Two-component polyurethane adhesive Bonding for sound insulation
materials and composite building products ROHS SGS for Sports
Recreation Waterborne Used for Bonding Building

Product Overview
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.

Superior Bonding Performance
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.

Application Areas:
- Insulated box cars and trains
- Composite sandwich panels
- Cleanrooms, cleanroom metal partitions and ceilings
- Composite PU board, rock wool board, paper honeycomb board,
aluminum honeycomb board, gypsum board, etc.
- Marine partition boards, composite rock wool board, etc.
- Curtain walls: Aluminum honeycomb panel, stone honeycomb panel,
stone composite panel, etc.
Manufacturing Process:

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.
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.

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.

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.

Apply Pressure
- Bonded panels should be pressed together within the open time to
ensure proper adhesion.

Key Advantages
- Technology Fusion: Combines advanced European and American expertise with tailored
adaptations for the domestic market.
- 100% Eco-Safe: Zero volatile organic compounds (VOCs), ensuring non-toxic
application and compliance with strict environmental regulations.

Frequently Asked Questions
What is the target application for your prepolymer?
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.
What are your specific performance requirements?
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.
Do you require a specific curing agent or system?
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.
What is your required sample quantity for testing and evaluation?
We provide free samples (typically 1-2 kg) for R&D purposes.
Please specify the quantity needed to conduct your initial trials.
What certifications or quality standards are mandatory for your
project?
Our products are SGS and ROHS certified. Inform us if you need
additional certifications like ISO, REACH, or specific industry
standards.
What is your estimated monthly or annual consumption volume?
Providing your forecasted volume (kg/month or tons/year) allows us
to structure the most competitive pricing and ensure supply chain
stability.
What is your target price per kilogram?
While we strive to offer the best value, sharing your budget helps
us find a solution that meets both your performance and cost
requirements.
Do you require technical support during product development or
production?
Our technical team can provide guidance on formulation
optimization, processing parameters, and troubleshooting. Let us
know your level of support needs.
