UniPrep® – Iron Phosphate Alternative for Paint Pretreatment

UniPrep® replaces iron phosphates and eliminates many of the problems associated with this traditional approach. UniPrep® reduces overall process costs by operating at lower temperatures, extending cleaner life, reducing downtime, minimizing rejects, and decreasing waste treatment burdens. This breakthrough paint pretreatment technology provides consistent surface preparation, leading to optimal performance on multiple metal substrates.


UniPrep® Cleaners

UniPrep® cleaners operate at low temperatures (35 - 50°C), contributing to a safer, more comfortable work environment. Along with highly emulsifying surfactants, some UniPrep® cleaners utilize bioremediation for a superior cleaning process. Bioremediation is the natural process of breaking down organic molecules, such as soils removed during cleaning, which extends the service life of the cleaning solution.


UniPrep® Adhesion Promoters

UniPrep® adhesion promoters were formulated to work directly with long-life, low temperature cleaners, providing excellent adhesion performance on various metal substrates. Metal and acid-free, UniPrep® adhesion promoters do not require post-application rinses and preserve metal surface appearances for clear-coat applications.

UniPrep® adhesion promoters also eliminate scale and sludge formation and significantly minimize waste treatment requirements. UniPrep® adhesion promoters operate at ambient temperature while providing performance comparable to iron phosphates.
