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.
Formuiating guidelines
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.
