Introduction

azeotrope-like formulation with isopropanol.

This fluid is ideal for light-duty cleaning and degreasing tasks, and is intended to replace ozone-depleting

materials such as CFC-113, HCFC-14lb and 1,1,1-trichloroethane in many applications. It has zero ozone

depletion potential and other favorable environmental properties (see Table 2). Novec 71IPA fluid has a low

Engineered Fluid component (eight hour average).

The increased polar soil solvency and low surface tension, nonflammability and constant composition

during boiling of Novec 71IPA fluid make it ideal for precision and specialty cleaning and rinsing for

removal of particulate, fingerprints and light soils from metal, plastic and glass parts.
