    Product Description

    Pro Stone 21 is a formulated hemihydrate plaster (CaSO4, ½ H2O) produced from naturally occurring gypsum mineral. It exists in white, pastel, yellow or pastel peach color. Used in the dental industry, Pro-Stone 21 is an extra-hard stone plaster with very lowexpansion for very precise fixed prosthetic work

    For consistent result, attention must be given to the correct proportioning and mixing of the plaster and water. Add the weighed quantity of plaster slowly into the measured volume of water and allow to soak for 30 second. Stir vigorously by hand with a spatula for 30 to 60 seconds to obtain a uniform mix. If mechanical mixing is used with or without vacuum, the mixing time can be reduced. To obtain very time details and to exclude air bubbles, the plaster should be vibrated into the impression. The fluidity of the mix can be increased by increasing the proportion of water, however this will result in reduced strength and hardness.

    Do not mix fresh plaster with that which has been mixed for some time previously.

    When stored under dry conditions, this product will have a shelf life of twenty-four months.

    Absorption of moisture can result in changes to physical properties including a reduction in the set strength of plasters and also lengthening of setting time. To help protect the products during use, open or part used containers should be carefully closed.
