Our Solutions

metal pretreatment services

Surface coating pretreatment from RIE Coatings removes surface blemishes and changes the substrate texture to prepare the surface for further processes like painting. Our industrial pretreatment process includes sandblasting or bead blasting and chemical paint stripping. These steps result in quality pretreated substrates with a primed surface for adhering coating materials.

Sandblasting and Bead Blasting

Sandblasting and bead blasting are abrasive methods used to treat and prepare surfaces. Sandblasting is more aggressive, making it ideal for heavy-duty applications like removing rust on large areas. On the other hand, bead blasting is better for precision cleaning and finishing work where a less aggressive technique is required to avoid damaging the substrate.

RIE Coatings will help you prepare your aluminum and steel surfaces for coating with sandblasting or bead blasting. We’ll assess your project requirements and the material being treated to determine which technique is right for you.

Sandblasting

Sandblasting propels an abrasive against the surface under high pressure. Our sandblasting treatments use aluminum oxide as the sandblasting abrasive. The grains are angular, durable and small, making aluminum oxide effective for:

  • Smoothing
  • Roughening or texturizing
  • Polishing
  • Shaping the surface
  • Removing contaminants like rust and scale
  • Deburring
  • Grinding
  • Rounding off edges

Our sandblasting services meet MIL-A-21380, 9906020 and SS-PC-SP-SXX specifications.

Bead Blasting

Bead blasting applies beads at high pressure to a surface to create a uniform finish and remove deposits without causing damage. RIE uses glass beads because they:

  • Clean surface blemishes like paint, scale and rust.
  • Polish the surface.
  • Debur sharp, rough edges.
  • Peen the metal to improve its mechanical properties.
  • Prepare the surface for further processes.

RIE recommends bead blasting for stainless steel, chrome, copper, aluminum, metal, plastic and rubber.

Paint and Metal Stripping

Chemical paint stripping — industrial paint stripping — removes paint, finishes and coatings while cleaning the underlying surface. Caustic chemical paint strippers break down the chemical bonds of paint, and solvent chemical paint strippers weaken the bond between the paint and the surface.

Paint and metal stripping is a low-cost technique for cleaning complex parts and is typically safer for the substrate than mechanical stripping. Chemical stripping is suitable for numerous materials, from painted surfaces and wood to plastics and metals.

RIE Coatings uses these types of strippers:

Cold Strippers

Cold strippers are a blend of:
  • Chlorinated solvents.
  • Methanol.
  • Methylene chloride or ethylene dichloride.
  • Acetic, ammonia or formic acid.
  • Additional solvents needed for the coating.
Using cold strippers removes coatings and paint with minimal corrosion, low inflammability and a high flash point, leaving the work surface clean and ready for refinishing.

Stripping a substrate with hot solvent emulsion strippers involves soaking the part in an emulsion or spraying the surface. The water-to-stripping concentrate ratio means the coatings are removed from the metal surface without damaging the substrate. These strippers work best for removing alkyd, melamine, phenolic, epoxy and urea coatings.
