Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...
The "drying", hardening, or, more properly, curing of oils is the result of autoxidation, the addition of oxygen to an organic compound, and the subsequent crosslinking.. This process begins with an oxygen molecule (O 2) in the air inserted into carbon-hydrogen (C-H) bonds adjacent to one of the double bonds within the unsaturated fatty
There are limitations in the select coat process, such as capillary effects around low-profile connectors that absorb the coating accidentally. The process quality of dip or dam-and-fill coating and non-atomized spray technology can be improved by applying and then releasing a vacuum while the assembly is submerged in the liquid resin.
Heat-sensitive carbon fiber tubes coated with a UV curable powder coating. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
There is solvent-based and water-based. Solvent-based acrylic paints are soluble in mineral spirits, and water-based acrylic paints are water-soluble. Acrylic paint differs from oil paint in both its quick drying time, and how the paint dries. Acrylic paint dries in as little as thirty minutes, and dries by the evaporation of the solvent or ...
The solvent also modifies the curing rate and viscosity of the paint in its liquid state. There are two types of paint: solvent-borne and water-borne paints. Solvent-borne paints use organic solvents as the primary vehicle carrying the solid components in a paint formulation, whereas water-borne paints use water as the continuous medium.

Coatings were prepared by moisture curing of IPDI capped hydroxyl terminated polybutadiene/clay dispersions in a relative humidity (RH) of 50% at 25 °C. Moisture cured polyurethane–urea coatings have been made by reacting 1,2,3-triazole rich polyether polyols with HMDI at NCO/OH eq. ratio of 1.2 to obtain isocyanate-terminated polyurethane ...
