Silane‑modified polymers (SMPs) are hybrid adhesive and sealant systems that combine the benefits of classical polymer technology with reactive silane groups. They meet the highest requirements for elastic bonding and sealing and offer:

• Excellent adhesion – AlMg1, AlMg3, steel, PVC, glass, PC, ABS
• Cost‑efficient processing
• Outstanding mechanical properties – elongation at break up to 700%, Shore A Hardness between 25 and 60
• High resistance and durability – hydrolysis and chemical resistance, UV and aging stability
• High temperature stability – continuous up to 100°C, short‑term up to 120°C
• Excellent health and environmental compatibility – solvent‑ and isocyanate‑free, no hazard labeling required
• Availability in all common packaging sizes – cartridges, tubular bags, pails, drums

Michael Wahl, Director Business Center Casting Resins & Elastomers (CASE) at RAMPF Advanced Polymers – “SMPs offer exceptional formulation flexibility. With our encompassing R&D capabilities, we develop products precisely tailored to our customers’ requirements, ensuring maximum performance and quality while maintaining easy processability. We support our customers from product development all the way through to series production.”

Customized SMP systems from RAMPF Advanced Polymers are used in a wide range of industries and applications, including:

• Building technology – sealing and bonding of cooling, ventilation, and air‑conditioning systems
• Automotive and transport – bonding of control components; sealing of sensors, connectors, and electronic modules
• Household appliances – assembly of washing machine covers
• Construction – insulation elements, formwork elements

Product Highlights: RAKU^® SEAL 45‑1067 and RAKU^® SEAL 45‑2067

RAKU^® SEAL 45‑1067 (one component) and RAKU^® SEAL 45‑2067 (two components) are solvent‑ and isocyanate‑free adhesive and sealant systems based on silane‑modified polymer technology. Key advantages of these high‑performance systems include:

• Very broad adhesion spectrum, even without primer
• High elasticity
• Excellent aging and weather resistance
• High hydrolysis resistance
• Strong chemical resistance
• Operating temperature: -40°C to +100°C (short‑term up to +120°C)

RAKU^® SEAL 45‑2067 – the ultra-fast two‑component system: The two‑component sealing system RAKU® SEAL 45‑2067 offers rapid handling strength, enabling very short process times. With individually adjustable reactivity, the system can be precisely tailored to the customer’s production process.

RAKU® SEAL 45‑1067 – the efficient one‑component system: The one‑component sealing system RAKU® SEAL 45‑1067 stands for maximum production efficiency. There is no mixing technology required, resulting in significant time and cost savings. At the same time, the system ensures reliable, consistently high quality.
