DF100A is a NPB (n-propyl bromide) based
industrial cleaner. It resembles trichloroethane in physiochemical
properties and cleaning power. It can be used as degreaser
and defluxer in metal processing, precision instruments, electronic
industry, etc.
Characteristics:
1. Low ozone depletion potential (ODP=0.019-0.027) and global
warming potential (GWP).
2. High cleaning power.
3. Fast drying.
4. No flash point.
5. Resistant to hydrolysis, and hydrobromic acid produced
by hydrolysis has weaker corrosiveness compared with hydrochloric
acid.
6. Excellent thermal stability, suitable for vapor cleaning
and recovery.
7. Good safety.
Application:
1. Metal cleaner/degreaser
2. Precision cleaner
3. Defluxer
4. Surface preparation
