ThermoLock™ is a high-performance, passive fireproof coating system engineered to enhance the heat resistance, durability, and survivability of critical assets in aerospace, spaceflight, and defense sectors. Developed by Doctor T Co., Ltd. in Thailand as a proprietary extension of the TPoxy™ platform (currently under IP filing), ThermoLock™ leverages advanced polymer chemistry to create a brush-applied thermal shield that performs in the most demanding environments.

The formulation is a thick cream that adheres to a wide range of substrates without requiring multi-layer priming, high-pressure spray systems. Application is straightforward—once coated, the surface is ready for use within minutes without the need for extended drying or post-curing protocols. Unlike many industrial and aerospace-grade fireproof coatings that require toxic hardeners or carcinogenic additives, ThermoLock™ contains no heavy metals and avoids known toxins such as formaldehyde—making it safer for both field personnel and end-use environments. The formulation is not solvent-free, but field results and internal testing suggest that its reactive chemistry binds most volatiles during application—leaving behind a stable, low-emission surface.

Recent field testing demonstrated ThermoLock™'s ability to withstand open flame exposure exceeding 1400°C for extended durations. During these tests, the reverse side of the coated panels remained below 100°C, underscoring its potential as a passive thermal barrier in applications where active cooling or bulk insulation are impractical. The coating retained adhesion and physical structure even under prolonged, localized flame impingement, with no burn-through or delamination observed.

ThermoLock™ has been successfully field-tested on diverse substrates including metal sheets, fiberboard, corrugated cardboard, and even raw organic materials such as meat tissue. Results confirmed high flame resistance, structural stability, and thermal shielding, with minimal surface charring and no through-layer damage. This indicates a broad applicability across composite housings, internal bulkheads, cargo modules, and fire-resistant packaging in both civil and defense-grade aerospace systems.

In defense contexts, ThermoLock™ can be applied to riot shields, mobile shelters, fire-barrier panels, and tactical gear. For aerospace and aviation, the coating can enhance the fire endurance of aircraft interiors, underfloor cabling channels, unmanned aerial vehicle (UAV) housings, or satellite payload packaging. In space applications, where mass efficiency is critical, ThermoLock™ offers a thin-layer protective alternative to traditional ablative coatings, potentially extending hardware durability during atmospheric re-entry or launch-stage exposure.

Manufacturability is highly feasible. ThermoLock™ is a single-component, room-temperature system with long shelf life, minimal mixing requirements, and compatibility with standard industrial packaging lines. This makes it ideal for deployment in conflict zones, emergency areas, or space-constrained engineering environments. Its brushable consistency allows for deployment in remote zones or low-infrastructure environments without advanced spray equipment.

By combining passive thermal resistance with ease of application, ThermoLock™ offers a novel leap over the current state of the art in flame protection—bridging the gap between bulky ceramic insulation and thin-film coatings that degrade under extreme heat. Its integration potential across aviation, space, and defense systems supports international goals in crew safety, asset protection, and climate-resilient materials innovation.
