Engineered for architectural glazing, climate barriers, and structural joint integrity across Finland's building envelopes.
The construction and civil infrastructure sectors in Finland run on some of the strictest material quality benchmarks globally. Driven by the climate extremes of the subarctic environment, structural expansion joints are subjected to massive thermal movements. Materials experience rapid temperature swings from hot, UV-intense summer afternoons to freezing winter nights down to -35°C. Conventional polyurethane (PU) and silicone sealants are frequently challenged under these conditions. PU sealants tend to degrade rapidly under UV exposure and turn brittle at low temperatures. Silicones, although elastic, suffer from plasticizer migration, leading to aesthetic staining of expensive porous granite and timber facades common in Helsinki, Espoo, and Tampere.
Consequently, Finnish structural engineers, building designers, and window manufacturers are turning heavily to Modified Silane (MS) Polymer Sealants. Combining the outstanding weatherability and UV-stability of silicones with the high mechanical strength and paintability of polyurethanes, MS Sealant technology provides an optimal moisture-curing system with high elastic recovery. This creates durable, long-term seals for triple-glazed window installations, prefabricated timber structural envelopes, and concrete expansion joints.

How Modified Silane (MS) Polymers outclass traditional Polyurethanes and Silicones in Nordic climates.
| Performance Property | Silyl-Terminated Polyether (MS Polymer) | Traditional Polyurethane (PU) | Acidic / Neutral Silicone |
|---|---|---|---|
| Elastic Recovery (ISO 7389) | > 90% - Highly elastic recovery without permanent deformation. | Moderate (~70%) - Subject to creep and compression set. | Excellent (> 90%) - High elasticity. |
| Sub-Zero Modulus Stability | Stays flexible down to -40°C; does not crystallize or crack. | Stiffens significantly below -10°C; risk of cohesive failure. | Remains flexible; low mechanical shear strength. |
| Paintability (Over-paintable) | Yes, directly paintable with water-based systems without cracking. | Yes, but requires extensive curing before painting. | No, paint cannot adhere to the silicone matrix. |
| Eco-Safety / VOC Profile | Zero Isocyanate, solvent-free, complies with Finland M1 rating. | Contains Isocyanates, requires health warnings, high odor. | Low toxicity but can release acetic acid/oximes during cure. |
| Staining on Natural Stone | No plasticizer migration, no staining of granite or wood. | Low risk of migration, but can yellow on wood surfaces. | High risk of oil migration (staining adjacent masonry). |
Our MS polymers are formulated to meet Class 25LM specifications. This ensures high joint movements (±25% or more) can be accommodated without adhesive or cohesive failure, even during severe winter contractions of steel, glass, and concrete components.
Finland values sustainable indoor air quality. Our formulations are free of solvents, silicones, and heavy metal catalysts. This guarantees compliance with Finnish low-emission standards, making them highly suitable for residential passive houses.
With high UV-curing resistance, our sealants resist solar radiation degradation. They do not turn yellow, chalk, or develop micro-fissures, preserving the airtight envelope for over 25 years.
In modern industrial sourcing, reliable supply chains are essential. Shandong Jinfang Adhesive Industry Co., Ltd. operates a fully integrated, state-of-the-art production plant in China. Leveraging advanced Industry 4.0 automated systems, we control everything from chemical compounding to automated cartridge injection and smart cartoning.
By partnering with major academic institutions such as Shandong University, Xiamen University, and Linyi University, we have developed advanced R&D systems. This allows us to optimize raw material usage, adjust curing properties for different climates, and scale production rapidly without compromising quality. The result is a highly competitive pricing structure combined with consistent quality control, certified under ISO 9001, ISO 14001, and EU IROS standards.
Providing end-to-end design, formula adjustment, and customized packaging for the Finnish and Scandinavian markets.
We modify curing speeds, mechanical modulus (low, medium, high), and visco-elastic performance to align with different application temperatures. This includes winter-grade formulations suitable for application in cold climates.
Our options include 290ml/300ml rigid plastic/aluminum tubes, 600ml foil sausages, and bulk industrial pails. All packaging is designed to resist vapor transmission and maintain product shelf life during transit.
We provide high-resolution lithographic offset printing directly on tubes, or customized adhesive labeling. Our in-house design team ensures brand consistency and helps customize technical details to local regulatory requirements.
Our logistical framework ensures efficient transit times from our automated production facilities to key industrial hubs and ports across Finland, including Helsinki, Kotka, and Turku. Through coordinated ocean freight networks and intermodal rail connections, we deliver consistent supplies of sealants and adhesives directly to distributors and construction companies. We handle necessary certifications and customs documentation to ensure a seamless import process into the EU single market.
