In the heavy industrial, automotive, and infrastructure maintenance sectors, pitch cleaners and tar removers serve as critical maintenance compounds. Pitch, which comprises highly complex, high-molecular-weight hydrocarbons, including bitumen, asphalt, and natural tree saps, poses a significant cleaning challenge. Traditional aqueous cleaners fail to break the cohesive bonds of these hydrophobic matrices, necessitating specialized organic solvent formulations.
Globally, the market demands high-solvency formulations that can balance cleaning efficiency with substrate preservation. Commercial applications extend beyond personal automotive detailing to large-scale fleet operations, asphalt construction maintenance, road marking remediation, and public infrastructure cleaning. As regulatory pressures on volatile organic compounds (VOCs) increase globally, the industrial landscape is shifting toward safer, high-flashpoint, emulsifiable solvents that satisfy both EHS (Environment, Health, and Safety) protocols and strict performance thresholds.
Modern pitch and tar removal mechanisms rely on the principle of "like dissolves like." High-efficiency formulations utilize a blend of aliphatic hydrocarbons, terpene-based solvents (such as d-limonene), and non-ionic surfactants. This unique combination works via sequential action:
By leveraging optimized Chinese chemical manufacturing clusters, exporters are able to source these advanced propellant and solvent components locally, minimizing the raw material markup and passing the cost-benefit down to global B2B procurement partners.
China's dominance in the chemical aerosol sector is driven by highly integrated supply chain ecosystems. Linyi, Shandong, has emerged as a premier cluster for fine chemical and aerosol production. This concentration offers several structural advantages:
Vertical Raw Material Integration: Factories operating in this region enjoy immediate access to petroleum refineries, tinplate packaging manufacturers, gas propellants (LPG, DME), and valve assemblies. This reduces transport costs and keeps the supply chain extremely resilient to external shocks.
Advanced Production Automation: Leveraging 10+ international standard automated filling lines ensures that high-speed production (up to tens of thousands of cans per shift) maintains absolute consistency in propellant pressure, active ingredient volume, and leak-proof sealing.
We provide one-stop, highly adaptable OEM/ODM custom manufacturing services matching global brand demands.

Aerosols are classified under United Nations dangerous goods categories (UN1950, Class 2.1 or 2.2). As a result, global procurement is not merely an exercise in finding the lowest production price, but in establishing a highly compliant transport supply chain. The lack of proper packaging licenses can result in customs seizures and shipping lines refusing cargo.
Linyi Xingguan and Shandong ClanZhao hold specialized government-issued certifications for dangerous goods packaging and chemical manufacturing license. This qualification verifies that every export container we package is built, labeled, and braced according to strict maritime shipping rules. Our strategic partnerships with international freight forwarders specialized in dangerous goods ensure reliable container booking, smooth customs transit, and safety-verified delivery to ports across North America, Europe, the Middle East, and Latin America.
Our quality assurance framework spans the entire lifecycle of chemical synthesis and mechanical filling. We operate on a dual-track quality protocol:
100,000 square meters of production base, 10 fully automated filling lines, and comprehensive quality control equipment.
ISO9001 quality management system certification, chemical production licensing, and dangerous packaging compliance certifications.
Heavy duty removal of road tar, asphalt debris, and tree sap from exterior body finishes. Designed to liquefy stubborn residues in seconds without degrading clear coats or leaving behind abrasive surface scratches.
Highly effective cleaning agents for commercial asphalt laying vehicles, hand tools, municipal signage, and post-construction cleaning where heavy bitumen over-spray requires rapid solvent solubilization.
Engineered for chemical solvent washing systems and direct spray maintenance on manufacturing equipment exposed to heavy greases, resinous glues, and carbon deposits.
The contemporary procurement landscape is experiencing high pressure to conform with sustainability metrics. Buyers in regions such as the EU and North America are transitioning toward aerosols powered by eco-friendly propellants with low global warming potential (GWP) and carbon-neutral hydrocarbon blends. At the same time, B2B distributors are actively seeking stable supply lines in China that can assure multi-year contract pricing, mitigating energy and feedstock inflation.
Through close integration with domestic petrochemical refineries, Shandong ClanZhao can hedge raw material costs, enabling global buyers to maintain stable margins on wholesale brands. Furthermore, customizable formula concentrations allow brands to fine-tune the solvent ratio to precisely align with local environmental laws without sacrificing cleaning performance.
Direct insights addressing B2B chemical safety, formula compatibility, logistics, and OEM processes.
Our pitch cleaners are composed of high-purity aliphatic hydrocarbons blended with bio-based terpene solvents (such as d-limonene) and non-ionic surfactants. This ensures fast dissolution of complex asphalt structures while remaining safe for standard clear coats, plastics, and glass when used as directed.
We are a certified exporter of dangerous goods packaging, compliant with UN1950 regulations. All containers undergo water-bath pressure testing. We prepare full GHS-compliant SDS documentation in multiple languages, coordinate with Class 2.1 shipping lines, and supply the necessary dangerous goods container declarations for hassle-free customs clearance.
Yes. Our R&D laboratory specializes in modifying active solvent concentration ratios. We can formulate low-VOC, high-flashpoint mixtures that fully comply with US state-level CARB guidelines and European Union chemical directives without compromising cleaning efficiency.
For custom OEM/ODM brands requiring customized lithographed can printing, the standard MOQ typically ranges from 20,000 to 30,000 units. This limit is set by the automated tinplate printing line setups. Smaller test runs may be accommodated using labeled cans under specific agreements.
Every single aerosol can passes through an automated inline high-temperature water bath test (approaching 50-55°C). Cans showing any micro-bubbling or pressure drop are rejected by automated sensors. We also run regular torque tests on valves and spray nozzles to maintain consistent aerosol dispersion patterns.
Under recommended storage conditions (cool, dry, ventilated warehouse space, below 45°C), our products offer a stable shelf life of 2 to 3 years. The internal lacquer lining of our tinplate cans protects the metal container from corrosive chemical reactions with the active solution.
