Inventec Co-solvents

Precision cleaning processes

1) Separated co-solvents

2) Combined co-solvents & detergents

3) Water displacement drying

Co-solvents formulations

1) Co-Solvents:• 3 sumps: Solvents, co-solvents, drying agents• Formulated to dissolve specific contaminants without damaging other materials

2) Combined Co-Solvents & Detergents:• 4 sumps: Solvents, Co-solvents, detergent, drying agents • Can clean organic and non-organic parts

• Superior cleaning power (Kb value > 100, specific targeting of contaminants, deeper cleaning via low surface tension, perfect finishing via drying).

• Up to 4 X less expensive than water based cleaning (Capex, water, waste water disposal)

• Safe & environmentally friendly: Non-chlorinated, non flammable and non toxic.

• Smaller surface footprint

Benefits / Customer value:

Spot Free Precision Drying

Process - Water displacement:1. Dip and displace water into the 71DS22. Rinse N°1 into 71IBuA3. Rinse N°2 into 71IBuA4. Vapor Rinsing5. Condensation drying

Advantages:• Spot free, no halo, no smudge• Super fast drying: 30 sec. to 2 min • Very low surface tension• Low temperature parts / can handle by hand• Non flammable, Non-toxic and Non-explosive• CAS, non-VOCs, -HAPs, -ODCs, -GWCs• Products are reclaimable, no disposal needed
