AVCO-CID HTA 200

AVCO-CID HTA 200

Rainbow is Avco preferable colour!

An acid donor that creates acidity when solutions of the product are heated up. The pH of 0.1% AVCO-CID HTA 200 is 6.5 - 7.5, and when heated to the boil the pH decreases to 4.5 - 5.5. The rate of dissociation is slow in cold solution sand increases while heating up.

Properties & uses:

  • An acid donor which evenly and slowly hydrolizes in hot aqueous solution to produce an organic acid
  • During the hydrolizing process the organic acid produced is lowering the pH of the solution down to 4.5 - 5.5 according to the concentration in the liquor
  • The rate of the dissociation is slow in cold solutions and increases when the temperature is raised
  • Useful for dyeing acid and metal complex dyes. As the exhaution rate of acid dyes is pH dependent, the slow lowering of the pH in a dyeing solution containing the product, ensures more level dyeing, due to slower exhaution rate of the dyestuffs onto the fibres
  • Recommended for even dying of polyamide, wool and blends of these fibres
  • When using the product, the initial temperature of the dyeing can be increased, and the rate of heating up may be faster, thus reducing dyeing time
  • Does not influence any of the fastness properties of the dyed fibres

Ionicity:

  • Nonionic
