Targeted organosilicone chemistry and petroleum resins optimized for high temperature, tropical humidity, and salt-spray resistance in South Asian industrial clusters.
Essential thermoplastic resin for high-performance adhesives, hot-melt road marking paints, and compound rubber tackifiers utilized in Colombo infrastructure projects.
Long-chain alkyl silane providing deep-penetrating water repellency for coastal concrete protection and inorganic filler dispersion in industrial coatings.
Highly reactive alkoxysilane used for surface modification of silica and minerals, enhancing structural adhesion in moisture-curing sealants.
Bifunctional organosilane providing robust adhesion promotion in epoxy packaging, electronics encapsulation, and industrial fiberglass coatings.
Sri Lanka’s manufacturing sector is undergoing an advanced material transition. High-value exports, particularly Ceylon natural rubber products, performance textiles, and heavy civil infrastructure (including port city expansions), demand top-tier chemical additives to meet rigorous global standards.
Organosilicon plays a pivotal role in this modernization. As natural rubber is processed into engineered items like industrial solid tires, conveyor belts, and automotive components, our silane coupling agents ensure superior phase adhesion between silica fillers and the polymer matrix. This significantly reduces rolling resistance and heat build-up under Sri Lanka's high ambient operating temperatures.
In the textile sector—centered around Colombo and Gampaha—finishing agents derived from specialized functional silicone oils impart durable water repellency, premium softness, and breathability to exported garments. This enables local apparel manufacturers to supply Tier-1 global fashion brands with compliant, performance-focused products.
Founded in 2012, Shandong Boctok Chemical Co. serves as a premier marketing, sales, and technical service center for Boctok™ domestic and overseas business operations. In 2023, our strategic market outreach realized a global sales volume of US$280 million. While the BOCTOK brand initially built a strong reputation serving the Russian market, we have expanded our robust supply chain networks and engineering partnerships to support growing industrial sectors throughout South Asia, notably Sri Lanka.
Our core organosilicone business spans twelve specialized series of silane coupling agents and crosslinkers. This comprehensive portfolio includes aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane formulations. Additionally, we manufacture high-performance silicone oils (dimethicone, high-hydrogen silicone oil, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil, OH polymer, and alkoxy silicone oil), MQ resins, and room-temperature vulcanized (RTV) silicone rubbers. These chemical systems improve durability and properties in glass fiber, wind energy, electronics, coatings, and adhesives.
To support global supply needs, we recently invested US$65 million to establish a state-of-the-art facility in the Bohai Industrial Park, a certified provincial chemical zone in Shouguang City, Shandong Province. The new plant features 6 automated DCS production lines, expanding our annual output of silane coupling agents by 30,000 tons. This production is supported by modern Safety Instrument Systems (SIS) and run under strict ISO9001 quality management parameters to ensure stable material batches.
Boctok’s Tier II core business is focused on petroleum resins. We have invested in a leading hydrocarbon resin manufacturing joint venture in China. Operating three modern production facilities in Zibo, Fushun, and Nanjing, we utilize raw material streams from SINOPEC and PetroChina. Supported by advanced polymerization technology, our hydrocarbon resins are used globally by major industrial manufacturers, including Fortune 500 enterprises. Our portfolio features C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 resins, C9 hydrocarbon resins, dicyclopentadiene (DCPD), and methyl cyclopentadiene dimer.
Boctok also serves the agricultural sector by manufacturing key chemical intermediates and raw materials. These materials are used to formulate pesticides, fungicides, insecticides, seed treatments, herbicides, and plant growth regulators. For Sri Lanka’s agricultural economy, these chemical systems provide reliable options for crop protection and yield improvement.
