Plast Retard PE is a highly efficient setting retarder by increasing the workability time proportionately to the dosage.
Plast Retard PE acts as retarder in the gypsum-water mixture slowing down the growth of the hydrate crystals.
The Plast Retard PE activity is characterized by the correlation between setting time and dosage and gives excellent performance at both high and low dosage rates.Generally Plast Retard PE is used alone in gypsum formulations but it is totally compatible for use in formulations containing citric and tartaric acidin order to have a delayed hardening and a suitable consistence/time diagram.
Plast Retard PE acts also in gypsum formulations containing lime, traditionally added as thickner and anti-mould agent.
