Doublident is a liquid duplicating material based on additional-curing silicones. The two liquids, base and catalyst are mixed in the ratio 1:1, either by hand or in the mixer. Doublident reproduces tiniest details. The impressions made of Doublident are tear-proof and practically do not shrink. Therefore, they can be used several times and are storable for a long time. Doublident corresponds to the ADA Spec. No. 20.
