Product Name : VDR-SC

(De-rusting & de-scaling Chemical)

Introduction 

Hydrochloric Acid based De-rusting chemical with corrosion inhibitors and wetting agent designed to remove oxides and black scale from the rust surfaces. It is especially useful for HR components.

 Scope

VDR-SC is an inhibited hydrochloric acid based chemical used for removing black oxide scale / heat treatment scales
and heavy rust from ferrous surfaces by immersion method, operated at room temperature. Metal loss is negligible,
due to inhibited action. We recommend to install scrubber for removal of corrosive fumes.

Product Name : VDR-VAM

(DE-RUSTING CHEMICAL FOR FERROUS MATERIAL)

Introduction

Phosphoric Acid based chemical with organic and inorganic acids designed to remove oxides from the surfaces. It is especially useful for CR components.

Scope

Read More

VDR-VAM is a phosphoric acid based rust removing chemical along with mixture of other mineral acids. It is
formulated to ‘de-rust’ the iron and steel components prior to phosphate coatings. It contains special additives
and inhibitors which minimizes the excessive etching and helps to produce phosphate coating in smooth and
uniform manner. The removal of oxide scale and heavy rust can be accelerated by heating the bath up to 500C.

Product Name : VDR-PK

(DE-RUSTING CHEMICAL FOR CAST IRON)

Introduction

Phosphoric Acid based chemical with noble wetting agents and surfactants designed to remove oxides and rust from surface. It is especially useful for casting components.

Scope

Read More

VDR-PK is a phosphoric acid based chemical especially formulated for the rust and entrapped silicate removal from
cast iron surfaces. Excessive metal attack is minimized by incorporation of suitable inhibitors. The de-rusting
process helps to achieve the cleaning in thorough from the porous CI surfaces, which promote the paint adhesion
with better corrosion protection.
