A supporting role - Special adhesives for load-bearing glulam
Manufacturers of wood elements for load-bearing construction purposes face great challenges. The production process is subjected to special standards and used adhesives have to be approved for building purposes and certified. Additionally, each individual application, whether fingerjointing or lamination, has a unique set of requirements.
We can supply a product portfolio with one-component, moisture-curing polyurethane prepolymer adhesives which are adapted specifically to different applications and products from glued laminated timber (GLT) to cross laminated timber (CLT), and from solid structural timber to I-joist formwork beams.
Several special adhesives are particularly suitable for fast and flexible production processes due to their short processing time where some other products provide a long assembly time and therefore facilitate the manufacturing of big parts and large batches.
Polyurethane adhesives provide several advantages for the manufacturing of load bearing wood parts and a superior product quality compared to other systems such as condensation resins. Prepolymers cure within a few minutes at room temperature and provide an invisible bondline due to their colourless appearance.
Mixing, pot life and adhesive remnants from too much prepared adhesive become obsolete with single component adhesives. The minimal foaming prevents the lamellas from sticking together when they are stacked on top of or next to each other and significantly reduces the cleaning effort.
