Don't Let A Little Fastener Become A Big Problem


Providing high-volume material application in a quality-conscious environment.

Pre-applied technology is normally used on high-volume parts. Therefore, customers can use the coated parts with automatic assembly equipment, with the guarantee that the product is applied correctly. With pre-applied solutions, there is no need to apply adhesives, sealants or any other locking or sealing material during assembly.

IEPPL’s Pre-Applied Application Center at Rajkot, is where it all comes together. Once a customer has selected the Loctite product which meets their specifications, un-coated fasteners are shipped from a manufacturer or distributor to our Rajkot application center.

Once on-site, our Supervisors and Machine Operators carefully direct and monitor each part as it is processed—sometimes for multiple materials.

We also offer services like part sorting, color coding, and even partial assembly, specially designed to make subsequent assembly simple, fast, and more accurate.

Types of Pre-Applied Coatings on Fasteners

Locking & Sealing of Threads

Loctite Dri-Loc® is a dry coating adhesive that contains a micro-encapsulated activator that is suspended in a water based resin. The Dri-Loc® is applied to the bolt and remains inert and dry to touch until the bolt is used. Based on the principle of prevailing torque, inert thread locking processes create fasteners with instant retention and sealing properties along with the added benefit of adjust-ability and re-usability. Inert thread-lockers are highly chemical resistant and eliminate the need for costly lock washers, cotter pins, or castellated nuts.


Instant Sealing of Threads

Loctite Dri-Seal and Vibra Seal pre-applied thread sealants are dry-to-touch, tough, non-hardening sealants engineered to be pre-applied. Designed to provide an instant seal against most fluids, fuels and lubricants on threaded fasteners, fittings, plugs and pipe joints. These products perform on demanding requirements of automotive, truck and agricultural equipment manufacturers. As they do not lock the threaded components, disassembly is easy. (For sealing + locking see Dri-Loc ® products).


Elimination of Thread Seizure

Capable of withstanding temperatures of upto 650°C. This pre-applied high temperature, anti-galling, thread lubricant product is dry to touch and offers instant sealing of most fluids & thread protection in corrosive environments. Reusable upto five times, anti-seize will perform on all part finishes and eliminate high temperature galling. The product is non-curing and completely inert at any times. Lubricates threaded parts exposed to high temperatures allowing easy disassembly. Lubricating properties reduces threaded friction, lowering applied torque for required bolt force.

Reactive Sealing Technologies

Pre-applied reactive sealants are designed to withstand a wide range of pressures, chemical fluids and gasses. Coated onto your fasteners at our factories, the sealants arrive dry to the touch. Once installed into a mating part, the reactive components mix, initiating a chemical reaction which cures the material.


Masking & Lubricating

A range of processes developed to prevent fastener seizing, reduce installation torque, limit material adhesion, and more. Our masking and lubricating processes help customers decrease assembly and disassembly time which leads to an increase in productivity. Pre-Applied fasteners are ready for use right out of the box with no curing or drying required.


Assembly Aids

Processes designed to make assembly SAFER, EASIER and FASTER by reducing application errors and worker fatigue. Depending on your needs, we can also provide auxiliary assembly of components to reduce the number of parts inventoried and minimize cost.
