Appearance: colorless to light yellow transparent liquid 
Viscosity (25 °C): 30 ~ 100 cp 
Density (20 °C): 1.09 g / ml 
Solubility: completely dissolved in water, alcohol, ketone, ester and other solvents

Usage

Addition method : HD-300-3 can be directly added to the system under vigorous stirring. For water-based acrylic emulsion and aqueous polyurethane dispersion, HD-300-3: water = 1: 1 ratio can also be added;

Adding amount : Usually 1 to 3% of the solid content of acrylic emulsion or polyurethane dispersion. In special cases, it can be added up to 5%. The specific dosage can be determined by customers according to the actual situation.

System pH : The pH of the emulsion and dispersion system is between 8.0 and 10, and HD-300-3 is the best. It should not be used in acidic medium.

Applicable period: HD-300-3 is a long-acting aziridine cross-linking agent. It can be stored in the system at room temperature (25 °C). The storage period is generally long, up to several days or even months, due to differences in customer Resin system. The specific application period customers need to test themselves.

Processing temperature: HD-300-3 is a medium-low temperature curing cross-linking agent, and the treatment temperature is between 60-80 °C to obtain better results.
