PROMOSOLV DE4
- Removal of flux residues
- Vapor phase process
- Excellent cleaning & low HSE impact
PROMOSOLV DE4 is developed as a drop-in replacement for trichlorethylene, NPB and other solvent. While reducing substantially the HSE impact, the defluxing power is at an equivalent level. Besides, it is an equivalent to the phased out Novec 72DA as it has the same proportion of components and same properties.
It is dedicated for removing reflowed flux residues and other contaminants on PCBA’s, Power modules, lead frames, BGA’s, PoP or SIP applications & LED assemblies. Its low surface tension allows very well cleaning and rinsing under low stand-off components and difficult to reach spaces. It has very good compatible with all metals, including very sensitive ones and also with most plastics & elastomers, however recommended to validate before use.
PROMOSOLV DE4 is formulated with safety in mind. Its composition gives excellent flammability suppression properties, which provides a very high stability when used in an equipment. Some products in the market may loose their flammability suppression compound due to evaporation when used in an equipment.

Benefits
PERFORMANCE
- Thermally and chemically stable in use
- The very low surface tension allows deep rinsing under low stand-off components
- Short cleaning, rinsing and drying times
COST
- Continuous recycling in equipment for a long bath-life
- Can be returned for recycling and re-use
- The relative high boiling point reduces risk of solvent drag, so limiting consumption
HSE
- Very low toxicity
- No Ozon Depletion Potential (ODP)
- Low Global Warming Potential (GWP)
- Non-flammable
Process examples
Removal of flux residues
- Do not remove parts too quick out of the drying zone to prevent unwanted loss of solvent.
- Compatibility report with different materials is available on request.
- In case of very heavy production load, Promosolv AD70 additive can be added to increase solubility of solder fluxes.
- It’s recommended to work with a siliporite filter to separate water from the condensation loop.
