Through R&D and close cooperation with our customers, we are continuously improving and expanding our product range to meet today and tomorrow market requirements. Most classical solvents widely used in the coatings, inks, varnishes and adhesives industries are VOCs. Subsequently, ethanolic IL solutions were prepared; MCC was mixed, and the mixtures were left to evaporate . Curing agents or hardeners play an important role in the curing kinetics, gel time, degree of curing, viscosity, curing cycle and the final properties of the cured products. Curing is the process of maintaining satisfactory moisture content and temperature in freshly cast concrete for a definite period of time immediately following placement.

This grade is used in the glass, glazes, ceramics, and frit enamel industry and in applications where high bulk density and free flow is [9], Also in this case the degree of curing goes from zero (no bonds created) to one (no more reactions occur) with a slope that changes in time and has its maximum about at half of the reaction.[9]. A curing agent can be defined as a substance able to participate in the chemical reaction between the oligomer, pre-polymer and polymer, to achieve the polymerization process and provide the final film. It has therefore been used for half a century as an accelerator in the formulation of amine-based hardeners for epoxy resins. Enables to emulsify epoxy resins in water. In QR-Polymers, we believe we can offer waterborne curing agents which address these concerns. The curing methodology depends on the resin and the application.
