(1888PressRelease) June 08, 2012 - Hernon Manufacturing, the innovator in adhesives, sealants and dispensing equipment, is pleased to announce it has received independent lab verification from Intertek Automotive Research, a certified accredited lab, that its Dripstop® 940 pipe thread sealant is free of the containment's listed in ISO-22241, which are the same containment's also restricted for presence in Diesel Exhaust Fluid (DEF) applications.

In 2010, stricter EPA standards were set in place and enforcement began requiring all new diesel engines built, including boats, generators, service, public transport and fleet vehicles to switch over to DEF technology to help neutralize NOx emissions. When DEF is injected into the engine exhaust gas, it is rapidly hydrolyzed producing the oxidizing ammonia needed by the SCR catalyst to complete NOx emissions reductions.

Typically, in DEF bulk transport and transfer equipment, stainless steel fittings are used. Dripstop® 940 is specially formulated to work with stainless steel and now shows compatibility with DEF.

Hernon Manufacturing's customers within the Petroleum Bulk Transfer industry had requested a validated DEF compatible thread sealant. In response, Hernon Manufacturing submitted samples of its Dripstop® 940, an anaerobic pipe sealant, to Intertek which conducts thousands of automotive fuel and lubricant analytical tests each month. The purpose of the test was to confirm that Dripstop® 940 was containment free to ISO-22241 standards and therefore compatible for DEF technology. The product received the necessary approvals and exhibited 100% passing results for the requirements stated in the ISO-22241.

"Dripstop® 940 is ideal for use with stainless steel pipe threading, and was proven to be compatible for DEF applications by third party validation," said Harry Arnon, President of Hernon Manufacturing.

Hernon Manufacturing's Dripstop® 940 is a general purpose anaerobic pipe sealant. It has superior sealing, and has been specially formulated to be used with stainless steel pipe fittings and mild locking performance compared to tapes and non-hardening dopes. Dripstop® 940 reduces costs by eliminating leakage and increasing the assembly line speed.

"Our pipe sealant is vital for companies who manufacturer and install the equipment for bulk transfer of DEF," continued Arnon. "But, Dripstop® 940 is not just for DEF, it's suitable for both stainless steel or standard pipe thread fittings for the petrochemical industries as well."

For use on inactive metals such as stainless steel and monel , Dripstop® 940 is a high-speed thread sealant used in chemical process piping. Normally, inactive materials like stainless would require a primer to assure predictable cure. Dripstop® 940 is formulated to cure without the necessity of a primer, but, priming does reduce cure time. The enhanced chemistry of Dripstop® 940 delivers super fast cure speeds on conventional materials, like carbon steel, brass, etc. This pipe sealant withstands high pressures, sealing up to 250psig steam at 400°F (204°C) continuous service while maintaining its chemical inertness. It also lubricates threads during assembly, prevents galling, and assures smooth disassembly.

"Dripstop® 940 provides an instant seal against liquid and gas leaks at moderate pressures. For maximum pressures, the product should be allowed a full cure of 24 hours. It also eliminates waste in that there is no dripping or running," added Arnon. "Additionally, because it is solvent free it won't crack or shrink due to solvent evaporation."

Typical applications for Dripstop® 940 are: DEF bulk transfer stainless steel pipe fittings, fuel line fittings, plated flare fittings, pulp and paper mills, refinery piping, instrumentation fittings, waste treatment plants, textile equipment, piping for chlorine and caustic sodas, hydraulic line fittings, pneumatic line fittings, fluid connections, steam lines up to 250 psig and pipe plugs.
