BorreGYP: Performance in Gypsum Board

Demonstrations at our laboratory show the performance of BorreGYP in gypsum board. We used a gypsum slurry commonly used in gypsum board manufacturing for this work.

Using BorreGYP as a water reducer in gypsum can influence all parameters: initial flow (see figure below), workability, setting time, compressive strength development and improved adhesion to paper. The effect depends on the dosage. A typical range is 0.1 to 0.5% solids by weight of gypsum (sbwg).

Key takeaways:

• Cost efficient dispersing effect 
• Good adhesion to paper
