Antistatic coating for hazardous area enclosures

Intertec has launched an advance in antistatic surface coating treatment for its GRP (glassfiber reinforced polyester) outdoor enclosures. Developed specially for Intertec by the chemical specialist BÜFA, the new nanotechnology-based coating also boosts protection against damage from ultraviolet radiation - helping to achieve extended maintenance-free lifecycles of field-based control and instrumentation equipment in processing industries such as oil, gas, chemicals and petrochemicals. Intertec's weathering tests in an environmental test chamber have demonstrated that the new coating can withstand extended exposure to very high UV levels - providing a new level of protection particularly for GRP field enclosures destined for environments such as deserts, the tropics or the Arctic.

Dubbed GO-Antistatic, the new treatment is based on an advanced carbon nanotube material that is applied as part of a surface gelcoat. Polyester gelcoats are widely used to add glossy and highly durable surface finishes to the exterior of GRP enclosures. The advanced nanomaterial provides a degree of conductivity for the outdoor enclosure that dissipates any static electric charges safely to ground - to protect against sparking. Such treatments ensure safety in hazardous areas of processing plants, where a spark caused by the build up of an electrostatic charge can cause an explosion of gas, vapour or dust in the local atmosphere.

Gelcoats are a premium form of protection, and form a chemical bond on the surface of the GRP. Most of the antistatic treatments applied to GRP enclosures today rely on the addition of conductive materials into the surface gelcoat (or conductive paint) by employing carbon/graphite, tin or other metals. However, if the gelcoat contains antistatic material, this can have a detrimental effect on its performance, notably in terms of reducing its smoothness and ultraviolet protection, and limiting the colouring possibilities. Extended exposure to high UV levels can then damage GRP enclosures, leading to minor surface roughening - which is sometimes referred to as chalking or frosting.

Intertec and BÜFA worked together to develop the new antistatic coating. BÜFA chose single-wall carbon nanotubes (SWCNTs) to provide the required conductivity and has developed proprietary techniques to disperse the SWCNTs in the coating material. This approach provides numerous benefits largely because SWCNTs are incredibly small - around 1-2 nanometers in diameter - which increases smoothness at the surface level of the coating. The gloss retention (smoothness) after accelerated weathering tests is about 50% better than the previous formulation, and is on the same level as non-antistatic gelcoats. This significantly improves UV resistance, and additionally virtually eliminates any effect on the use of any decorative colourings. 

This latter advantage means that Intertec can also now provide hazardous area enclosures in a much broader range of colours than was previously possible. Options will include almost pure white for example - which will further aid solar protection, something that is very difficult or impossible to achieve with many current antistatic treatments. Intertec can also now provide enclosures in colours that match a client's corporate branding for instance, or help with other desirable attributes such as camouflage or blending with architecture.

    Intertec Instrumentation produces protective enclosures for field-based process instrumentation and control equipment, using glass fiber reinforced polyester (GRP). This material offers remarkable advantages for oil and gas applications (including natural corrosion resistance, low weight, extended durability for long life applications, much higher thermal resistance than metal – making it easier to insulate against heat and cold – and benign environments for wireless communications). Our broad range of enclosures, cabinets and shelters, plus a comprehensive selection of accessories including heating and cooling components, protect against freezing, condensation, solar radiation/UV, explosion, fire, corrosion, impact, etc. We have designed and shipped over a million instrument protection enclosures since 1965, to protect equipment operating in the most demanding operating conditions on Earth - from Arctic regions to deserts to harsh coastal and offshore environments. Application-specific protection may be configured using free software tools. Or, Intertec will configure a turnkey solution for you, using know-how that has evolved over more than 40 years. Intertec manufactures in Sarnia, Ontario, and a site in Houston, Texas with local assembly and system building capabilities.

Selecting the Right Solid Tires for Industry Specific Applications

Approximately twenty years ago, those of us working in the off-road heavy equipment industry regularly witnessed a high amount of failures in machines operating on cement or other hard surfaces. Extended steel rims were used with small, hard, rubber wheels. When these rubber tires chipped and chunked, vibrations and bouncing sent shockwaves into the machine, causing shortened life and expensive repairs, not to mention stress on operators. Drivetrain components (U-joints and articulation joints) in particular often suffered from stress cracks caused by vibrations and a bouncing machine.
