Chất tăng bền ướt KYMENE® 705

PRODUCT DESCRIPTION AND USE

Kymene® 705 is a water-soluble, polyamide- epichlorohydrin, thermosetting crosslinking  polymer that is reactive with amine, carboxyl, hydroxyl, and thiol functionality. Polymers having carboxyl groups are generally the most reactive and will react even at room temperature. The rate and degree of crosslinking is influenced by concentration, pH, and temperature. Crosslinking will occur from pH 4-9 with optimum results obtained under mild alkaline conditions. Optimum cure occurs from 40 to 65˚C.

 

BENEFITS

  • Water-based formulation
  • No formaldehyde intentionally added
  • Reactive over a wide pH range
  • Low viscosity, low odor liquid

 

PRODUCT APPLICATION

When solutions of Kymene resin are mixed with polymers containing reactive carboxyl groups- for example, sodium carboxymethylcellulose or sodium polyacrylate-solution viscosity may rise rapidly. This  can be controlled by adjusting pH of the polymer solution within the range of 8 to 9 before adding the solution of Kymene resin. Good agitation must be maintained during mixing to ensure uniformity and viscosity control.

 

The pot-life of various mixtures have not been completely investigated. If it is necessary in commercial practive to apply the water-soluble polymer at elevated temperatures, pot life of the application bath containing Kymene 705 should be determined under the conditions of actual practice. The variables listed previously that influence the rate and degree of insolubilization will likewise influence pot life.

Kymene 705 is to be used in accordance with control procedures Hercules establishes for a specific application.
