VpCI 429 Surface Prep

VpCI-429 is a very effective rust remover and cleaner for different metals. The chemistry of this product is based on the chelating abilities of its ingredients.

VpCI-429 not only completely cleans rusted surfaces, but also prevents further rusting during the cleaning process. After cleaning there is no need for neutralization or additional rust preventative materials.

VpCI-429 is very environmentally and user friendly, has a neutral pH, is made out of biodegradable and renewable materials, is non-irritative and not harmful. Metal surfaces treated with VpCI-429 can be painted without any problems, eliminating the step of additional preparation. In most cases VpCI-429 acts as an adhesion promoter for coatings.

Rust Removal:
VpCI-429 is used in dip applications.

  • Step 1: Pour into a container a sufficient amount to completely cover the rusted metal.
  • Step 2: Leave the metal in the solution for 15-30 minutes (light rust) or up to overnight (very heavy rust).
  • Step 3: Rinse treated metal with water. If some rust still remains on the surface, repeat step 2.
  • Step 4: After rinsing, dip the metal into a clean solution of VpCI-429 and allow to air dry. This will prevent rust for up to 4-5 weeks.
