Finorchem’s Tackifying Resins: The Science Behind Advanced Adhesion, Performance And Sustainability
- By TT News
- July 07, 2025
Tackifying resins or tackifiers are versatile organic substances with low molecular weight, high glass transition temperature and a softening temperature above room temperature. They exist as solid materials, derived from certain trees or chemically synthesised. Tackifiers can be broadly classified as natural (rosin-based and terpene-based) and synthetic (C5 & C9 based aliphatic or aromatic hydrocarbon and coumarone-indene) and, finally, phenol-formaldehyde condensation resins.
Phenolic tackifiers enhance adhesion by promoting superior surface contact and intermolecular interactions with rubber substrates, ensuring high initial tack and long-term retention. Unlike general tackifiers that rely primarily on weak Van der Waals forces, phenolic resins offer exceptional cohesion, heat resistance and humidity stability, making them ideal for demanding applications. Their low loading levels minimise heat build-up, optimising processing efficiency while preserving physical, dynamic and rheological properties. Additionally, phenolic tackifiers demonstrate remarkable stability and environmental compatibility, ensuring consistent performance without compromising formulation integrity. This balance of adhesion strength, thermal durability and sustainability makes them a preferred choice in rubber compounding.
Para-tertiary octyl phenol formaldehyde (PTOP) resin is a high-performance phenol-formaldehyde resin, widely utilised in rubber applications, coatings and adhesives as an industrial tackifier. PTOP resins are preferred tackifiers due to their ideal molecular weight, polarity and superior compatibility with rubber matrices, ensuring strong adhesion through hydrophobic interactions. Their octyl chain length facilitates optimal softening, enhancing wetting, green strength and cohesion.

The effectiveness of these resins is influenced by fillers that reduce tack, while PTOP enhances tack through improved interfacial bonding. Excessive oil incorporation can diminish tack by disrupting resin-rubber interactions. Balancing superior adhesion, thermal stability and process efficiency, PTOP resins remain indispensable in demanding industrial formulations.

Zeon Corporation has finalised the construction of a new bench-scale facility at its Tokuyama Plant in Shunan City, Yamaguchi Prefecture, dedicated to advancing the efficient production of butadiene from sustainable ethanol sources. The project, which broke ground in July 2025, represents a strategic move to establish a naphtha-independent raw material supply chain, thereby bolstering both corporate sustainability and the broader transition towards a carbon-neutral society. The facility is slated to commence full-scale operations in January 2027, with the ultimate goal of achieving commercial viability by 2034.
A commemorative ceremony took place at the plant site on 31 July 2026, drawing a total of 46 attendees. The gathering included official representatives from Japan’s Ministry of Economy, Trade and Industry (METI), the New Energy and Industrial Technology Development Organization (NEDO) and local governmental bodies from Yamaguchi Prefecture and Shunan City. Also present were delegates from the Yokohama Rubber Company, the construction contractor and various affiliated firms, alongside Zeon’s leadership, including Akira Honma, the Corporate Officer and Tokuyama Plant Manager.
This initiative forms one half of a dual-themed research and development programme undertaken in partnership with Yokohama Rubber, under the auspices of NEDO’s Green Innovation Fund. The collaborative effort is focused on the social implementation of technologies for synthesising both butadiene and isoprene from renewable biological materials by the 2030s. As part of this process, Zeon is set to produce a prototype polybutadiene rubber using the output from the new bench-scale facility, while Yokohama Rubber will subsequently manufacture test tyres from this material and conduct performance evaluations on test tracks.
Both companies have outlined a clear roadmap, intending to finalise the core technology for societal deployment by 2030 through the operation of a larger pilot plant, with full-scale commercialisation targeted for 2034. The bench-scale facility is a critical precursor in this phased approach, providing essential data for the scale-up process.
The broader project encompasses two selected NEDO themes, both subsidised through the Green Innovation Fund. The first involves the highly efficient synthesis of butadiene from ethanol, with technical cooperation from the National Institute of Advanced Industrial Science and Technology. The second focuses on biotechnological pathways to directly produce butadiene and isoprene from plant-based materials, involving partnerships with the Institute of Science Tokyo and RIKEN. Both tracks aim to supplement synthetic rubber feedstocks and support closed-loop recycling, aligning with Japan’s 2050 net-zero emissions goal by fostering long-term industrial innovation.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly Natural Rubber Statistical Report for June 2026, a month defined by price resilience amid conflicting market forces. The provisional reopening of the Strait of Hormuz triggered a sharp 20.29 percent drop in Brent crude oil prices to USD 85.40 per barrel. However, this bearish signal was counterbalanced by persistent supply constraints from El Niño-related weather disruptions across major producing regions.
Physical rubber prices posted broad-based gains across most grades. SMR-20 rose 1.39 percent to USD 2.32 per kilogramme, while STR-20 gained 2.61 percent to USD 2.55 per kilogramme. RSS-3 and RSS-4 advanced 4.98 percent and 5.88 percent to USD 3.09 and USD 2.84 per kilogramme, respectively, though latex eased 1.44 percent to USD 1.94 per kilogramme. On the trade front, China's imports surged 7.14 percent month-on-month, while India and Viet Nam declined. Export growth was recorded for Cambodia, Viet Nam and Indonesia, though Thai shipments contracted.

Global production for 2026 is projected at 15.310 million tonnes, up 2.3 percent from 2025, driven by gains in Thailand, China, India and Malaysia. However, June output fell 3.7 percent year-on-year to 1.207 million tonnes due to seasonal wintering and El Niño-related weather disruptions. Malaysia, Indonesia and Cambodia have introduced new incentive and governance measures to strengthen their sectors. Global consumption is forecast to grow 0.7 percent to 15.411 million tonnes in 2026, with June consumption rising 3.3 percent to 1.300 million tonnes, led by China and India amid steady tyre and EV-related demand.
Currency markets saw the Malaysian ringgit trade between RM3.96 and RM4.08 against the US dollar, while the Thai baht ranged from 32.56 to 33.24. In futures trading, the SHFE September 2026 contract averaged 17,580.68 CNY per tonne, down 0.45 percent month-on-month, while the SGX September contract averaged USD 2.24 per kilogramme, up 1.75 percent, with both reflecting tightening supply and firm downstream demand.
