Fillers

Plaster contains hemihydrate plaster (plaster of Paris), which is widely used as a construction material, and can take four main forms depending on the degree of hydration of the crystals. These forms have their own distinct characteristics and are used as additives in a wide variety of fields, including food additives, resin fillers, trace moisture removers, and civil engineering.

Uses

Desiccants, absorption inhibitors, function modifiers, fillers, and more

Type-II Anhydrous Plaster: D-700
D-700

D-700 is made by using carefully selected raw ingredients. It exhibits no moisture absorption or hydration hardening, and because it contains no crystallized water, it is used as a filler in heat-resistant engineering plastics. It is used in a wide variety of fields for filler agents of various kinds.

Areas of use
Additive for special cements, filler for (heat-resistant) resins and paints, and more.

Type-II Anhydrous Plaster: D-101A
 D-101A

D-1 is made by firing carefully selected raw ingredients at high temperatures. The transformation to hemihydrate plaster produces extremely good absorbency (instantaneous absorption of moisture from the air). It is used as a desiccant for paints and resins, and as a filler in many different fields.

Areas of use
Trace moisture remover for resins and paints, filler for resins and paints, and more
