In the Russian construction market, sealants are frequently exposed to outdoor environments characterized by extreme cold, harsh climates, and significant temperature fluctuations. Traditional sealants often suffer from issues such as low-temperature cracking, loss of elasticity, insufficient adhesion to concrete and building facades, and the need for primer application. STP (Silane-Terminated Polyurethane) sealant, however, maintains stable adhesion, elasticity, and weather resistance even in low-temperature environments, providing a more reliable long-term solution for building joints.

Applications for Russian Construction Projects
1. Exterior Facade Joint Sealing
Used for structural joints on exterior facades, such as curtain wall systems, concrete slab joints, and building expansion joints, maintaining stable sealing performance under long-term outdoor exposure.
Project Requirements:
- Resist long-term UV and weather erosion to minimize aging issues
- Adapt to thermal expansion and contraction of building structures to maintain joint stability
- Prevent cracking, chalking, or seal failure during long-term use
2. Precast Concrete Structure Joints
Widely used for sealing joints in precast concrete structures in residential and public buildings.
Project Requirements:
- Excellent adhesion to concrete substrates
- Adaptability to low temperatures and seasonal temperature fluctuations
- Minimization of joint leakage and seal failure
3. Sealing Around Doors and Windows
Suitable for sealing joints between aluminum alloy door and window frames and building walls.
Project Requirements:
- Excellent air and water tightness
- Adaptability to minor structural movements
- Long-term weather resistance and resistance to aging
4. Roof and Waterproofing Detail Sealing
Used for sealing building roof joints and detail connections such as metal-to-concrete joints.
Project Requirements:
- Stable long-term waterproofing performance
- Resistance to UV radiation and outdoor weathering
- Maintains stability during vertical application; does not sag
TP650 STP Construction Sealant for Concrete & Facade Joints
TP650 Модифицированный полиуретановый герметик is 1K 310ml/ 600ml silane-modified polyurethane sealant suitable for concrete, tile, stone, and metal substrates.
1. No primer required
Can be applied directly to concrete, metal, and coated surfaces
2. Stable at low temperatures
Maintains flexibility in cold environments, reducing the risk of cracking in winter.
3. Stable weather resistance
Suitable for long-term indoor and outdoor use, with low susceptibility to aging
4. Suitable for Multiple Substrates
Suitable for bonding concrete, tiles, stone, and metal.
5. Sag-Resistant
Suitable for vertical joint applications, enhancing application stability.
Why STP Sealant Is Suitable for Russian Construction Projects
Building sealing applications are often exposed to low-temperature environments for extended periods, and many projects even require continued construction during winter or in cold conditions. This places more direct demands on sealing materials—they must not only adhere effectively but also maintain workability and long-term stability under low-temperature conditions.
STP sealant’s performance in actual projects:
TP650 STP Modified Polyurethane Sealant can be widely used for exterior facades, concrete joints, and architectural detail sealing, providing stable adhesion and sealing performance in low-temperature and outdoor environments.
- Can be applied normally in low-temperature environments without affecting on-site operations
- Resistant to cracking or failure under repeated low-temperature and temperature fluctuations
- High adaptability to substrates, reducing reliance on primers
