Guest Post by Jeremy Pasatta, Advanced Polymer Coatings All the epoxy curing agents in the last set of blog posts (amines, mercaptans and anhydrides) required mixing of the epoxy with the curing agent just prior to curing and are therefore considered two component formulations. Good flexibility and adhesion, good substrate wetting, good temperature resistance. Low viscosity, good impregnation, high filler loadings. m Long pot-life, flexibility. Long pot-life. Excellent waterspot resistance. Therefore, the mechanical properties of diglycidyl ether of bisphenol a (DGEBA) cured with l-arginine were investigated to determine whether the bio-based thermoset possesses the required mechanical properties for . Usually, the press cure is carried out at 149 for 30 minutes, and post cure is for 24 hours at 204. Use this grade where the lowest lead and highest SA is required and standard grade 112 USP is not suitable in the application. Alternative to Mannich bases. Adhesion on humid concrete. Accelerator for epoxy/polyamine and epoxy/polyamide systems. Curing is the process or operation which controls the loss of moisture from concrete after it has been placed in position, or in the manufacture of concrete products, thereby providing time for the hydration of the cement to occur. An intermediate case involves a mixture of resin and additives that requires external stimulus (light, heat, radiation) to induce curing.
