Resin drying
WebWhen compared to classical alkyd resins, binders in air-drying high solids paints have a lower molecular mass and show higher reactivity to autoxidation polymerization. As a result of the high solids content, the thickness of the applied dry film is much higher and as a consequence, the through drying properties are more critical compared to lower solids … WebJun 14, 2024 · Drying of plastic resin can be a key step in the injection molding process, since too much moisture can cause a number of processing problems.
