Reducing Agents

Since 1926, Brügge­mann has success­fully manu­fac­tured and sold Brug­golite® sulfur based redu­cing agents. Based on Sodium Form­al­de­hyde Sulfoxylate, the very first indus­trial chem­ical from Brügge­mann, our devel­op­ment expertise has expanded the applic­a­tion areas where these products enable our customers to improve their mater­ials.

Brügge­mann is the first company to offer a sulfur-based form­al­de­hyde free redu­cing agent, Brug­golite® FF6 M.  Our unique R&D activ­ities continue to develop new, envir­on­ment­ally friendly grades of redu­cing agents that provide addi­tional bene­fits.  In addi­tion to Brug­golite® grades in solid form, we also produce redu­cing agents in stable liquid form for customers that want to avoid solid hand­ling.             

Our redu­cing agents are supplied glob­ally to improve water­borne emul­sion poly­mers.  New regu­latory demands for VOC/Form­al­de­hyde reduc­tion in coat­ings and adhes­ives are achiev­able with our advanced redu­cing agents, enabling water­borne poly­mers to replace solvent based mater­ials in many areas. Other typical indus­trial uses include textile, paper, and mineral bleaching.

Advanced Form­al­de­hyde Free Redu­cing Agents

Form­al­de­hyde free redu­cing agents from Brügge­mann enable solu­tions for the latest tech­nical chal­lenges of envir­on­mental aware­ness, rising quality demands, and improved applic­a­tion perform­ance.  Our products and tech­niques enable emul­sion polymer produ­cers to improve effi­ciency with more sustain­able raw mater­ials. All offer the following attrib­utes:

  • Form­al­de­hyde and VOC free
  • Increased react­ivity – better perform­ance at lower dosage and time
  • Low to zero residual free monomer level
  • Non yellowing
  • FDA Direct Food Contact approval
  • Dust free micro gran­ules
