Two Component Polyurethane Adhesive For Sound Insulation Materials ROHS SGS

This polyurethane adhesive series is developed by integrating European and American technologies with domestic market needs, specifically engineered for high-performance and environmental sustainability. It is a completely volatile organic compound (VOC)-free adhesive, rigorously certified to meet international standards including SGS, EU/ROHS, phthalate tests, and Shenzhen’s “Quality Control Standard for Synthetic Material Sports Surface Layers.” Designed for bonding rubber particles and sponge particles, it transforms raw materials into high-value-added products widely applied in gyms, libraries, industrial flooring, sports venues, soundproofing building materials, and more.

Advanced polyurethane adhesive offering exceptional flexibility, durability, and temperature resistance for demanding structural applications. The resilient bond layer effectively absorbs shocks and accommodates movement, making it ideal for bonding substrates with different thermal expansion coefficients.

1. Preparation Work
   • Empty mixing buckets (clean) or buckets containing the base component.
   • Mixing stick (manual or electric).
   • Electronic scale or other high-precision measuring tools.
2. Surface Preparation
   • The surface to be bonded must be dry, free of oil, dust, or other contaminants (can be cleaned with ethanol, etc.).
   • If the metal surface is primed, ensure the release agent on the plastic surface is removed.
   • Polishing the bonding surface can significantly enhance adhesion.
   • 
3. Glue Mixing
   • If the adhesive has been stored for a period, stir the base component thoroughly first.
   • Mix the adhesive in the correct ratio and use it within the working time (POT LIFE).
   • Try to use the mixed adhesive as soon as possible. If not used immediately, remix it before application.
   • 
4. Adhesive Application
   • Apply the adhesive evenly using a serrated scraper, manually or with a roller.
   • The amount of adhesive used depends on the smoothness and flatness of the surface.
   • 
5.   Apply Pressure
   • Bonded panels should be pressed together within the open time to ensure proper adhesion.

Please specify your industry and end-use, e.g., footwear (soles), industrial rollers, seals, or other elastomeric components. This helps us recommend the optimal formulation and curing system.

Please indicate your target values for hardness (Shore A/D), tensile strength, elongation at break, and abrasion resistance. Our standard M240/60D offers excellent specifications, but we can customize to meet your needs.

We typically recommend BDO or other curatives. Let us know if you have a preferred curative or if you need technical assistance in selecting the best one for your process.

We provide free samples (typically 1-2 kg) for R&D purposes. Please specify the quantity needed to conduct your initial trials.

Our products are SGS and ROHS certified. Inform us if you need additional certifications like ISO, REACH, or specific industry standards.

Providing your forecasted volume (kg/month or tons/year) allows us to structure the most competitive pricing and ensure supply chain stability.

While we strive to offer the best value, sharing your budget helps us find a solution that meets both your performance and cost requirements.

Our technical team can provide guidance on formulation optimization, processing parameters, and troubleshooting. Let us know your level of support needs.
