Perspectives from industry authority Dr. S.C. Srivastava, presented at the Paintvision Global Business Summit 2026.
For over five decades, the global coatings industry operated within a perimeter of relative predictability – an era of conventional surface science defined by the stable chemistries of alkyds, epoxies, and standard polyurethanes taught to mid-20th-century graduates. As Dr. S.C. Srivastava puts it, the industry has now moved beyond that era of incremental growth into a VUCA (volatile, uncertain, complex, and ambiguous) environment, where the foundational technologies of the past are no longer sufficient. The transition underway is from “passive protection” to “intelligent functionality” – and it demands a strategic, bird’s-eye view of the disruptive technologies set to define the next decade of surface science.
The Rise of Smart Coatings: Materials with Memory and Response
The strategic importance of “smart” functionality lies in the shift from coatings that merely sit on a substrate to those that actively respond to their environment – no longer speculative science, but the new benchmark for high-stakes asset protection. Self-healing and anti-corrosion formulations now repair physical damage autonomously, a non-negotiable requirement for the longevity of aircraft, maritime vessels, and space exploration equipment. Responsive and shape-memory materials are emerging too – thermochromic and photochromic coatings that adapt to heat and light, alongside “shape-memory” crystals that let a coating remember its original molecular structure. On the physical-property side, the future belongs to super-hydrophobic and anti-fog surfaces that redefine maintenance cycles for modern infrastructure.
One area worth particular attention is EMI/EMF shielding. As global airport expansion accelerates, interference from high-density electronics has become a critical safety liability for air traffic control, pushing the industry toward conductive and semi-conductive coatings that manage signal dissipation. The engineering focus has shifted from simple conductors or insulators to mastering the crucial semi-conductive dissipation range via nano-additives – essential groundwork for the next generation of electromagnetic shielding.
The Green Transition: Eliminating Toxins and Microplastics
Sustainability is no longer a marketing elective; it has become a response to a looming biological crisis. The “menace of microplastics” has moved from an environmental concern to a human one, with polymer emulsions now detected in human blood and bodily fluids – a trend Dr. Srivastava links to a sobering human cost, including rising infertility and gynecological complications as microplastics infiltrate the global food chain.
Traditional chemistry is facing a serious regulatory and ethical reckoning. Reliance on bisphenol-A based epoxies and toxic isocyanates (TDI, MDI, HDI, and PDI) is drying up, and MEK oxime – widely used as an anti-skinning agent – is being recognised as a narcotic byproduct with no future in a responsible market. UV-cured systems, once the frontier of the industry, are similarly being phased out as their skin-irritant initiators lose favour, with electron beam (EB) curing emerging as the cleaner, safer successor.
In their place, the industry is pivoting toward a circular economy built on high-performance bio-chemistry: non-isocyanate polyurethanes (NIPU) that eliminate toxic hardeners, bio-polymers such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), renewable resins like furan resins and lignin-based phenolics, and natural sources such as tannin-based resins derived from vegetable sources like triphala. It’s worth distinguishing genuine bio-chemistry from “political hype” here – materials like cow-dung paints capture headlines but lack the technical stability required for industrial sustainability, whereas starch modifications and glyoxals offer real performance parity.
High-Performance Pigments: Phasing Out Carcinogens
As the resin backbone evolves, the pigments providing colour must undergo a similar purge. Benzidine-based azo-pigments are known mammalian carcinogens that degrade dangerously during high-temperature recycling, and even standard carbon black is facing obsolescence in the circular economy because it interferes with non-infrared sorting processes at recycling facilities.
The industry is moving toward high-performance organics such as DPP (diketopyrrolopyrrole), perylene, and benzimidazolone. There’s a geopolitical dimension worth watching too: India and China currently control the supply of carbazole and chloral, the essential precursors for Pigment Violet 23, meaning supply chain stability in this new frontier depends on navigating regional dependencies while integrating nano-pigments that offer unprecedented weather fastness.
Sustainable Pre-Treatments: The Move Toward Waterless Systems
The best coating is only as good as the surface it bonds to, and traditional, water-intensive, chemically hazardous pre-treatments are being replaced by frontier technologies that eliminate heavy chemical runoff – silane-based treatments in place of phosphoric acid pickling, laser cleaning and plasma treatment replacing sandblasting, dry ice (CO2) blasting instead of heavy phosphate conversion coatings, and enzymatic liquid aqueous cleaning replacing strong chemical baths. Beyond cleaning, plasma surface treatment using highly energised radiation and electrochemical activation is enabling nano-structured surface preparation that ensures superior adhesion without the environmental toll of acid baths.
AI and Machine Learning: Reducing Years to Minutes
Artificial intelligence is re-engineering the R&D landscape to the point where predictive modelling can compress the R&D cycle of a complex formulation from several years down to minutes. Intelligent formulation design – using random forest models, artificial neural networks, and deep learning – is optimising pigment dispersion and cost-to-performance ratios. Computer vision is surpassing human visual inspection entirely, with modern machine vision processing up to 10 million frames per second, catching microscopic defects that would escape the human eye. And the industry is moving beyond simple SCADA/PLC systems toward digital twin cloning – digital replicas of coating systems that allow real-time simulation, predictive maintenance, and environmental impact optimisation before a single litre of paint is produced.
Beyond the “Copy-Paste” Mindset
This transition demands a fundamental shift in professional philosophy. Dr. Srivastava frequently invokes the metaphor of “replacing a fly with a fly” – a blind cut-copy-paste engineering mindset, exemplified by a painter who replicates a stray fly on a canvas simply because it appeared on the original subject, without understanding the “why” behind the design.
For too long, emerging markets have been content to be the world’s biggest consumer – a strategic liability. The task ahead is to reject that “topological thinking,” stop reproducing the defects of the past, and evolve from a passive market into a technology giver. The future of paints and coatings is smart, green, and autonomous, and the responsibility now is to lead that charge – moving from imitation to invention.
