Aqueous cross-linking agent DT-100
DT-100 crosslinking agent is a 100% active polyfunctional aziridine crosslinking agent. Press 1-3% added water-based acrylic emulsion or polyurethane dispersion of its water resistance, chemical resistance, high temperature and in particular Adhesion on substrates have significantly improved cross-linking agent DT-100 for the cross-linking reaction at room temperature, but there is warm for spraying or baking process better.

Recommends that the end-use:
1, in an aqueous hard wood floor paint can improve its water resistance, alcohol, detergent-resistant, resistant to chemicals and abrasion resistance.
2, in aqueous industrial paint can improve its water resistance, alcohol, anti-adhesive.
3, in the vinyl coating can reduce plasticizer migration resistance, improved stain resistance.
4, to improve its wear resistance in an aqueous cement sealant.
5, aqueous systems can generally improve adhesion on non-porous substrates.
6, to improve the solvent-based polymer patience.
7, to improve water-based ink and water-resistant detergent properties.
8, improve water-based printing coating water resistance, temperature resistance viscous behavior.
9, improving leather coatings water resistance, washing resistance, chemical resistance and high temperature of the performance.
1, DT-100 is a trifunctional crosslinking agent reaction (equivalent number 166) can react with the polymer carboxyl groups.
In most cases the amount of carboxyl groups reacted well DT-100 for the best improvement in results whenever 0.6 equivalents, but
Some system requirements equivalent crosslinking agents react.
2, under normal circumstances, all of crosslinked acrylic or polyurethane dispersion is a 2% or 3% of the DT-100 (in weight).
3, DT-100 should be in front of varnish, paint and ink to join, due to its excellent miscibility, it can stir by hand using the best join method: First DT-100 with water 1: 1 mix dissolved again added to the system.
4, an aqueous formulation added DT-100 will gradually hydrolysis, the mixture should be used within 3-5 days, but no adverse effects on the polymer emulsion peace hydrolyzate film. Also, adding a certain amount of DT-100 may pay linking reaction is restored.
5, DT-100 can improve the overall performance of solvent-based polymer systems, but must be used up in five days, two weeks due to the viscosity of the system tends to be high and may form a gel.
