PlastRetard® is the most used Retarder “additive” in the gypsum industry worldwide.
PlastRetard® is manufactured and commercialized in powder and in liquid form.
PlastRetard® in powder form is called PlastRetard PE. PlastRetard PE is used to produce all gypsum based formulations for any application (hand plaster, machine plaster, jointing fillers, finishing plaster, etc..).
PlastRetard® L (liquid retarder) is only used for Plasterboard and gypsum blocks production.
In Plasterboard® production PlastRetard® L, besides working as a retarder, acts also as a fluidizer, increasing the fluidity of the stucco. These properties allow to lower the dosage of the fluidizer and/or diminish the water dosage, increasing the productivity of the dryer. As a consequence, this will decrease the production costs of the gypsum board.
The retarding performance of PlastRetard® in the final formulation is correlated with its dosage with a linear function.
PlastRetard® PE, independently by the type of stucco, will optimize your gypsum based formulations, permitting with few test to fine tune the setting time according to the needs of the final users.
