2) Application:trifunctional aziridine crosslinker
In water based parquet lacquers to improve water ,alcohol,detergent Chemical and abrasion resistance
In water based industrial wood-,plastic-and metal coatings to increase water ,alcohol and block resistance
In vinyl coatings to reduce plasticizer migration and improve stain resistance
In water based concrete sealers to improve abrasion
Resistance
Generally,to improve adhesion of water based systems to non-polar substrates
In solvent based polymers to increase resistance properties
In water based printing inks to improve water and detergent resistance 
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
Available 4*5Kgs plastic pails per Carton ,25Kgs plastic drums ,200Kgs plastic drums and 1000Kgs IBC drum. Store in a cool, dry, dark place. If stored under conditions of excessive heat for extended periods the material may discolour, deteriorate and gel.
