Power Adhesives 440B Bead and Spray Biodegradable Hot Melt Slug

Power Adhesives Tecbond 440B is a biodegradable hot melt adhesive engineered for bead and spray application, delivering outstanding versatility for packaging and product assembly. Compatible with Tec spray applicators and bulk hot melt machinery, 1-3/4" (43 mm) 440B glueslugs provide a long open time of up to six minutes, giving operators flexibility to position and adjust components before setting. Its high molten tack offers instant hold and reduces creep in compressed bonds, while delivering reliable adhesion to plastics, foam, wood, and cardboard. FDA 175.105 compliant for indirect food contact, Tecbond 440B enables sustainable manufacturing without sacrificing performance or efficiency.

Best Applications for Tecbond 440B

Packaging & Carton Sealing: Provides strong, consistent bonds across a variety of substrates.
Furniture & Upholstery: Delivers clean, durable adhesion for fast-paced production environments.
Foam & Insulation: Bonds foam and insulation materials without the need for additional fasteners.
HVAC Applications: Secures insulation inside heating and air conditioning units.
Mattress Assembly: Combines flexibility with high bond strength to improve production efficiency.
Point-of-Sale Displays: Creates neat, reliable bonds that maintain presentation quality.
General Product Assembly: Versatile bonding for plastics, wood, cardboard, and more.

Eco-Friendly Features

Formulated with 45% bio-based content, Tecbond 440B offers a sustainable alternative to conventional bulk hot melt adhesives. It meets the following internationally recognized environmental standards:

ASTM D6400
ASTM D6866
ASTM D6954
EN13432

Under industrial composting conditions, exposure to heat, oxygen, and UV light begins the breakdown process. As the adhesive’s polymer chains degrade, naturally occurring microorganisms complete the cycle without leaving behind microplastics or harmful residues.

For maximum shelf life and performance, store Tecbond 440B in its original sealed packaging, away from direct sunlight, and at temperatures below 86°F (30°C).

Non-Biodegradable Alternative

Tecbond 440B is the biodegradable version of our popular Tecbond 440 hot melt adhesive. For applications where biodegradability is not a requirement, the standard Tecbond 440 offers the same performance in a non-biodegradable formulation.
