Thermally Activated PUR Adhesives for High-Performance Substrate Bonding

Product Overview

Runshine New Materials (Foshan) Co., Ltd. offers a series of high-performance, thermally activated, moisture-curing polyurethane (PUR) hot melt adhesives engineered for high-speed flat lamination processes across diverse climatic conditions. These reactive thermoset systems provide strong, durable bonds to a wide variety of substrates including MDF, wood veneers, metals, plastics (PET, acrylic), SPC, and carbon crystal panels. Formulated with specific ambient temperature tolerances (0°C to 43°C) and controlled open times (4-30 minutes), they ensure excellent processing adaptability, high production yield, and reliable performance. Key characteristics such as excellent aging resistance, thermal stability, and tailored reactivity—including specialized efficacy for PET films—make them ideal for demanding furniture, interior decoration, and architectural applications. All products are designed for application at 110°C - 140°C and support sustainable manufacturing with low VOC emissions.

Key Features

✧ Moisture-curing polyurethane (PUR) chemistry – Provides superior bond strength and durability through a reactive curing mechanism that forms cross-linked networks resistant to heat, aging, and solvents.

✧ Controlled open time versatility – Available in formulations with open times ranging from 4 to 30 minutes at 25°C to accommodate various production speeds and complex assembly processes.

✧ Broad ambient temperature applicability – Specific grades are engineered to perform reliably in ambient temperatures from 0°C to 43°C, ensuring consistent processing year-round and across climate zones.

✧ Optimized viscosity profile – Offers stable viscosity values between 5,000–10,000 mPa·s at 130°C, ensuring excellent wetting and flow characteristics on both porous and non-porous substrates.

✧ High-temperature resistance – Developed to maintain bond integrity under elevated temperatures, making it suitable for post-processing environments and demanding end-use conditions.

✧ Exceptional substrate compatibility – Demonstrates strong adhesion to a wide range of materials including MDF, wood veneers, PET films, acrylics, aluminum, SPC, and carbon crystal panels.

✧ Superior aging and durability performance – Resists yellowing and degradation over time, ensuring long-term structural and aesthetic integrity in architectural and interior applications.

✧ High-yield application efficiency – Formulated for optimal spread rate and minimal waste, supporting cost-effective manufacturing with high production output.

Applications

Our thermally activated, moisture-curing polyurethane (PUR) hot melt adhesives are engineered for high-performance bonding across a broad spectrum of decorative and industrial laminating applications. These adhesives deliver robust durability, thermal resistance, and superior substrate compatibility, meeting stringent international standards for quality and performance.

◊ Decorative flat lamination on engineered wood panels – Provides strong, durable bonds for MDF, particleboard, and multi-density fiberboards used in furniture, cabinetry, and interior cladding

◊ PET film lamination onto wood-based substrates – Specially formulated variants (e.g., YKM8608, YKM8607) ensure high yield and excellent adhesion in high-speed finishing processes

◊ Metal composite material (ACM) bonding – Suitable for laminating aluminum and other metal sheets to core materials in architectural panel production

◊ Rigid plastic panel lamination – Bonds acrylic, SPC (stone plastic composite), and carbon crystal panels with high heat and aging resistance

◊ Veneer and foiled panel production – Ensures consistent bonding performance across a range of open times (4–30 minutes) to accommodate varying line speeds and ambient conditions

◊ Low-temperature environment laminating operations – Certain grades (e.g., YKM8607) maintain viscosity and open time stability in challenging conditions down to 0°C

◊ High-temperature end-use applications – Delivers reliable performance in environments requiring thermal endurance, such as kitchen cabinets, bathroom fixtures, and exterior architectural elements
