MDI General-Purpose Polyurethane Glue

Physical state: Colorless to pale yellow, transparent liquid

Core component: Terminal isocyanate prepolymer（PureMDI system)

25Viscosity at ℃: 5000–6000 mPa·s; mixes smoothly without clumping.

Tensile strength: 0.48 MPa; elongation at break: 75%; exhibits sufficient elasticity after molding.

Packaging specifications: 20 kg small drums, 200 kg standard iron drums; full-container-load bulk exports supported.

Solvent-free, eco-friendly formulaZero-benzene solvents, low VOC—fully compliant with China’s new national standard GB 36246-2018. Construction in school campuses and indoor venues produces no pungent odors and does not pollute the surrounding environment.

Outstandingly stable physical performanceIt has moderate viscosity and exhibits excellent compatibility with black rubber granules and colored EPDM granules. After curing, it remains crack-free and does not lose granules, meeting the performance standards for shock absorption and cushioning required for sports fields.

Super strong adhesionIt can be firmly bonded to rubber granules, cement bases, and asphalt surfaces, and is resistant to delamination even after prolonged outdoor use, significantly reducing subsequent maintenance costs for the site.

Simple and efficient constructionSingle-component formulation requires no additional mixing; it can be applied manually or mixed mechanically. Its curing speed is moderate, making it ideal for large-scale projects with tight deadlines and helping to reduce labor time.

Super high cost performanceAmong PU adhesives of the same environmental protection grade, this one has a lower unit price, uses less material, and generates minimal waste—making it the preferred material for small- and medium-sized playgrounds and community running track projects.

Objective shortcoming alert: The product exhibits moderate resistance to UV-induced yellowing. For long-term exposure, it is recommended to use a complementary yellowing-resistant topcoat in conjunction with the surface layer.

Breathable plastic running track black elastic underlayer-specific adhesive

EPDM Colored Granule Flooring Adhesion (for Community Walkways, Children’s Play Areas, and Small Sports Fields)

Renovation and construction of primary and secondary school playgrounds, community fitness tracks, and simple athletics facilities in rural areas.

Construction of Outdoor Permeable Rubber Pavement and Elastic Layer for Park Rubber Walkways

Multi-site breathable track projects for primary and secondary schools across China: Each track uses between 2 and 10 tons of 06 adhesive per installation. After five years of completion, no large-scale delamination or blistering has been observed. School authorities have retested the environmental protection indicators, and all results have met the required standards.

Southeast Asia Overseas Campus Plastic Running Track Export Supporting Materials: Delivered by sea in 200kg drums per full container, suitable for tropical, rainy climates. Featuring a permeable structure for stable drainage, these materials enjoy a high repurchase rate among contractors.

Community Outdoor EPDM Fitness Trail Renovation Project: 20kg small-bag packaging is ideal for small, scattered construction sites, offering flexible transportation and easy access. During construction, the material mixes smoothly without clogging equipment.

Q1: Does this 06 polyurethane adhesive meet export environmental standards?

A: This is a solvent-free system that contains no volatile solvents such as toluene or xylene, meeting the requirements of China’s new national standards and supporting export customs clearance for projects in overseas markets such as Southeast Asia and the Middle East.

Q2: With a viscosity of 5,000–6,000 mPa·s, will it be difficult to mix during construction?

A: The standard viscosity range of 25℃ is compatible with most track mixers, ensuring uniform dispersion of EPDM granules when mixed at room temperature. In hot summer conditions, the viscosity slightly decreases; in cold winter conditions, the material can be placed indoors in advance to warm up before construction begins.

Q3: If I only buy this glue to use as the track surface layer, will it turn yellow?

A: This product has relatively weak yellowing resistance and may slightly turn yellow after prolonged exposure to outdoor conditions. If the site has high requirements for the appearance color, we recommend applying an additional layer of yellow-resistant polyurethane topcoat to ensure both durability and aesthetic appeal.

Q4: How do I choose between 20 kg and 200 kg packaging?

A: For small trails and renovation/repair projects, choose the 20-kg small drum—low wastage and easy storage. For newly built standard sports fields and bulk export orders, prioritize the 200-kg large drum—lower unit procurement cost and ideal for containerized bulk shipping.

Q5: Can this adhesive be used for the base layer of breathable running tracks?

A: Specifically designed for breathable track elastic underlayers and EPDM base layers, this adhesive is formulated with black granules to ensure uniform porosity in the permeable underlayer, meeting stringent drainage performance standards. It is the mainstream adhesive of choice for breathable running tracks.

Q6: What are the precautions for storage and transportation?

A: Store in a sealed container in a cool, dry warehouse, away from rain, direct sunlight, and water sources. As a polyurethane chemical, it can be transported by sea or land according to standard regulations for general chemical and construction materials.
