Concrete

New admixtures are primarily developed with the aim of boosting the sustainability of concrete as a construction material.

These innovations are designed to eliminate any negative factors that may arise and thereby guarantee consistent, high-quality concrete production with a reduced carbon footprint.

The experience gained in polymer development for concrete also inspires pioneering products in dry-mix applications such as mortars, screeds and cementitious flooring.

Waterproofing

In this segment, Sika is concentrating its efforts on waterproofing systems for tunnels and buildings. A particular emphasis is on waterproofing systems for installation before and after concreting as well as technologies that are tailored to the needs of the latest-generation tunnel-boring machines (TBM).

In the year under review, Sika extended and completed the waterproofing system SikaProof® by launching Sikaproof® P and Sikaproof® A HC. The innovative waterproofing system now covers all applications in all markets.

Roofing

In the development of its roof membrane products, Sika is focusing on low-emission liquid applied membranes and new environmentally friendly, solvent-free waterproof membranes. The Sika i-Cure® technology has paved the way for the development of eco-efficient liquid membranes that also offer maximum safety during on-site application. Moreover, solutions combining membranes with adhesives are opening up new, efficient installation techniques. Drawing on its 25-year track record in premium-quality, polyolefin-based roof membranes – Sika Sarnafil T line-, Sika developed and successfully launched Sikaplan T, a cost- and performance-optimized product range.

Flooring

Development work centers on high-performance cementitious and synthetic resin flooring products that offer reliable application while meeting sustainable building requirements, particularly through the achievement of extra-low-emission ratings for high indoor air quality.

Sealing & Bonding

Two new sealants based on aqueous dispersion polymers were developed. The sealants, for both indoor and outdoor use, excel by their high weather resistance and outstanding elastic properties.

Developments in the special jointing segment included sealants for the construction and refurbishment of airport runways and sealants with excellent chemical/acid resistance for silos and biogas tanks.

Refurbishment

Sika is capitalizing on innovative filler technologies to develop new high-performance mortar products with improved workability and a broader scope of application. By replacing cement constituents with various active cementitious aggregates and fillers, Sika has vastly enhanced the sustainability performance of these products. Selection and proportioning of the filler components take account of the locally available raw materials and individual customer needs, in particular enhanced durability and a longer service life of the mortar products.

Industry

Weight reduction through the use of lightweight materials as a means of optimizing the energy efficiency of end products is a key trend in the industrial production of moving parts, automotive engineering and the wind energy sector. Accordingly, the past financial year saw Sika open a Composite Competence Center with the aim of gainfully pooling composite and adhesive technologies, research and development activities, and structural bonding simulations for customers.

Sika solutions also paved the way for new innovations in lightweight automotive construction. Sika’s UHM technology allows the large-area bonding of carbon-fiber-reinforced polymers (CFRP) with aluminum. The new application was first implemented in BMW's i-Series vehicles and proceeded to win a 2015 PACE Award for product innovation, possibly the most important distinction of its kind in the automotive industry. Another prizewinner was the SikaMelt-9185 IA adhesive solution for solar applications, which received recognition from, among others, the Fraunhofer Institute in Freiburg, Germany.
