2) Application  

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   

Crosslinker C-100 is a tri-functional material that crosslinks polymers with reactive carboxyl fun- ctionality

Typical addition levels of it necessary to fully Crosslink acrylic emulsions and urethane dispersions are 2% and 3% respectively 

Polyaziridine should be added to lacquers,paints or inks prior to use and due to its excellent water miscibility it can be stirred in by using a 1:1 premix of polyaziridine and water.

In water borne formulations ,polyaziridine will slowly hydrolyse and blends should therefore be used with- in 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 polyaziridine must be used within 5 days because they tend to thicken and may be gel within 2 weeks
