| Description: | - Crosslinker SaC-100 is a tri-functional material that crosslinks polymers with reactive carboxyl functionality (equivalent weight is approx.166). - For many applications 0.6 equivalents of SaC-100 per carboxyl equivalent are sufficient to achieve optimum improvement in film properties. - However some systems may require the full stoichiometric equivalent of crosslinker. - Typical addition levels of SaC-100 necessary to fully crosslink acrylic emulsions and urethane dispersions are 2% and 3%respectively(calculated on wet products). - Crosslinker SaC-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 SaC-100 and water. - In water bome formulations, SaC-100 will slowly hydrolyse and blends should therefore be used within 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 SaC-100 must be used within 5 days because they tend to thicken and may gel within 2 weeks. | |
