ester; and reacting the carboxylic acid adducted rosin polyol ester with a fatty acid material to produce the carboxylic acid adducted rosin polyol ester with fatty acid functionality.
