Cleaning and flux removal solvent for electronic assembly - Replace Trichloroethane, ODP & Bromide Based Solvents

Promosolv 70ES is a specialty developed solvent to clean the residues from solder pastes and solder fluxes.

Promosolv 70ES of INVENTEC is a pseudo-azeotropic formulation of the methoxynonafluorobutane (C4F9CH3), 1,2-trans-dichloroethylene and ethanol.

Promosolv 70ES is clear, colourless, and has a slight odor. It is designed to replace the existing solvents having an ODP and to be used with ultrasonic cleaning. Its medium-range boiling point of 43 Celcius and its very low surface tension provide outstanding flux removal and drying characteristics when used in the vapor phase unit.

Promosolv 70ES formulation provides an increased solvency power over the Promosolv 70, in particular for most of the polar and ionic compounds.

This High-Tech fluid has no ODP. Its chemical stability and its very low toxicity result in a product that is safe and which is environmentally friendly.

This product is not flammable in the standard conditions of use or storage. This fluid is highly stable to thermal and to chemical reactions when used in normal conditions. Some more procedures are detailed in the safety data sheet available upon request. This product does not sustain combustion according to the norm: ASTM D4206-86 (< 1 second). To ensure the best product performance, it is recommended to store the products in closed packaging types. The shelf life of the product: 18 months under these conditions.

As with most fluorinated liquids, this fluid is absorbed by the plastics and the fluorinated elastomers in case of prolonged exposure.

Tests show good compatibility with a large range of metals, plastics, and
elastomers, similar to the performance of perfluorinated liquids. Good compatibility with plastics particularly sensible as the polycarbonate and the PMMA indicate a possible use in the cleaning unit containing numerous components.
