3) Formulating guidelines:Polyfunctional Aziridine Crosslinking
Crosslinker C-100 is a tri-functional material that crosslinks polymers with reactive carboxyl functionalily; Typical addition levels of C-100 necessary to fully crosslink acrylic emulsions and urethane dispersions are 2% and 3% respectively; Crosslinker C-100 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 C-100 and water; In water borne formulations, C-100 will slowly hydrolyse and blends should therefore be used within 1-2 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 reactivit; Solvent based systems modified by the addition of C-100 must be used within 5 days because they tend to thicken and may gel within 2 weeks.
4)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 C-100 it is desireable to prevent inhalation of vapours by proper ventilation or respirator use.
5)Package and Storage
