For SIWAY, 2026 has been more than a year of business activities. It has been another step in a long-term journey: building reliable products, strengthening manufacturing capabilities and creating more value for customers around the world.
More Than 40 Years of Sealant Expertise
SIWAY's story began in 1984 with a clear focus on sealants and construction applications.
Over the past four decades, the industry has changed significantly. Building technologies have evolved, architectural designs have become more sophisticated, environmental requirements have become increasingly important, and customers now expect suppliers to provide more than standard products.
SIWAY has continued to develop alongside these changes.
Our experience covers a broad range of sealing and bonding technologies, including:
- Silicone sealants
- Polyurethane sealants
- MS polymer adhesives and sealants
- Polysulfide sealants
- Epoxy anchoring systems
- PU foams
- Waterproofing materials
- Specialized bonding solutions
This breadth allows SIWAY to approach sealing requirements from an application perspective rather than treating every project as a one-product solution.
From Products to Application Solutions
Whether the requirement involves a glass curtain wall, insulated glass unit, window and door system, construction joint, expansion joint, automotive application or industrial bonding project, material selection depends on the substrate, movement, environmental exposure, curing requirements and expected service life.
That is why SIWAY continues to develop application-oriented product solutions designed around real project requirements.
Expanding Our Product Portfolio
One of the defining characteristics of SIWAY's development has been the continuous expansion of its product portfolio.

- General-purpose bonding and sealing
The objective is not simply to increase the number of products, but to provide customers with more technology and application options within a single supply chain.
Engineering Solutions Beyond Standard Products
A modern sealant manufacturer needs to do more than produce cartridges.
Different projects can require different formulations, colors, packaging formats, curing characteristics, adhesion performance and application methods.
For this reason, customization remains an important part of SIWAY's business model.
SIWAY Customization Capabilities
Depending on project requirements, SIWAY can support:
- ☑ OEM and private-label production
- ☑ Customized formulations
- ☑ Customized colors
- ☑ Customized packaging
- ☑ Sample-based product development
- ☑ Application-specific solutions
- ☑ Technical documentation
- ☑ Product selection support
- ☑ Project-oriented technical communication
This capability is particularly relevant for importers, distributors, construction-material companies and established brands looking for a manufacturing partner rather than a simple product reseller.
Engineering Starts With the Application
A structural glazing project, for example, requires a different performance profile from an expansion joint, an automotive windshield or an interior decoration application.
Understanding this distinction is central to SIWAY's product-development approach.
Our goal is to help customers select the appropriate chemistry and product architecture according to the actual application — rather than assuming that one sealant can solve every sealing problem.
Manufacturing Capability: From Raw Materials to Finished Products
Behind every sealant product is a manufacturing system.
For SIWAY, manufacturing capability is closely connected with product consistency, quality control, delivery reliability and long-term customer relationships.
Our manufacturing process is supported by quality-management procedures covering different stages of production, from incoming raw materials and formulation to filling, packaging and finished-product inspection.
Quality Is More Than a Certificate
Certifications and standards are important references, but consistent manufacturing performance also depends on process control and inspection.
SIWAY continues to focus on:
- ✔ Raw-material control
- ✔ Production-process management
- ✔ Finished-product inspection
- ✔ Packaging quality
- ✔ Product traceability
- ✔ Technical documentation
- ✔ Customer-specific requirements
For international buyers, these details matter because product consistency is directly connected with installation performance, project quality and supply-chain reliability.
OEM, Private Label and Customized Supply
Global buyers increasingly need suppliers that can adapt to their own markets.
- ● A distributor may require a specific cartridge design.
- ● A construction-material company may need a private-label product.
- ● An established brand may require a customized formulation or packaging specification.
SIWAY supports these requirements through its OEM and customized manufacturing capabilities.
From Product Concept to Finished Packaging
Depending on the project, cooperation can involve:
This integrated approach allows customers to work with one manufacturing partner across multiple stages of the product-development and supply process.
For long-term B2B relationships, the value of a supplier is not determined only by the price of a single cartridge. Consistency, communication, technical support, customization and delivery reliability are equally important.
Connecting With Customers and the Global Industry
2026 has also been a year of direct communication with customers, distributors, contractors, engineers and industry professionals.
For SIWAY, exhibitions remain an important opportunity to understand what customers are actually looking for.
Face-to-face discussions often reveal requirements that cannot be fully understood through product specifications alone.
Customers may be looking for:
- Better weather resistance
- Higher movement capability
- Faster curing
- Improved adhesion
- More application-specific solutions
- Customized packaging
- Stable long-term supply
- OEM and private-label manufacturing
- Technical support for specific projects
These conversations provide valuable feedback for product development and market expansion.

Four Markets, One Global Direction
From Riyadh to Moscow, Algiers back to shanghai, SIWAY's 2026 exhibition activities reflect a broader strategy:
Stay close to the market, understand regional requirements and build long-term customer relationships.
Different regions have different climates, construction practices, standards and purchasing requirements.
A global sealant manufacturer therefore needs both standardized manufacturing capabilities and the flexibility to respond to local application needs.
What We Learned From the Market in 2026
The construction and sealant industries continue to evolve.
Based on customer conversations, exhibition discussions and developments across the industry, several themes have become increasingly important.
Performance Matters More Than Product Names
Customers are increasingly focused on actual application performance rather than simply choosing a generic category such as "silicone" or "PU."
Questions increasingly center on:
- ✓ Where will the product be used?
- ✓ What substrates are involved?
- ✓ How much movement is expected?
- ✓ What environmental conditions will it face?
- ✓ What curing system is appropriate?
- ✓ What service life is required?
This reinforces the importance of application-based product selection.
Customization Is Becoming More Important
Different markets have different packaging, color, performance and compliance requirements.
OEM and private-label manufacturing therefore remain important parts of international B2B sourcing.
Supply Reliability Is Part of Product Value
For large projects and long-term distribution, a high-performance product is only one part of the equation.
Customers also need:
Consistent quality + stable production + reliable delivery + technical support + responsive communication.
This is why SIWAY continues to view manufacturing and service capabilities as an integral part of product value.
Sustainability Is Becoming Part of Material Selection
Environmental considerations are increasingly incorporated into construction-material decisions.
This includes product formulation, emissions, durability, material efficiency and the overall performance of building systems.
For sealants, longer service life and appropriate material selection can also contribute to the durability and performance of building envelopes.
Quality, Responsibility and Long-Term Partnership
The past year has reinforced something that has been central to SIWAY since 1984:
The sealant industry is ultimately about more than sealing.
- ✓ It is about protecting buildings.
- ✓ It is about connecting materials.
- ✓ It is about supporting construction systems.
- ✓ It is about helping customers solve application problems.
- ✓ And it is about building long-term trust between manufacturers and partners.
Looking ahead, SIWAY will continue to focus on product development, manufacturing consistency, customized solutions, quality management and international market development.
We will continue to expand our product capabilities while staying focused on the applications where our customers need reliable sealing and bonding performance.
