Low Viscosity Biodegradable Pressure Sensitive Hot Melt for Spray Applications

Power Adhesives Tecbond 902B Biodegradable Pressure Sensitive Pillows for Spray Systems

Power Adhesives Tecbond 902B is a biodegradable, low-viscosity pressure sensitive hot melt designed for spray and bead applications in sustainable packaging and product assembly. Supplied in bulk pillows for efficient handling and consistent feeding, this adhesive delivers high tack, smooth spray patterns, and dependable bonds on paper, cardboard, wood, fabrics, metal, and select plastics. With excellent heat stability and flexibility, it resists adhesive creep in warmer environments and remains strong in low temperatures. FDA 175.105 compliant for indirect food contact, Tecbond 902B offers a reliable, eco-conscious solution for demanding production lines.

Ideal Uses for This Biodegradable PSA Hot Melt

• Carton Closing: Creates durable, tamper-resistant seals that outperform staples and tapes.
• Packaging Inserts: Keeps inserts securely in place to protect products and maintain brand presentation.
• Point-of-Sale Displays: Bonds without detracting from visual appeal, ideal for retail-facing applications.
• Tray Assembly: Provides flexible, long-lasting bonds for complex folds and challenging substrates.
• XY Plotter Applications: Low-viscosity formula supports fine line dispensing for precision assembly.
• Furniture & Upholstery: Delivers consistent tack and strength for demanding production schedules.
• Mattress Assembly: Combines flexibility and holding power for secure, long-term adhesion.

Sustainability Advantages

Tecbond 902B is made with biodegradable, 45% bio-based materials and meets key environmental standards, including EN13432, ASTM D6400, ASTM D6866, and ASTM D6954. This formulation is engineered to break down naturally when exposed to oxygen, UV light, and heat, leaving no microplastics or harmful residues. Once the polymer structure degrades, microorganisms consume the remaining material, ensuring a clean, eco-conscious end of life.

To preserve performance and shelf life, store Tecbond 902B in its original packaging, away from direct sunlight, and at temperatures below 86°F (30°C).
