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.
