Deep technical expertise of the founding team, strengthened by IIT Delhi's research ecosystem, enabling rigorous material development, testing and validation against industry standards and application-specific engineering requirements.
What is our technology platform for?
Our proprietary material design and manufacturing technologies enable application-specific solutions across high-altitude inflatable platforms, engineered inflatable structures, and flexible and collapsible containers.
They also serve flexible thermal insulation and signature-management applications that demand application-specific engineered materials operating under extreme conditions.
Tethered aerostat, live field deployment
IIT Delhi demonstrates indigenous AI-enabled aerostat surveillance technology
A DRDO-funded field demonstration of a tethered aerostat surveillance platform, developed through IIT Delhi's Textile and Fibre Engineering department. GB Texcoat, a FITT-IIT Delhi incubated deep-tech startup, industrialised the technology: developing and fabricating the complete aerostat system on our proprietary coated textile material.

Apex AeroTex fabrication lab.
Our in-house LTA fabrication lab takes coated fabric from the roll to a finished structure: cutting, seaming, RF welding, pressure testing and packing, all under one roof, with the same engineering team that developed the material.
RF Welding
Radio-frequency seam welding for gas-tight joints on LTA envelopes and inflatable structures.
Hot-Air Bonding
Precision hot-air bonding for thermoplastic coated fabrics and field-repair compatible seam construction.
Thermal Welding
Alternate welding technique for thermoplastic materials where RF welding does not work.
Pressure Testing
In-house pressure test rigs validate envelope integrity to burst and cyclic fatigue specification before delivery.
Four streams. Always running.
Coating chemistry
Polymer formulation across PVC, TPU, PVDF and fluoropolymer systems. Focus on adhesion, weather resistance and joinability.
Weave engineering
High-tenacity polyester and aramid weave geometries. Ripstop optimisation for tear-propagation resistance under load.
Seam & joinability
RF, hot-air and adhesive seam systems. Targeting >90% base-fabric strength retention at the joint.
Lifetime modelling
