Rubber linings are barrier-type linings/coverings that are applied to equipment to protect from corrosion, abrasion, and chemical attack. For decades they have proven to be a reliable choice for protection of equipment in the Chemical Processing, Mining, Power Generation/Utility, Transportation, and Water Treatment industries.
Rubber lining materials are generally broken into two categories: natural rubber and synthetic compounds (generally a blend of natural and synthetic ingredients). Some common rubber lining types and uses are as follows:
- Soft natural – concentrated HCl, as well as sliding and impingement-type abrasion service
- Semi-hard/hard natural – strong acid solutions, plating solutions, wet chlorine and ion exchange water treatment vessels
- Chlorobutyl/bromobutyl – weather/ozone resistance, sodium hypochlorite solutions, acid/caustic solutions at elevated temperatures.
- Ethylene propylene diene monomer (EPDM) – oxidizing solutions, weather/ozone resistance and certain solutions at elevated temperatures.
- Buna-nitrile – aliphatic hydrocarbons, abrasion and heat resistance
- Neoprene – good physical properties, ultraviolet (UV) and ozone resistance, slight to moderate oil resistance.
Thin-Film Linings and Coatings
Thin-film linings and coatings, by definition, are films that are less than 20 mils (0.020″) in thickness. These are generally spray-applied systems and can be used as lining systems when properly applied and holiday-tested – these can also be applied as an external coating system for protection of equipment in fume, splash, and spill exposure.
Thin-film systems used as linings require a higher standard of surface preparation than those used as external coating systems. Equipment design and fabrication quality are key in achieving a continuous lining system free of voids or defects that can adversely affect long-term performance. These lining systems are generally designed for immersion in mildly-corrosive chemical solutions, or in situations where product purity or product release is a critical factor.
Typical thin-film lining systems include:
- Baked phenolics
Typical thin-film coating systems include:
- Inorganic and organic zinc primers
- High-heat silicones
Thick-film linings are generally recognized as liquid-applied lining systems in excess of 20 mils (0.020″) total dry film thickness.
These are selected as barrier-protection for harsh chemical environments and highly-corrosive service. As such, these linings undergo a high-voltage spark test to check the lining condition for continuity.
Thick-film linings can also be utilized to provide abrasion-resistance in slurry or dry-abrasive conditions.
Typical thick-film systems include:
- Vinyl esters
- Ceramic-filled or reinforced epoxy systems
- High-build, abrasion-resistant urethanes
Arbosol® Linings and Coatings
Arbosol is a liquid-applied, plasticized, heat-cured polyvinyl chloride (PVC) lining/coating system, known generically as plastisol. Arbonite is one of the most experienced and qualified applicators of plastisol coatings and linings, going back to our early beginnings in the 1950s.
Arbosol product advantages include:
- 100% solids – NO volatile organic compounds (VOCs)
- Proper surface preparation and the use of a chemical-bonding primer provide outstanding adhesion to the metallic substrate.
- Can be applied as a dip-coating or as a spray-applied coating system that allows for proper, continuous application on complex shapes and configurations with no seams.
- Range of durometer hardness options from 70 Shore A to 90 Shore A.
- Versatility – can be used as a tank lining system (minimum thickness of 60 mils) or as an effective barrier coating for the exterior of tanks, piping, and skids.
- Lining applications include sodium hypochlorite storage vessels, transport equipment, filter vessels in ion-exchange systems, plating equipment, and a large variety of pumps and valves.
- Food and Drug Administration – (FDA) – approved and National Sanitation Foundation (NSF)-61 certified versions available.
- Variety of colors available in spray versions; standard dip formulations are black.
