Promosolv 70IS DT is a non-flammable defluxing solvent from Inventec Performance Chemicals, formulated with the Promosolv AD70 additive to tackle stubborn reflowed flux residues. It shares similarities with the standard Promosolv 70IS but is intended exclusively for use in cleaning tanks, with rinsing carried out using standard Promosolv 70IS.
Promosolv 70IS DT Features
- Formulated with the Promosolv AD70 additive for enhanced cleaning of stubborn flux residues
- Formulated with isopropanol, making it less prone to water absorption in humid environments
- Low surface tension (14 dynes/cm at 20°C), allowing deep rinsing under low stand-off components
- Excellent flammability suppression properties, formulated for safety
- Thermally and chemically stable in use
- Compatible with metals and most plastics and elastomers
- Supports continuous recycling in equipment for a long bath-life
- Non-flammable, with no flash point
Purity of Promosolv 70IS DT is greater than 99.5%, with an isopropanol content of less than 3% by weight. The product has a global warming potential (GWP) of 91, no ozone depletion potential (ODP), and very low toxicity, and its high boiling point helps reduce solvent consumption.
Applications
- Removal of reflowed flux residues and contaminants
- PCBA defluxing
- Power module cleaning
- Lead frame processing
- BGA, PoP and SIP assembly cleaning
- LED assembly cleaning
Promosolv 70IS DT is used in vapor phase cleaning processes, with parts rinsed using standard Promosolv 70IS. Used product can be returned for recycling and re-use through Inventec’s Ecoprogram solvent recovery service.
