Model: XC-113
DESCRIPTION
Crosslinker XC-113 is a 100% active, polyfunctional aziridineliquid crosslinker. Addition of 1-3% to water based acrylic emulsions or urethane dispersions produces a marked improvement in water, chemical, abrasion and humidity resistance and enhances adhesion to specific substrates. Crosslinker XC-113 is room temperature reactive and therefore can be used under air and forced drying conditions.

FORMUlATING GUIDELINES
Crosslinker XC-113 is a tri-functional material that crosslinks polymers with reactive carboxyl functionalily
Typical addition levels of XC-113 necessary to fully crosslink acrylic emulsions and urethane dispersions are 2% and 3% respectively (calculated on wet products)
Crosslinker XC-113 should be added to lacquers, paints or inks prior to use and due to its excellent water miscibility it can be stirred in by hand.
The best method of addition is by using a 1:1 premix of XC-113 and water.
In water borne formulations, XC-113 will slowly hydrolyse and blends should therefore be used within 3-5 days after preparation. The hydrolised products have no adverse effects on the emulsions nor on the dried films, and additional crosslinker may be added to restore reactivity
Solvent based systems modified by the addition of XC-113 must be used within 5 days because they tend to thicken and may gel within 2 weeks

HANDLING
Care must be taken to avoid any contact with the skin and eyes. When used in spray applications, particular care must be taken to avoid oral and/or nasal ingestion by wearing a suitable respirator. When handling XC-113 it is desireable to prevent inhalation of vapours by proper ventilation or respirator use.

PACKAGE & STORAGE
Available 5Kgs plastic pails, and 25Kgs steel drums with inner plastic pails. Store in a cool, dry, dark place. If stored under conditions of excessive heat for extended periods the material may discolour, deteriorate and gel.
