Joint Sealing Elastic Adhesive Bonding

Purform® - The Leading Polyurethane Technology

Polyurethanes are the leading technology for sealants, adhesives and flooring, and for good reason. For most specifications, polyurethane adhesives, sealants and floor products outperform other technologies such as SMPs and silicones. Sustainable and long-lasting sealing, bonding and flooring combines multiple aspects, ranging from application properties to mechanical properties and resistance to environmental impact. On the whole, polyurethanes are the technology proven to best meet your requirements, as they offer the best balance.

With Purform®, Sika has developed a new technology that increases the performance of adhesives, sealants and floor systems. Sikaflex®, Sikabond® and SikaTack® Purform® adhesives and sealants and Purform®  Sikafloor® floor products have an ultra-low free monomeric diisocyanate content, in addition to their other product-specific advantages. Users of the Purform® technology benefit from the unique performance of polyurethane, whilst eliminating the need for specific REACH health and safety trainings. Users' exposure to chemicals is thus reduced and limited to an absolute minimum.

Proven Performance Overall

Icon Strenght


Only polyurethanes can meet high strength and modulus specifications as required in the automotive industry.

Icon Flexibility


Polyurethanes provide higher elongation at low stress and a better recovery rate than SMP solutions. They are indispensable for long-lasting building envelope waterproofing.

Icon Durability


Polyurethanes have excellent resistance to environmental impacts such as humidity, chemicals, and mechanical impacts, and can be formulated to be highly resistant to UV weathering.

Icon Sustainability


Increased durability by preventing leaking joints, altered substrates and debonding from staining and cracking.*

Icon Work Safety

Work Safety

Sealants and adhesives are hazard label-free.* Workers are less exposed to chemicals, and no safety training is required.

Purform® - Making Good Better

Purform® is Pure

Purform® pre-polymers enable the production of products with high performance that are also label-free* and consequently reduce user exposure to an absolute minimum.

Unlike silicones or SMP products, there are no emissions of critical materials such as methanol while curing.

Purform® is Polyurethane

Purform® is a high performance polyurethane. The unique combination of hard and soft segments in its polymers create high-strength adhesives, ideal for use in the automotive industry, as well as highly
flexible sealants that can be tailored for construction.In both cases, products are more durable and long-lasting, even in harsh environments.

Purform® is Performance

By manufacturing its own pre-polymers, Sika can design products to meet specific requirements, such as non-staining, non-cracking or non-yellowing sealants as well as direct adhesion to specific substrates.

With Purform®, Sika is reinventing polyurethane—so good technology is becoming even better. Sika’s full control of production from the pre-polymer to the final composition allows for unique combinations of features in our Sikaflex® and SikaTack® adhesives and sealants as well as Sikafloor® floor products. This is why Sika’s Purform® technology is able to overcome the common limitations of adhesives, sealants and polyurethane flooring.

Purform® further enhances the performance of polyurethane solutions for sealing, bonding, flooring and protection, while eliminating unwelcome monomeric components from our products. With Purform®, you benefit from the unique advantages of polyurethanes, minimal exposure to monomers, and there is no need for specific REACH health and safety training.

Purform® adhesives, sealants and flooring products combine the best mechanical performance with excellent adhesion to a wide range of materials, superior durability even in harsh environments, and top-class UV resistance. When compared to alternative flooring, sealant and adhesive technologies such as silane modified polymers (SMP), silicones, acrylic dispersions or polysulfides, polyurethanes are better at balancing the different aspects of your specifications and needs.
