Inventec Promosolv 70ES cleaning and flux removal solvent

Inventec’s Promosolv 70ES has been developed as a specialty solvent to clean the residues from solder pastes and solder fluxes. The high-tech fluid has no ODP, good chemical stability and low toxicity, resulting in a product is designed to be safe to use and environmentally friendly.

The solvent is an azeotropic formulation of the methoxynonafluorobutane (C₄F₉CH₃), trans-1,2-dichloroethylene and ethanol, and is clear and colourless with only a slight odour. It is designed to replace existing solvents with an ODP and to be used with ultrasonic cleaning.

The formulation is designed to provide an increased solvency power over the Promosolv 70. Its medium-range boiling point and its low surface tension provide the product with good flux removal and drying characteristics when used in vapour phase with azeotropic mixtures.
