CALCIUMSULFATE BINDER CAB 30 25/1
CALCIUMSULFATE BINDER CAB 30 25/1, is a high-purity (>90% CaSO4) calcium sulfate binder specially formulated for use in industrial flooring applications and screed production. Presented in a grey-white to brown powder form, this product fully meets the requirements of DIN EN 13454 and DIN 18560 standards, ensuring superior mechanical strength and dimensional stability in flooring applications.
Areas of Use and Advantages
This binder yields excellent results in traditional screed pours applied within a mortar temperature range of 5 °C to 25 °C. The product does not contain a superplasticizing agent, thus offering formulators the flexibility to create their own additive packages. When processed correctly, the binder does not exhibit binder-induced horizontal deformation (shrinkage/swelling), allowing it to be used safely and without cracking in large areas.
