Hydrocal® FGR 95 and Hydrocal® FGR 115

Fast-setting gypsum cement designed for strong, resilient glass-reinforced product fabrication.

Key Documents & Design Files

Overview

Hydrocal® FGR 95 is a fast-setting gypsum cement designed for strong, resilient glass-reinforced product fabrication. Superior fire retardant properties allow for code-compliant installations in a variety of public and private structures. Hydrocal® FGR 115 is a specially formulated, high-strength gypsum cement designed for glass-reinforced product fabrication. Allows for the economical duplication of architectural details formerly produced from plaster, wood, concrete or stone.

Main Features

Hydrocal® FGR 95 and Hydrocal® FGR 115 are high-strength gypsum cements specially formulated for use with glass fiber for fabricating glass-reinforced architectural details. Both are alpha hemihydrate gypsum-based materials, with low water requirements that result in high-strength, high-density pieces.

Hydrocal® FGR 95:
  • Produces lightweight, thin-cast, fire-resistant architectural details
  • Superior fabrication flexibility – from simple cornices to ornate capitals and medallions
  • Effectively duplicates pieces formerly made of plaster, wood, concrete and stone
  • Overcomes building fire code incompatibilities faced by many plastics – at roughly one-third the cost of filled polyesters
  • Exceptionally quick set – 50-70 minutes with manual application
  • Accepts most coatings and finishes.
Hydrocal® FGR 115:
  • Produces lightweight, thin-cast, fire-resistant architectural details
  • Superior fabrication flexibility – adaptable to complex patterns
  • Allows for quick and easy duplication of existing pieces or creation of new products
  • Overcomes building fire code incompatibilities faced by many plastics – at roughly one-third the cost of filled polyesters
  • Sets in 90-120 minutes with manual application
  • Suitable for decorating with a variety of finishes.

q & a

  • How do I determine the proper gypsum cement product based on my end-use application?

    Select products based on the following:

    Strength — USG offers products having compressive strengths ranging from 2,000 to 20,000 psi.

    Flow Characteristics — USG formulates products to be extremely fluid, which is ideal for solid casting and capturing fine detail. USG also produces products with a lot of body for hollow castings and working characteristics needed by the end-user.

    Expansion — Expansion can be helpful for certain applications, or if the need is for close tolerances, we offer products that will perform well. See Literature Numbers IG504 and IG278.

    Set Time — The elapsed time from the moment the plaster and water come into contact until the time when the setting plaster has the ability to support an arbitrarily determined weight.

    Working Time — Do not confuse setting time with working time. Working time refers to changes in the viscosity of the slurry along the way to the set time. Working time is always less time than setting time and varies by product. It is not a published number as customer perception of working time varies based on application.
