Crosslinker SaC-100 is a 100% active, polyfunctional aziridine liquid crosslinker. Additional of 1-3% to water based acrylic emulsions or urethane dispersion produces a marked improvement in water, chemical, abrasion and humidity resistance and enhances adhesion to specific substrates. Crosslinker SaC-100 is room temperature reactive and therefore can be used under air and forced drying conditions.

Recommendations for end-use
- In water based parquet lacquers to improve water, alcohol, ***ergent, 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 ***ergent resistance.
Formulating guidelines
- 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 |
