Hardeners speed up and control the polymerization of amino resins .
All our hardeners are latent and chlorine free. They reduce the pressing time needed for the curing of resins and guarantee a good pot life to the impregnation bath. dosage is recommended according to the required reactivity in the resin bath.
Penta HRD- 9331 is a latent hardener for MF resin . Developed to be active only at high temperature it avoids the pre-reticulation of the resin during the impregnation that might cause surface problems like heat lines and lack of homogeneity and gloss. It also optimizes the resin flow especially in the production of embossed laminates. The product, under the press at high temperatures, starts its activity and guarantees optimal catalysis of the impregnated paper with no need to change the normal pressing cycle.
