Hydrous Calcium Sulfate

$ 161.00 USD
ADLCS.50G

The dihydrate form of calcium sulfate is 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).

Gary, and Mark are great to work with. Very knowledgeable about what they sell and supply, plus installed the equipment very efficiently. I look forward to a partnership for a very long time. Any time I have called on an issue, they get here in a timely manner and get it resolved right away. Donald is one of the best trouble shooters and mechanics i have seen. He really knows his trade.

From the beginning of the remodel to the busy Friday nights, ACS had been a partner that SHINE has relied on. Clean spotless glasses are a necessity for craft beer and ACS has helped us use our old machines to lower our startup cost, and now helping us figure out the best machines to use as our business grows. Great service and even better people.!

Great products and service. Levi checks in all the time to make sure everything is going as it should and is quick to respond when an issue arises in the front or back of house. I love that maintenance is included In being a customer of ACS. Cost is competitive and quality is high.

We lease a dish machine and buy our chemicals through ACS. We have been very happy with the service and Levi is always quick to respond any time we have a question or need assistance.

Our local office in Bozeman is great. They've always been very responsive to any needs we've had on the equipment. Re-ordering chemicals through Bargreen is a different story. We never quite know what's going on with them and when we can expect them to stop in to check on what we need. This would be a 5 star review if ACS didn't rely on Bargreen for supplies distribution.
