① Exclusive winter formula, application at low temperatures without heating.

Specifically formulated for low-temperature environments in autumn and winter, this PU adhesive differs from conventional PU adhesives in that it doesn’t require preheating even in cold conditions, yet still maintains excellent fluidity and mixing performance. It completely solves the common winter problems of sticky, clumpy adhesives and sluggish application, significantly boosting construction efficiency in low-temperature settings.

② Compliant with environmental regulations and the new national standards.

The product’s environmental protection indicators strictly comply with the new national standard GB 36246-2018 for safety of school grounds. It features low VOC emissions and is free of harmful volatile substances, making it environmentally friendly and safe for use in winter construction projects at primary and secondary schools, kindergartens, and public fitness facilities.

③ Excellent and stable physical performance

After curing, the tensile strength and elastic performance consistently meet the standards, making it well-suited for site curing requirements in low-temperature climates. Once formed, the material is resistant to cracking, delamination, and blistering, effectively addressing the issues of poor curing and easy damage to sites commonly encountered with ordinary adhesives during winter, thereby ensuring high-quality construction work even in cold weather conditions.

④ Ultra-low viscosity, with excellent construction adaptability.

600-800With an ultra-low viscosity of mPa·s, this material ensures uniform particle encapsulation and smooth mixing. It is suitable for both manual spreading and mechanical application. In low-temperature environments, it does not stick to equipment or settle, offering a high tolerance for construction errors and making it ideal for various winter site conditions.

⑤ Super strong adhesion, stable site structure

It exhibits strong adhesion to cement, asphalt surfaces, EPDM colored granules, and black rubber granules. Its bonding strength remains stable even at low temperatures, firmly locking the granules to the substrate and ensuring structural stability of construction sites during winter. This prevents any risk of delamination or particle loss in the later stages.

⑥ Cost-effective and ideal for winter construction projects.

A proprietary winter construction formula that eliminates the need for additional heating equipment or manual preheating, thereby reducing construction costs and shortening project timelines. With stable performance and low material wastage, this is a cost-effective, specialized adhesive ideal for synthetic surface projects in cold-climate regions.

The product features a formulation specifically designed for low winter temperatures, making it suitable for cold climates and cool autumn/winter conditions. It is not appropriate for use in high-temperature, scorching environments and cannot meet the requirements for construction under all climatic conditions. When used in high-temperature environments, it may lead to construction abnormalities; therefore, it is essential to select the product based on seasonal conditions and specific application requirements.

1. Construction of New and Renovation of EPDM Rubber Surface Layers and Base Courses in Low-Temperature Climates

2. Specialized Construction of Breathable Elastic Layer for Plastic Running Tracks in Autumn and Winter Seasons

3. Construction of sports facilities in campuses, communities, and parks in cold-climate regions

4. Various plastic sports venues and fitness trail projects rushing to meet deadlines during winter.

5. Specialized Project for Site Repair and Spot Renovation in Low-Temperature Environments

① Northern Winter Campus Track Project

Dedicated to autumn and winter low-temperature track projects in many primary and secondary schools across northern regions, this product can be directly applied without heating, perfectly addressing the common challenges of winter—such as thick, hard-to-stir adhesives and slow curing times. The resulting surface is uniformly formed and boasts strong bonding strength, with all low-temperature construction inspections meeting the required standards.

② EPDM Surface Renovation Project for Low-Temperature Regions

The renovation project for winter fitness trails in northern communities and parks has adopted a large-scale selection of ultra-low-viscosity mixtures that are highly efficient, free from clumping or sagging issues. After curing, the surface exhibits stable elasticity, remains crack-free and particle-free, significantly shortening the construction period during winter.

③ High-latitude overseas low-temperature site projects

It is widely exported to high-latitude regions and cold-weather areas in autumn and winter, perfectly suited to the local cool and low-temperature construction environments. Its heat-free construction feature makes it ideal for simple construction conditions overseas. With stable performance and a high repurchase rate, it has become a core material for site construction in low-temperature regions.

Q1: What is the biggest difference between winter-specific glue and regular, conventional glue?

A: The core advantage isLow-temperature, heat-free constructionOrdinary glue tends to become viscous and clumpy at low temperatures, requiring preheating before use—a process that’s cumbersome and can easily compromise quality. This winter-specific glue features a formulation tailored exclusively for low-temperature conditions, maintaining excellent fluidity even in cold environments. It can be applied directly and is ideally suited for autumn/winter and northern regions with low-temperature working conditions.

Q2: Is it necessary to preheat the adhesive in advance for low-temperature construction in winter?

A: No need. This product was specially developed for low-temperature environments. In typical cold weather, there’s no need to heat or allow it to warm up—simply open the container and start mixing and applying right away. This significantly reduces both construction procedures and equipment costs, making it the ideal choice for projects with tight winter schedules.

Q3: Can this glue be used in high summer temperatures?

A: We do not recommend using this product in high summer temperatures. This product features a formulation specifically designed for low winter temperatures and is suitable only for cold, cool climates. In high-temperature environments, it may become overly fluid and fail to set properly. Therefore, you should select the appropriate glue based on the season.

Q4: Is there a difference in curing speed between winter construction and construction at room temperature?

A: This product features an optimized low-temperature curing system. Compared to conventional adhesives, it offers a more stable low-temperature curing rate, eliminating issues such as prolonged non-drying or incomplete curing. After curing, its physical properties and bonding strength both meet the required standards.

Q5: How do I choose between 20 kg and 200 kg packaging?

A: For sporadic winter repairs and small-scale renovation projects, we recommend using 20-kg small buckets, which are flexible to store and have low wastage. For large playgrounds in northern regions, bulk low-temperature projects, and foreign trade export orders, the 200-kg large buckets are the preferred choice—they offer better cost performance and are ideal for full-container ocean shipping.
