Polyurethane Adhesive for Construction

1C polyurethane adhesive certified for wood construction

XILOBOND T is a single-component, moisture-curing polyurethane adhesive formulated with special high-performance polyurethane resins. It is designed for structural bonding of engineered wood. It does not contain solvents, formaldehyde, or heavy metals.

XILOBOND T is suitable for bonding conifers such as silver fir, spruce, and pine, intended for the production of blockboard and laminated panels for external doors and windows, and semi-finished products subject to high exposure to temperature and humidity. XILOBOND T can be used for the production of structural laminated wood, Bilam beams, Trilam beams, and X-LAM panels. Suitable for bonding heat-treated wood species (such as Thermowood®).

CERTIFICATION OF THE ADHESIVE

Adhesives for structural applications must produce joints with sufficient strength and durability to preserve the integrity of the bond in the assigned service class throughout the expected lifetime of the structure. XILOBOND T meets the classification requirements for type I adhesives in standard EN 15425:2008.

EN 302-1 shear strength of the joint under longitudinal traction for thin joints 0.1 mm and thick joints 0.5 mm
EN 302-2 resistance to delamination
EN 302-3 effect of acid attack on wood fibers, due to cyclic temperature and humidity treatments, on transverse tensile strength
EN 302-4 effect of wood shrinkage on shear strength
EN 15416-2 static load on specimens with multiple gluing lines in compression shear
EN 15416-3 deformation due to creep under cyclic climatic conditions on specimens subjected to shear loads by bending
EN 14080:2013_Annex B2 static load on specimens under cyclic climatic conditions
EN 15416- 5 determination of conventional pressing time

The single-component polyurethane adhesive XILOBOND T type I according to EN 15425:2008 is suitable for the production of structural products according to EN 14080:2013.
