U.S. Gypsum's
Industrial Plasters Meet a Variety of Ceramics, 3-D Casting/Statuary, Dental
and Specialty Uses
Industrial plasters
from the Industrial Products Division of United States Gypsum Company offer
low-cost solutions for a wide range of industrial product applications,
processes and development opportunities.
The plasters provide a
controllable setting performance few other materials can offer. By adding
accelerators or retarders setting times can be lengthened or shortened. Setting
times can also be reproduced batch to batch.
The plasters also offer
controllable expansion -- ranging from 0.0005 to 0.0156 inch per inch (or 3/16
inch per foot). Plaster formulations come closer to zero expansion than nearly
any other cementitious material.
U.S. Gypsum Company offers a range of
industrial plasters which meet the specific production requirements for a
variety of industries.
Ceramic Plasters
For ceramic
production, U.S. Gypsum Company offers four products:
Pottery
Plaster – A general purpose product recommended for most slip casting
applications in the ceramic industry.
No. 1 Pottery Plaster
– Formulated to provide stronger, longer-lasting ceramic slip molds. It's
the industry standard.
PURITAN® Pottery Plaster
– A slightly denser, longer-wearing mold material that is recommended for
jiggering applications.
DURAMOLD™ Pottery Plaster –
Formulated to provide a longer-lasting, more durable gravity slip casting mold.
It is used at a lower consistency than conventional pottery
plasters.
3-D Casting Statuary
Plasters
Moulding Plaster
– A good general purpose plaster
where expansion, control, hardness and strength are not of major importance.
(The product is referred to as "casting plaster" on the West
Coast.)
Industrial Gauging Plaster
– A coarser-grind product
than Moulding Plaster, resulting in lower water demand for
mixing.
White Art Plaster
– Similar in working properties to
Moulding Plaster. It features a surface hardening agent that reduces paint
absorption.
No. 1 Casting Plaster
– Similar to White Art
Plaster, except it is mixed at a lower-use consistency to increase strength and
chip resistance and to further reduce paint absorption.
TUF CAL™
Plaster – A unique polymer-modified, high early-strength fibered
plaster. It provides higher green strength and greater chip and impact
resistance than White Art Plaster, No. 1 Casting Plaster or
HYDROCAL® White Gypsum Cement. It is ideal for hollow cast
products.
Dental
Plasters
Regular Dental Plaster – A normal set dental
plaster recommended for general purpose applications. Similar to Moulding
Plaster.
Laboratory Dental Plaster – The same properties as
Regular Dental Plaster, except for a faster set time (6 to 9
minutes).
Impression Dental Plaster – Designed for mouth
impression work, it has the fastest setting time of all dental plasters (3 1/2
to 5 minutes).
Specialty Plasters
AIRTROL®
GeoBinder – Formulated for use in hydroseeding equipment to control
erosion while providing protective cover to stimulate plant growth. It also can
be sprayed over coat refuse piles to smother spontaneous combustion fires.
Other uses includes dust control.
Metal Casting Plaster – A
combination of industrial plaster, sand and refractory materials for casting
nonferrous matchplates.
