The most important step in producing proper adhesion to any substrate is the first step...surface preparation. Without the proper surface preparation, any bonding attempt is very likely to fail.

Proco has been involved in rubber to Metal bonding since 1958. We have the right equipment to get the job done both correctly and efficiently. We have a dedicated 18' x 40' blast building with a dust collection system. The dust collection system removes air-borne particles created during blasting operations and keeps it from polluting the air. The blast medium is propelled with a 150HP Sulair compressor which produces an excellent profile (2-4 mil). We utilize re-useable steel grit which costs less than sand or coal slag. Our blast building is also equipped with a Clemco grit recovery system that cleans the grit of dust and debris before it is re-used.

We can perform any kind of blasting for steel parts. No job is too big. We can also blast other substrates such as Aluminum, Copper, Brass, Stainless Steel and Hasteloy.

SSPC-SP 1
Solvent Cleaning - Removal of oil, grease, dirt, soil, salts and contaminants by cleaning with solvent, vapor, alkali, emulsion, or steam.

 

SSPC-SP 2
Hand Tool Cleaning - Removal loose rust, loose mill scale, and loose paint to a degree specified, by hand chipping, scraping, sanding and wire brushing.

 

SSPC-SP 3
Power Tool Cleaning - Removal of loose rust, loose mill scale, and loose paint to degree specified, by power tool chipping, descaling, sanding, wire brushing and grinding.

 

SSPC-SP 5 (NACE 1)
White Metal Blast Cleaning - Removal of all visible rust, mill scale, paint, and foreign matter by blast cleaning by wheel or nozzle (dry or wet) using sand, grit or shot. (For very corrosive atmospheres where high cost of cleaning is warranted.)

White Blast SSPC-SP5

SSPC-SP 6 (NACE 3)
Commercial Blast Cleaning - blast cleaning until at least two-thirds of the surface area is free of all visible residues. (For conditions where thoroughly cleaned surface is required.)

Commercial Blast SSPC-SP6

SSPC-SP 7 (NACE 4)
Brush-Off Blast Cleaning - Blast cleaning of all except tightly adhering residues of mill scale, rust and coatings, exposing numerous evenly distributed flecks of underlying metal

Brush Blast SSPC-SP7

SSPC-SP 8
Pickling - Complete removal of rust and mill scale by acid pickling, diplex pickling, or electrolytic pickling.

 

SSPC-SP 10 (NACE 2)
Near-White Blast Cleaning - Blast cleaning nearly to White metal cleanliness, until at least 95% of the surface area is free of all visible residues. (For high humidity, chemical atmosphere, marine, or other corrosive environments.)

NearWhite Blast SSPC-SP 10

SSPC-SP 11
Tool Cleaning to Bare Metal - Complete removal of all rust, scale and paint by power tools, with resultant surface profile.

 

SSPC-SP 12 (NACE 5)
Surface Preparation and Cleaning of Steel and Other Hard Materials by High- and Ultrahigh-Pressure Water Jetting Prior to Recoating - Used where abrasive blasting is not feasible because the resultant flying abrasive particles and drifting dust may damage highly sensitive rotary equipment and filters, cause contamination of nearby mechanical equipment and structures or cause contamination of the environment.

 

SSPC-SP 13 (NACE 6)
Concrete Preparation - This standard gives requirements for surface preparation of concrete by mechanical, chemical, or thermal methods prior to the application of bonded protective coating or lining systems. The requirements of this standard are applicable to all types of cementitious surfaces including cast-in-place concrete floors and walls, pre-cast slabs, masonry walls and shotcrete surfaces. An acceptable prepared concrete surface should be free of contaminants, laitance, loosely adhering concrete, and dust, and should provide a dry, sound, uniform substrate suitable for the application of protective coating or lining systems. Depending upon the desired finish and system, a block filler may be required. Block (Cinder and Concrete) - Remove all loose mortar and foreign material.

 

SSPC-SP 14 (NACE 8)
Industrial Blast Cleaning - Surfaces viewed without magnification, are free of all visible oil, grease, dust, and dirt. Traces of tightly adherent mill scale, rust and coating residue are permitted to remain on 10% of each unit area of the surface if they are evenly distributed.
