Parker Hannifin’s Performance Materials Division has launched three thermal adhesives in its CoolTherm portfolio for electric-vehicle and industrial electrification applications. The products offer different combinations of bonding, cure time, toughness, rework time, and resistance to sag; pricing, availability, and product performance data beyond the reported specifications were not provided.

Parker Hannifin’s Performance Materials Division has launched three thermal adhesives for its CoolTherm portfolio, targeting electric-vehicle and industrial electrification applications. The products are designed for different bonding and dispensing needs, including faster curing, longer rework time and improved resistance to sag in large beads.

The new materials are CoolTherm UR-2800, CoolTherm UR-2400 SLW and CoolTherm TC-2080. Parker describes UR-2800 as a thermally conductive urethane adhesive designed to bond a wider variety of substrates, deliver higher bond strengths and cure quickly. The announcement does not specify cure times, strength values or the substrates tested.

UR-2400 SLW is a slow-cure thermally conductive urethane adhesive. Parker reports thermal conductivity of about 2.0 W/m·K and describes it as offering moderate-to-high strength, high toughness and an extended window for rework. The source does not give a numerical cure schedule or define the duration of that rework window.

The third product, TC-2080, is a thermally conductive adhesive developed to retain key properties of CoolTherm TC-2002 while removing the need for glass spacers, according to Parker. The company also says TC-2080 is intended for very large dispensed beads and provides increased sag resistance. No test results or direct performance comparison with TC-2002 were included in the announcement.

announcementWhen: Announced October 7, 2026
The developmentParker Hannifin’s Performance Materials Division announced three new CoolTherm thermal adhesives for EV and industrial electrification applications.

Different Adhesives for Assembly Needs

The additions give manufacturers more options for joining components where thermal transfer and mechanical bonding are both relevant. The product descriptions point to distinct production considerations: a quick-cure option, a slower-curing material that allows more time for rework, and an adhesive aimed at large beads and spacer-free assembly.

Those distinctions may matter to engineering and manufacturing teams selecting materials for battery and electrification systems. Cure time can affect assembly pace, while rework time and bead behavior can affect process flexibility. Parker’s announcement identifies these intended characteristics, but does not quantify resulting production gains, reliability improvements or cost effects.

CoolTherm’s Electrification Focus

The launch expands Parker’s existing CoolTherm thermal-management materials portfolio. The company presents the three products as solutions for EV and industrial electrification applications, where manufacturers may need adhesive materials suited to different designs and manufacturing processes.

Parker framed the release around changes in battery architecture and manufacturers’ demand for production-ready materials. The source does not identify particular vehicle programs, customers, facilities or industrial equipment using the new adhesives, and it gives no launch history beyond the October 7 announcement.

“As battery architecture evolves, EV and industrial electrification manufacturers need proven, production-ready thermal adhesive solutions that improve reliability, manufacturability and design flexibility.”

Pricing and Performance Data Missing

The announcement does not state pricing, availability, order timelines or geographic distribution for the three products. It also does not provide detailed test methods, cure schedules, bond-strength figures, or application-specific performance data beyond UR-2400 SLW’s approximate thermal conductivity of 2.0 W/m·K.

It remains unclear how the products compare with earlier CoolTherm formulations under the same test conditions, which substrates Parker used to assess UR-2800, and how much sag resistance TC-2080 adds. Parker’s claims about reliability, manufacturability and design flexibility describe intended benefits; the source does not document measured results or named customer use.

Watch for Product Specifications

Manufacturers evaluating the adhesives will need product data and application guidance to determine which formulation suits their processes. Further specifications from Parker—including cure conditions, substrate compatibility, test results and commercial availability—would clarify how the materials can be used and compared.

The October 7 report does not identify a later launch event, release schedule or customer program. No additional milestone was announced in the source material, so the next confirmed development would be further information from Parker or evidence of deployment in specific applications.

Key Questions

What did Parker Hannifin announce?

Parker’s Performance Materials Division launched three CoolTherm thermal adhesives for EV and industrial electrification applications: UR-2800, UR-2400 SLW and TC-2080.

What is the reported thermal conductivity of UR-2400 SLW?

Parker reports approximately 2.0 W/m·K for UR-2400 SLW. The announcement does not provide a test method or additional conductivity figures for the other two products.

How do the three adhesives differ?

Parker describes UR-2800 as a quick-cure urethane designed for broader substrate bonding and higher bond strength; UR-2400 SLW as a slower-curing, tougher urethane with extended rework time; and TC-2080 as an adhesive for large dispensed beads that removes glass spacers and increases sag resistance.

Are prices or availability dates confirmed?

No. The source announcement does not give pricing, availability dates or order details for the new adhesives.

Has Parker provided independent test results or named customers?

The report does not include independent test results or name customers using the products. Parker’s descriptions of intended performance and applications are company statements.
