FGR-95

Hydrocal FGR-95 – Alpha Gypsum

FGR-95 is a long set time alpha plaster (gypsum) design for use with fiberglass reinforcement. It allows the manufacture of large and intricate architectural elements for indoor applications at relatively low cost and ease of processing. This system is also great for case moulds or mother moulds when FMG (Forton Modified Gypsum) is not required.

Forton MG
When FGR-95 is used in conjunction with VF-812 acrylic polymer, Forton MG (Forton Modified Gypsum) is created. FMG is based on the VF-812 water based polymer emulsion (50% solids) and greatly enhances the physical properties of alpha gypsum products. The Forton™ MG system is easy to use and can be cast solid, rotationally cast, layed up by hand with glass fiber or sprayed. Fully cured pieces can be painted, sanded, machined and polished. FMG is used to make lightweight pieces that are very strong and water-resistant. Applications include making architectural elements, reproducing sculpture and special effects. Metal Powders and Pigments may be added, please check data sheet for recommended ratio and details. We recommend that this system is mixed/sheared mechanically and not by hand for optimum results. This system may be used in different ratios, but the most common is 100:50 FGR-95 to VF812. This means 1 x 22kg bag to 1 x 10kg polymer.

Mixtures
33 parts water to 100 parts powder
5-6% by weight Type E chopped to 3/4 in. (19 mm) length

Main Features
Hydrocal® FGR 95 is a high-strength gypsum cements specially formulated for use with glass fiber for fabricating glass-reinforced architectural details. This product is an alpha hemihydrate gypsum-based materials, with low water requirements that result in high-strength, high-density pieces. Allows for the economical duplication of architectural details formerly produced from plaster, wood, concrete or stone.

Hydrocal® FGR 95:
Produces lightweight, thin-cast, architectural details
Superior fabrication flexibility – from simple cornices to ornate capitals and medallions
Effectively duplicates pieces formerly made of plaster, wood, concrete and stone
Exceptionally quick set – 50-70 minutes with manual application
Accepts most coatings and finishes.
