To Strive Forward No Energy Waste
From silicone-based protectants to multi-surface aerosol formulas, our detailing lineup delivers lasting protection and a pristine finish for every new car interior.
Silicone spray is a versatile, multi-surface aerosol product formulated with polydimethylsiloxane (PDMS) or related silicone polymers. When applied to new car interior surfaces, it creates an ultra-thin, invisible protective film that simultaneously lubricates, repels moisture, prevents UV-induced fading, and restores a factory-fresh appearance. Unlike traditional wax-based products, silicone spray bonds at a molecular level with plastics, rubber, vinyl, leather, and fabric — making it the go-to solution for professional detailers and everyday car owners alike.
For brand-new vehicles, the interior is particularly vulnerable in the first 12 months. Untreated dashboards, door panels, and seat surfaces are exposed to intense UV radiation, heat cycling, and contact abrasion. A high-quality silicone spray applied early in a vehicle's life can extend the visual and functional lifespan of interior materials by 3–5 years, dramatically preserving resale value.
A single application provides up to 3 months of continuous protection on dashboards, door trims, and center consoles.
Integrated UV absorbers prevent photodegradation of plastics and leathers, maintaining original color depth and texture.
Water, coffee spills, and liquid contaminants bead up and wipe away cleanly — no staining, no residue.
Effective from -40°C to +200°C, ensuring consistent performance in both arctic winters and desert summers.
Eliminates static electricity on instrument panels and screens, dramatically reducing dust accumulation between cleans.
Low-VOC, water-based silicone formulas comply with REACH and EPA standards — safe for occupants and the environment.
The global automotive care and detailing market was valued at approximately USD 11.2 billion in 2023 and is projected to reach USD 18.6 billion by 2030, growing at a CAGR of 7.4%. Within this segment, aerosol-based silicone spray products account for a significant and rapidly expanding share, driven by rising vehicle ownership in Asia-Pacific, increasing consumer awareness of paint and interior protection, and the booming professional detailing services industry.
China, as the world's largest automobile market with over 30 million new vehicles sold annually, represents the single biggest growth opportunity for silicone spray manufacturers. Domestic OEM detailing kit bundling — where silicone interior sprays are included in new car delivery packages — is now standard practice among premium brands like BYD, Li Auto, and NIO. This trend has catalyzed a surge in demand for high-performance, low-odor, and environmentally compliant silicone aerosol formulations.
In North America and Europe, the professional detailing sector is the primary demand driver. Mobile detailing businesses, car dealership service centers, and automotive reconditioning shops collectively consume millions of units of silicone spray annually. The shift toward ceramic-infused silicone sprays — combining traditional silicone protection with SiO₂ nano-ceramic bonding — represents the most significant product innovation in the past five years.
The dashboard is the most UV-exposed surface in any vehicle interior. A light, even application of silicone spray every 60–90 days creates a durable protective layer that prevents the characteristic "cracking" and "chalking" seen on neglected dashboards. For new vehicles, apply within the first two weeks of ownership to establish baseline protection before any UV damage occurs. Always use a low-gloss formula on dashboards to prevent distracting reflections on the windshield.
New car door seals and window gaskets are particularly susceptible to ozone degradation and compression set. Silicone spray acts as both a conditioner and a protectant — keeping rubber supple, preventing squeaking, and extending seal lifespan by up to 40%. Professional detailers apply silicone spray to all rubber contact points as a standard part of new vehicle delivery preparation.
While dedicated leather conditioners remain the primary choice for full leather upholstery, silicone spray is ideal for vinyl-leather hybrid materials and PU synthetic leathers increasingly used in modern EVs and budget vehicles. The spray penetrates surface micro-pores to prevent cracking while simultaneously repelling liquid spills — a dual-action benefit unavailable in traditional conditioners.
Piano-black and gloss-finished trim panels — ubiquitous in modern vehicles — are notorious scratch and fingerprint magnets. Silicone spray applied to these surfaces creates a sacrificial protective layer that absorbs light scratches and dramatically reduces fingerprint visibility. The anti-static effect also keeps these surfaces dust-free for weeks between applications.
Beyond the interior, silicone spray finds extensive use on exterior plastic trim, engine bay plastic covers, and under-hood rubber components. The high-temperature stability of silicone makes it ideal for engine compartment applications where conventional products would degrade rapidly.
Electric vehicles introduce new interior material challenges — larger touchscreen surfaces, sustainable/recycled material panels, and minimalist interior designs with exposed surfaces. Silicone spray formulations specifically engineered for EV interiors must be screen-safe, anti-static (critical for capacitive touch surfaces), and free from solvents that could damage sustainable bio-based materials. This represents one of the fastest-growing niche segments in the automotive aerosol market.
The fusion of SiO₂ nano-ceramic particles with traditional silicone polymers creates a semi-permanent protective coating that bonds chemically to surfaces. These hybrid products offer 6–12 months of protection per application and are rapidly displacing traditional silicone sprays in the premium detailing segment.
Growing environmental regulations and consumer sustainability demands are driving R&D into bio-derived silicone alternatives. Water-based, low-VOC, and biodegradable silicone spray formulations are gaining market share, particularly in European markets with stringent chemical regulations.
Leading aerosol manufacturers are deploying machine learning algorithms to accelerate formula optimization — reducing development cycles from months to days. AI-driven analysis of surface chemistry data enables precise customization of silicone molecular weight and crosslink density for specific substrate types.
Next-generation aerosol packaging integrates precision valve technology for consistent, fine-mist application that minimizes product waste and overspray. QR-coded packaging provides users with substrate-specific application guides via smartphone — enhancing user experience and professional outcomes.
Automotive manufacturers are increasingly partnering with aerosol chemical companies to apply silicone-based interior protectants at the factory level. This "born protected" approach is particularly prevalent in the EV sector, where interior material longevity is a key differentiator.
China's aerosol manufacturing ecosystem — combining advanced R&D capabilities, cost-competitive production, and massive domestic market demand — is positioning Chinese manufacturers as global leaders in silicone spray innovation and export. Facilities like Depur's Nanxiong base exemplify this industrial evolution.
