Discover Purform® Solutions for Construction

Where is your building most vulnerable to water ingress? At the joints!

In construction, sealants, adhesives and floors only amount to a small fraction of the total expenses, but their failure can result in very costly repairs. Robustness, reliability and durability are key properties of a sealant, adhesive or floor system. Every construction site is different. The skill of the workforce, the joint dimensions and their preparation, the substrates and their quality and the climatic conditions all vary widely, even from day to day.Our novel Sika Purform® sealants, adhesives and floor products build on our long-standing expertise in construction and offer state-of-the-art, high-performance polyurethane.

What is Polyurethane?

Polyurethane is the first choice for demanding, high-performance bonding, sealing and flooring applications. Only polyurethane can provide the strength, flexibility and/or durability needed by our customers in construction and industry. The superiority of polyurethane technology originates from its underlying unique microstructure of flexible and hard phases, which can be adjusted according to requirements.

Sika has always been an innovation driver in polyurethane technology. Recent innovations include bubble-free curing with latent hardeners in 1-component systems, Powerflex or the instant curing technology in 2-component systems. In 2020, we launched our big innovation in polyurethane - Purform®.   

What is Purform®?

Purform® is the technology brand of our new polyurethane platform and is a composition of the words “Pure”, “Polyurethane” and “Performance”. Purform® starts at the very roots of polyurethane and gives us the control to engineer perfect and pure pre-polymers. These new building blocks are the core of the new products with an ultra-low free monomeric diisocyanate content.

Purform® polyurethane, through its simplicity, perfection and purity, gives our engineers the scope to develop products with the performance you need to meet the challenges of tomorrow, such as durable sealants, adhesives and flooring products that help save energy, lower fuel consumption, and are safe to apply.

What is Sikaflex®?

Sikaflex® is a synonym for high quality and performance sealants and adhesives for construction, industry and the automotive sector. With a 50-year legacy, global presence, and countless applications and references, Sikaflex® is the Sika brand for quality products based on polyurethane and modified polyurethane.

What is Sika ComfortFloor®?

Sika ComfortFloor® is a seamless, fluid-applied floor system engineered to be ergonomic, hygienic, comfortable and easy to clean. These decorative flooring systems are for interior concrete surfaces and are ideal for commercial, residential, educational and healthcare buildings.

With Purform® technology, the highest grade Sika ComfortFloor® PS-24 and Sika ComfortFloor® Marble FX systems have been slightly adjusted to consequently reduce user exposure to an absolute minimum. The performance and outstanding look are proven, as they have been used for years in countless projects globally and could even be improved further.

For Architects & Specifiers

In modern project design, specification and construction are not often undertaken at the same place. For example, the architecture and specification team may be based in Boston, while the building is located in Berlin, Germany. The building must meet the highest Green Building Standards, and may include prefabricated elements imported from the UK, façade cladding with stone from Brazil, a glass curtain wall from Spain, etc. For such complex constructions, it is beneficial to have a reliable partner that is globally active, can offer solutions from the basement to the roof, provides local support and has products that are globally available and have a high level of certification and references.

Sika is just such a partner, and Purform® is our latest generation of adhesives, sealants and floor products for durable waterproofing and decorative flooring.
