Tech Specs

SWHTR®EnviroPaste (Stainless Weld Heat Tint Remover – PASTE formula) is a high-performance, patented, 2-in-1 product that pickles and promotes passivation for all grades of stainless steel. In 1 step, it quickly and effectively removes heat tint discoloration and free-iron contamination from stainless steel surfaces. Unlike
traditional, toxic products, 

SWHTR®EnviroPaste is biodegradable and uses “Smart Chemical Technology”
that is FREE of hydrofluoric acid (HF) and encourages homogenous passivation when applied.

SWHTR®EnviroPaste is fume-free and easily applied by either a caulking tube, by brush or by specialty
sprayer depending on the surface area to be treated. It is safe to be used on surfaces for extended / long term dwell times without pitting, discoloring, corroding or damaging the healthy metal. As a non-dangerous
goods product, it is easy to ship and store.
This advanced, water-based paste is the only non-toxic chemical pickling product commercially available.

SWHTR® EnviroPaste replaces dangerous hydrofluoric acid and nitric acid-based products, many of which
are banned or becoming highly regulated. It also eliminates the need for mechanical methods which can
release dangerous hexavalent chrome particles into the air. 

SWHTR®EnviroPaste complies with the highest
levels of regulation and improves health and safety conditions onsite. It is the only known pickling product
available in a caulking tube and the only one that can safely be sprayed on large areas.

SWHTR®EnviroPaste is the best choice to ensure safe and effective pickling and proper passivation every time to improve weld zone corrosion resistance and avoid in-service weld zone failures. It comes ready to use and complies with ASTM A380 “Standard Practice for Cleaning, Descaling and Passivating of Stainless Steel Parts, Equipment, and Systems”
