Adhesives and sealants for India's automotive plants.
Automotive is the largest industrial user of adhesives and sealants in India, from engine and gearbox assembly to rubber-to-metal parts and body shops. It is also the strictest buyer: every product goes through trials and formal approval before it reaches the line.
Where adhesives go in a vehicle
- Threadlockers on engine, transmission and chassis fasteners.
- Formed-in-place gaskets on engine, gearbox and axle covers.
- Retaining compounds for bearings, bushes and press-fit parts.
- Metal-to-rubber bonding in engine mounts, bushes and anti-vibration parts.
- Instant adhesives for rubber profiles and small assemblies.
- Structural adhesives and sealants in body shops, and new bonding, sealing and potting needs in electric vehicle battery packs.
How automotive plants buy
Production adhesives are part of the product, so they are often written into drawings and specifications. Changing one means trials, test reports and, for parts supplied to a vehicle maker, the customer's approval. Maintenance adhesives used to keep the plant running are bought separately and much more simply.
Knowing which stream you are selling into, and who signs off in each, saves months. I wrote about this in detail: who actually decides adhesive purchases at an automotive Tier 1 plant.

How I help
For adhesive brands, I open doors at OEMs and Tier 1 and Tier 2 suppliers and keep approvals moving. For plants, I help choose the right category and coordinate trials with suppliers. See product and application support.
Questions people ask
How long does adhesive approval take at an automotive plant?
Maintenance products can be approved in weeks. Production adhesives that are part of the product often take several months, because of trials, test reports and, for Tier suppliers, the vehicle maker's approval of any change.
Which adhesives do automotive component makers use most?
Threadlockers, formed-in-place gasket sealants, retaining compounds, instant adhesives and, in rubber parts, metal-to-rubber bonding agents. Body shops and electric vehicle battery packs add structural adhesives and specialised sealants.
Do you work with two-wheeler and tractor makers too?
Yes. The same adhesive families are used across cars, two-wheelers, commercial vehicles and tractors, and their suppliers sit in the same clusters.
