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. FORMUlATING GUIDELINES Crosslinker XC-100 is a tri-functional material that crosslinks polymers with reactive carboxyl functionalily; Typical addition levels of XC-100 necessary to fully crosslink acrylic emulsions and urethane dispersions are 2% and 3% respectively; Crosslinker XC-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 XC-100 and water; In water borne formulations, XC-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 XC-100 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-100 it is desireable to prevent inhalation of vapours by proper ventilation or respirator use. PACKAGE & STORAGE Available 4*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.
