COLATAN CF2wp………..……...…....…..Increase of water resistance and speed-machine
COLATAN CF2wp “liquid” is a chemically modified tannin, specifically developed to be used as a starch additive to provide both, high water resistance and “green bond” properties, when applied to corrugated cardboard.
Advantages:
  • Highly soluble in cold water
  • Becomes insoluble only at high pressure and temperature
  • Substantially increase of water resistance
  • Its adhesive features do not alter the adherence capabilities of the final adhesive
  • Works in a wide range of pHs
  • High formaldehyde scavenging capacity
  • Free formaldehyde only 0 up to 0,06 %
  • Substantially increases the speed machine
Properties:
  • COLATAN CF2wp gives high water resistance values under FEFCO No.9 standard, specially in the case of corrugated boxes to environments with high relative humidity (i.e. cold storage rooms)
  • Speed machine can be increased substancially
Dosage:
  • Add between 4 – 5 % CF2wp. This percentage correspond to the total solids present in the secondary tank slurry. Use as any other adhesive. No special facilities or treatments are necessary for Colatan CF2wp.

COLATAN CF 2……..…..…….........…...............................…..Increase of speed machine
COLATAN CF2 “liquid as well as powder” is a chemically modified tannin specifically developed to be used as a starch additive to provide excellent “green bond” and better water resistance properties, when applied to corrugated cardboard.
Advantages:
  • Highly soluble in cold water
  • Becomes insoluble only at high pressure and temperature
  • Increase of speed machine of up to 20%
  • Increases of water resistance
  • Its adhesive features do not alter the adherence capabilities of the final adhesive
  • Does not contain formaldehyde or any of its derivates
  • High formaldehyde scavenging capacity
  • Works in a wide range of pHs
Dosage:
  • Add between 3 – 5 % CF2. This percentage correspond to the total solids present in the secondary tank slurry. Use as any other adhesive. No special facilities or treatments are necessary for Colatan CF2.
