First choice, due to excellent adhesive properties.
COLATAN………..……...….............................…..based on vegetable Quebracho Tannin
Colatan GT10……...….…..…….........…..…..Reduction of formaldehyde emission
    GT10 is a natural polymer, its curing does not require additional formaldehyde; in contrast, it cures by blocking the formaldehyde content of synthetic resins. It has been specifically developed as a replacement for urea and/or urea - melamine - phenol – formaldehyde - resin - based - adhesives. Thus, Colatán GT10 can be used as formaldehyde scavenger in ureic resins with free formaldehyde, replacing 20% of resin by 20% of Colatán solution at 50% solids, with no variation in its adhesives and cohesive characteristics. This reducing formol emissions to level under ISO E1 scope.
