The assumption that Sika’s construction chemicals R&D is still centered on conventional sealants and cement additives is no longer accurate. Its 2026 patent activity shows the strongest concentration in adhesion technology, with 48 patents, followed by automotive applications with 40 patents, cementitious systems with 35 patents, waterproofing and sealing with 29 patents, and polyurethane systems with 27 patents. That is not a broad formulation spread. It signals where bonding, sealing, and repair performance are being re-engineered for more demanding construction and mobility environments.
The gap is clear. Contractors need materials that bond to difficult substrates, tolerate incomplete surface preparation, cure in cold or damp conditions, and remain workable long enough on site without delaying strength development. Automakers need adhesives, reinforcements, and insulation systems that support lightweighting, corrosion protection, EV thermal and acoustic requirements, and automated assembly.
We analyzed Sika’s 2026 patent activity to identify where R&D is concentrating, which technologies are maturing, where emerging bets are forming. Let’s dive in.
What’s Inside the Report?
Why adhesion technology is Sika’s largest innovation focus:
Sika is advancing adhesion systems for difficult substrates, residual adhesive beads, contaminated surfaces, pre-fix and bonding systems, and coatings that enable permanent bonding with fresh concrete. This supports both automotive lightweighting and construction bonding needs.
How automotive applications are shaping Sika’s materials strategy:
Sika’s automotive-focused innovations target body-in-white reinforcement, corrosion protection, NVH control, thermal insulation, EV acoustic requirements, and automated application systems.
Why cementitious systems are linked to low-carbon construction:
Sika is developing cementitious systems for alkali-activated binders, crack repair, waterproof strips, and secondary hydration-based repair methods. These areas align with infrastructure rehabilitation and lower-CO₂ binder adoption.
How waterproofing and sealing remain core growth areas:
Sika’s waterproofing and sealing work focuses on roof membranes, two-component top coats, high-solids coatings, UV-stable polyurethane systems, low-VOC compliance, and lightweight pumpable materials.
Why polyurethane innovation is focused on workability and cure control:
Sika is improving polyurethane systems through pot life extension, blocked polyamine hardeners, low-modulus sealants, rapid cure, reduced tack, and raw material cost management.

Key Signals You Can’t Ignore
Sika is deepening its automotive penetration:
The 40 automotive-related patents show serious OEM engagement. The focus on structural adhesives, hollow-section reinforcement, corrosion protection, and automated mounting systems suggests Sika is positioning itself for high-volume EV and lightweight vehicle production.
Adhesion is becoming a platform advantage:
The largest cluster is not general adhesives. It targets difficult real-world bonding conditions, such as contaminated surfaces, residual adhesive beads, fresh concrete, and repair scenarios where perfect surface preparation is not possible.
Cementitious innovation is tied to sustainability and infrastructure repair:
Dispersants for alkali-activated binders and secondary hydration-based crack repair show how Sika is aligning with low-carbon concrete and repair-over-replacement economics.
Workability is becoming as important as cured performance:
Several patents focus on longer pot life, low-temperature cure, overpaintability, tack reduction, and simplified installation. The pattern is clear: Sika is making the chemistry more complex so contractors and OEMs get easier, more reliable application.
Low-temperature cure could extend the construction season:
The report identifies 6 patents in low-temperature cure systems. These technologies can support cold-climate installation, reduce heating needs, and help contractors work across more months of the year.
Additive manufacturing is still early but worth monitoring:
With 4 patents, additive manufacturing remains a small direction, but Sika’s work in extrusion materials for roofing components and custom parts suggests early exploration of site-specific or low-volume construction products.
