General Information

The GLUCOSET product range is a series of products especially designed for the gypsum industry based on gluconates and tartaric acid. GLUCOSET products can substitute the standard set retarder product in gypsum plaster, natural tartaric acid. Natural tartaric acid is prone to strong price fluctuation year on year. Our gluconates-based GLUCOSET retarders offer a reliable performance in retarding for gypsum as well as a significant cost saving compared to tartaric acid.

In order to offer the optimum products for every dry mix gypsum application based on natural and synthetic gypsum, we provide a range of products:

  • GLUCOSET G series is based on micronised (< 60 µm) glucono-delta-lactone, blended with or without tartaric acid
  • GLUCOSET S series is based on specially milled (< 300 µm) sodium gluconate with or without tartaric acid

Jungbunzlauer offers application support to select the right GLUCOSET product at the right concentration based on our experience in extensive lab and application tests.

GLUCOSET by Jungbunzlauer is a new offering to the construction industry which enables our customers a cost saving and well as a price stabilisation option compared to tartaric acid.
