Promosolv 70ES is a non-flammable defluxing solvent from Inventec Performance Chemicals. It is a drop-in replacement for trichlorethylene, NPB and other solvents, with lower HSE impact.
Key Features of Promosolv 70ES
- Surface tension 14 dynes/cm
- Low GWP of 93
- Perfect for PCBA defluxing
What Does Promosolv 70ES Clean?
It removes reflowed flux residues and contaminants in vapor phase cleaning. Typical applications include PCBA defluxing, power modules, lead frames, BGA, PoP and SIP assemblies, and LED assemblies.
Deep Rinsing Under Components
Very low surface tension lets it rinse deep under low stand-off components. In addition, it offers short cleaning, rinsing and drying times. It is also compatible with all metals and most plastics and elastomers.
Does Promosolv 70ES Work in Humid Conditions?
Yes. Its isopropanol content reduces water absorption, so performance stays stable in humid environments. It also stays thermally and chemically stable in use.
Safety and Environmental Profile
It has no flash point and keeps its flammability suppression during equipment use. Purity is above 99.5%, with isopropanol below 3% by weight. It also has no ODP and low toxicity for safer handling.
Why Choose Promosolv 70ES?
Its high boiling point reduces solvent drag and supports continuous recycling. As a result, it extends bath-life and helps manage cleaning costs over time.
