Simply put, a Thread sealant prevents leakage of gases and liquids from pipe joints. Besides creating fluid-tight seals, a pipe thread sealant also lubricates the threads, making assembly quicker and easier.

Loxeal anaerobic thread sealant are high performing chemical-based thread and pipe joint compounds that cure to form a tough, non-soluble, thermoset seal between thread flanks regardless of torque applied. The seal formed by Loxeal anaerobic thread sealant work in both static and dynamic applications involving high levels of vibration and impact forces. Yet, they are easy to disassemble and seal up to burst pressure in most applications.

Being anaerobic, the Loxeal remain in liquid form until it is isolated from oxygen and metal ions. As soon as the Loxeal is applied on fitting (contact with metal is formed) and fitting is assembled (oxygen is excluded), product curing starts and seal strength starts developing.

Pipe joints are designed to be disassembled for service or maintenance. Due to this inherent design requirement every thread joint has a spiral gap at the joint interface of male and female which must be filled and packed by another suitable material to form a leak free joint.

Because Loxeal Thread Sealants are in liquid form, they fill these spiral gaps and the surface imperfections between the thread flanks perfectly to form a 100% true surface to surface contact thereby forming a barrier for fluid leak.

After curing Loxeal Thread Sealant converts itself into a tough, thermoset plastic that cannot be melted, softened or dissolved. This tough barrier or seal provides a life time of seal under both static and dynamic conditions. In today’s world leakage is not acceptable in any industrial or consumer setting and Loxeal Anaerobic Thread Sealants ensure that everytime.

A Loxeal Thread Sealant create 100% surface to surface contact between thread flanks and form a true barrier that operates under the most extreme of operating environments.

But if a picture speaks a thousand words, two pictures make it even better. Not only does Loxeal Thread Sealant form the most reliable seal, it enhances aesthetics and unitizes assembled joints.

In today’s fast paced working environment, water or oil leakage from machines or equipment can create serious production bottlenecks and safety issues. Every end user needs a trouble free system and that’s why Loxeal Thread Sealant are the top choice for most professionals. They offer many unmatched advantages over both traditional and other contemporary sealing methods. Some of them are:

In today’s world it is no longer acceptable for any machine or equipment to leak oil, water or gas. Hence, the selection of a thread sealant must be carefully done during the design stage, considering the many variable factors a pipe joint will undergo during its service life. Joints must remain leak free under the most extreme vibration, chemical attack, heat, and pressure.

Liquid gaskets are FIP (Form In Place) paste consistency sealants that have the ability to fill the surface roughness between the flanges perfectly and form 100% true surface to surface contact thereby creating a highly reliable seal. The key to the success of Loxeal liquid gaskets in automotive and many other manufacturing applications over conventional gaskets lies in the fact that they form 100% surface to surface contact without having to produce highly finished flanges.

Loxeal liquid gaskets:

Because every application is unique and demands specific performance expectations, at Elixir we provide different liquid gasket technologies to meet most application challenges.

The universal appeal of Loxeal liquid gaskets is due to some unique benefits they provide over traditional compression and cut gaskets such as cork, paper, metal and elastomeric gaskets like rubber and O-rings.

Loxeal anaerobic form in place liquid gaskets cure when in contact metal and in absence of air. Rate of curing depends on environment temperature and product type. They are 100% solids and fill surface imperfections to form a 100% metal to metal contact eliminating any potential leak paths.

Anaerobic liquid gaskets offer many benefits over traditional compression or cut gaskets:

Depending on the flange design, substrates and other parameters following are some of the important thumb rules to consider.

Surface Finish: Because Anaerobic liquid gaskets seal by forming bond/adhesion, surface finish plays a very important role in successful flange sealing. It is important to maintain surface finish between Ra 0.8µm (Rz to 3 µm) to 3.2µm (Rz 21 µm) to form a good anchoring gasket joint.

Surface Flatness: Should be maximum 0.1mm over 400mm

Bolt Span: Bolts should be placed not more than 10 bolt diameters apart. For example, for a nominal bolt diameter of 10mm, spacing between bolts should not be more than 100mm.Similarily bolt span to flange width should fall under following rules.

Chamfering: Dowels, bolt holes and edges should be chamfered to ensure that the sealing surface is free from raised metals that can cause shimming effect.

Application: Product should be applied in continuous bead form every time inside and also around the bolt holes to eliminate and chances of secondary leak path.

Bolt Torquing: For successful gasketing when working with anaerobic liquid gaskets, all bolts must be torqued as per specification as soon (<3minutes) after the assembly.

Fixture Time: Maximum possible fixture time must be allowed before pressure testing. If online testing or short term pressure test must be carried out, flange width, curing speed of Loxeal anaerobic liquid gasket, viscosity and flange gaps will play important role in time determination.

Dowels: Dowels must be provided for large sealing surfaces for proper alignment and avoiding shearing of liquid gasket.

RTV Silicone gaskets cure by reacting with surface and atmospheric moisture and convert from liquid/paste to an elastomeric gasket that seals by adhesion and forming 100% metal to metal contact.

The application of RTV Silicone gaskets is done by applying in the form of bead. After the flange joint assembly extra material squeezes out both inside and outside the joint and forms a secondary seal.

Key benefits of Loxeal RTV Silicone gaskets are:

When working with RTV Silicone gaskets, following parameters can provide the successful outcome.

Cured in place liquid gaskets are the unique and newer gasketing technology combining the advantages of compressed solid gaskets and liquid adhesives. Cured in Place gaskets (CIPG) perform by adhering themselves permanently to one of the sealing flanges and forming a seal through compression of cured gasket on the other side. The other major advantage of this technology is offering great productivity (particularly in UV technology) by curing in seconds when exposed to Ultra Violet lights.

Cured in Place (CIPG) gasket technology needs more care and precision in application to form consistent bead size, position and film thickness in continuous mode. Application using automatic or semi-automatic dispensing systems should be preferred.

Gasket dressing compounds are both solvent based and 100% solid materials designed to be used along with a compression or die cut gasket to fill the surface imperfections 100% and also enable easy disassembly during service. They come in both curing and non-drying, non-setting versions to enable different end use applications.

A non-setting dressing gasketing sealant does not harden even at high temperatures and breaks cohesively when flanges are pulled apart leaving traces of sealant on both the sides. When flanges are assembled back, the sealant joins itself again in a self-healing mechanism. This makes them ideal for sealing close fitting machines flanges in combination with a compressed gaskets.They resist high temperature and vibrations and remain impervious to most industrial fluids.

Every end application is unique and that’s why at Elixir we have liquid gasket solutions in various formulations to meet most customers’ demands. Yet there are conditions and end requirements where liquid gaskets have few limitations and are not always suitable.

1. Applications requiring frequent disassembly such as a few times in a day. Loxeal liquid gaskets are not recommended.
2. In applications where continuous operating temperature exceeds 300° such as in engine cylinder head or high temperature oven doors.
3. When surface gaps exceed 6mm, Loxeal liquid gaskets though can work but are not feasible from a practical perspective.

MMAs or Methyl Methacrylate Adhesives are 2 component structural grade acrylic adhesives that comprise of an Adhesive (Part A) and an Activator (Part B). When Adhesive and Activator are combined and mixed the product cures rapidly at room temperature exothermically to form a tough, thermoplastic adhesive capable of withstanding extreme stress, vibrations, impact forces and having excellent shear and peel strength. While the above description may sound similar to an epoxy adhesive but in reality, a Methyl Methacrylate adhesive cure profile and ultimate bond performance is much different and, in most cases, more stronger and fatigue resistant than an epoxy adhesive. The progress of curing reaction in a methyl methacrylate adhesive is slow until it reaches its pot life/open time and subsequently the fixturing strength is reached rapidly in very short time duration reducing the need for expensive fixtures and saves time before the parts can be assembled. Surface preparation requirements are not as stringent with Methacrylate adhesives.

The term Structural bonding refers to joining parts with an adhesive capable of withstanding high levels of stress and their ability to transfer load for long time period. Scott Bader MMA adhesives are one of the widely used structural bonding adhesives because they are formulated using impact modifiers to provide tough yet flexible bond lines that can withstand high shear, peel, cleavage and impact forces. Due to their toughness and high peel force resistance, they can replace mechanical fastening such as riveting, welding and bolting in a variety of applications.

Our methacrylate adhesives can bond a variety of substrates making them an ideal adhesive to bond two different substrates.

Stroke of a caulking dispenser is the distance a plunger travels with one complete pull of the trigger

Force is the amount of effort applied to pull the trigger.

Stroke and Force are inversely proportional. The lower force a dispenser needs to operate, the more number of strokes or pulls it needs to complete the job. Read how stroke and force influence the switch to a powered sealant applicator.
