Terra Alba No. 1

The dihydrate form of calcium sulfate used in low temperature thermoset plastic and specialty cement applications.

Overview

The dihydrate form of calcium sulfate used in low temperature thermoset plastic and specialty cement applications.
Often used as a flame-retarding filler when processed at room temperature.

Terra Alba No. 1 is a dihydrate form of calcium sulfate produced by fine grinding and air-separating high-purity, white gypsum containing 20% water of crystallization. It releases combined water as it is heated above 50°C, releasing 75% of water as temperatures reach 180°C (only when temperatures exceed 400°C is water totally removed).

MAIN FEATURES
Terra Alba No. 1:
Can be used as a flame-retarding filler when processed at room temperature
Contributes to desired expansion, green strength and controlled set in specialty cement applications
Is a relatively soft material (2-3 Mohs scale hardness) contributing to minimal wear on equipment.
