Low Viscosity Biodegradable Pressure Sensitive Hot Melt for Spray Applications

Power Adhesives Tecbond 902B Biodegradable PSA Adhesive

Power Adhesives Tecbond 902B is a low-viscosity and biodegradable, pressure sensitive adhesive glue designed for spray and bead applications in sustainable packaging and product assembly. 

Sustainability Advantages

A biodegradable hot melt pressure sensitive adhesive, Tecbond 902B is made from 45% bio-based materials and meets key environmental standards, including:

• EN13432
• ASTM D6400 
• ASTM D6866 
• 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 to ensure 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).

Ideal Uses & Applications

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.

It is ideal for:

• 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, such as in retail-facing applications
• Tray Assembly: Provides flexible, long-lasting bonds for complex folds and challenging substrates
• XY Plotter Applications: Supports fine line dispensing for precision assembly with a low-viscosity formula
• Furniture & Upholstery: Delivers consistent tack and strength for demanding production schedules
• Mattress Assembly: Combines flexibility and holding power for secure, long-term adhesion

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 also offers a reliable, eco-conscious solution for demanding production lines.
