Hybrid Polymer Sealant is a new sealing material developed based on MS polymer technology, combining the advantages of silicone and polyurethane adhesives. It cures to an elastomer through moisture curing, is solvent-free, and is isocyanate-free, offering a neutral cure, environmentally friendly odorlessness, and low VOC emissions.

Hybrid Polymer Sealants Usage
- The best environmental conditions for the construction of the sealant are temperature 4 ℃ ~ 40 ℃, relative humidity of 40% ~ 80%.
- Clean the surface of adhered or coated objects before use, and use suitable solvents including anhydrous alcohol, isopropyl alcohol, acetone and so on.Remove rust, dust, oil and water.
- Cut the nozzle with a paper cutter, squeeze the adhesive onto the cleaned surface, make it evenly distributed, and close the sticky surface and fix it within the surface drying time.Put the coated parts in the air and let them cure at room temperature for 24 hours before putting them into use.
- After the operation is completed, the unused adhesive should be tightened the cap immediately, sealed and stored. When using again, if there is a little crust at the sealing place, it can be removed without affecting the normal use.
Product Features
1. Low VOC Emissions
This Hybrid Polymer Sealants utilizes a neutral, room-temperature curing system, is odorless, and has a VOC content of less than 30g/L, complying with EU REACH and RoHS environmental standards. The solvent-free formula makes it safer and more environmentally friendly for packaging, medical, and electronics applications.
2. Highly Compatible
Hybrid Polymer Sealants does not corrode sensitive materials such as metal, glass, and plastic. It exhibits excellent adhesion to aluminum, stainless steel, galvanized steel, PVC, polycarbonate, and ABS.
3. Excellent Weather Resistance
It resists UV rays, ozone, aging, and extreme temperature fluctuations. Temperature resistance ranges from -40°C to +120°C, with short-term high-temperature resistance up to 150°C. It maintains excellent adhesion and elasticity even under long-term outdoor exposure.
4. Excellent Electrical Insulation Properties
Hybrid Polymer Sealants offers excellent electrical insulation properties, is non-conductive, and does not cause corrosion or electrochemical reactions, making it safe for use in electronic components, medical equipment, and refrigeration systems.
5. Strong Wet Surface Application Capability
Unlike traditional silicone sealants, this sealant can be applied directly in wet or humid environments without affecting cure speed or bonding performance, making it ideal for outdoor use or in high-humidity areas.
Applications
1. Building Structural Sealing
Used for exterior wall joints, aluminum window frames, curtain wall assembly, roof waterproofing, concrete expansion joints, and more. Its excellent water resistance and weather resistance ensure long-term sealing, preventing water seepage and structural degradation.
2. Automotive Manufacturing and Body Assembly
It is widely used in automotive body welding, chassis seams, roof sealing, and glass installation. Its shock-resistant properties reduce vibration and noise, improving the vehicle’s airtightness and waterproofing.
3. Electrical and Electronic Packaging
Hybrid Polymer Sealant is non-conductive and non-corrosive to electrical materials, making it suitable for PCB component mounting, cable sealing, and control box packaging.
4. Medical and Refrigeration Equipment
It is used in medical equipment, refrigerated display cases, refrigerators, and air conditioning systems to seal against moisture and prevent refrigerant leakage, ensuring equipment safety and efficiency.
5. Mechanical Equipment and Assembly
It is suitable for applications such as mechanical equipment body seams, screw hole sealing, and fuel tank edge sealing. It can withstand vibration and alternating high and low temperatures while maintaining stable bonding performance.
6. Marine and Outdoor Engineering
With outstanding salt spray and UV resistance, it is suitable for sealing and repairing in harsh environments such as ship decks, container repair, and outdoor electrical equipment.
