3、 Traits

Colorless to brownish yellow transparent liquid.

4、 Operating conditions

project	Standard	Scope
TAD-602	10ml/L	5-20ml/L (prepared with pure water)
Temperature	95 ℃	90-98 ℃
time	40 minutes	Over 35 minutes
PH (25 ℃)	six	5.7-6.3

4、 Usage and Maintenance

1. The pH value is between 5.7 and 6.3, and the sealing ability will not have a significant impact. If it exceeds the range, use ammonia/acetic acid with a mass fraction of 10% to adjust and control the pH value< Br/> In general, replace the tank liquid once every 1-3 weeks. If the addition of TAD-602 cannot achieve good sealing effect due to too many impurities, the tank liquid needs to be replaced< Br/> 3. When used in conjunction with our nickel free pre sealing agent, it can significantly extend the service life of the tank solution, improve the sealing quality, and effectively prevent the fading of various colored dyed parts.
