Sika has agreed to acquire the adhesives business of Japan-based chemical company Resonac Corporation. This strategic move aims to expand Sika's production footprint across Asia and strengthen its access to Japanese automotive original equipment manufacturers.
Why it matters
The acquisition allows Sika to integrate an established regional production network and complementary technology portfolios, driving operational cost synergies. This deal deepens market penetration in Japan, China, and Taiwan, where Resonac maintains core manufacturing and sales sites.
Sika generated CHF 11.20 billion in annual sales in 2025 across its 103-country subsidiary network and 400 existing factories. The deal integrates Resonac Corporation's regional sites to scale operations in Asia.
The players
Sika
A global chemical company focused on the construction and industrial markets with operations in 103 countries.
Resonac Corporation
A Japan-based chemical company that manufactures and supplies various high-performance industrial materials.

The transaction leverages Resonac's local manufacturing and sales presence in Japan, China, and Taiwan to accelerate Sika's automotive sector growth. By combining these technology portfolios, Sika intends to optimize its supply chain and create long-term operational cost synergies. The integration focuses on securing direct pathways to Japanese automotive original equipment manufacturers, enhancing regional delivery capabilities.

Market Landscape
This acquisition aligns with the broader consolidation trend in the global adhesives and sealant market, where major players move to secure regional production capabilities. It reflects Sika's specific strategy of purchasing established regional players to gain immediate, high-barrier market access.
Operators in the industrial adhesive and automotive supply sectors should monitor for potential shifts in regional procurement terms as these two production networks merge. Review your existing supplier contracts to identify any overlaps that may emerge as Sika integrates these new manufacturing sites.
The takeaway
Large-scale acquisitions in the industrial sector are increasingly driven by the need for regional manufacturing nodes rather than just product expansion. Track the mid-2027 closing date to see how the integrated entity reconciles its combined production capacity and pricing power.
