Bonding with Spabond 340LV

Structural Adhesive - Bonding

Spabond 340LV is a toughened, thixotropic adhesive system with a simple 2:1 by weight and by volume mix ratio.  It is designed for use with a mixing machine and has a sag resistance of 30mm on a vertical surface.

The range of hardeners available make this product ideal for bonding small or large structures. The components are pigmented to give a visual indication of mix quality.  The robust formulation ensures that the high strength and toughness performance of Spabond 340LV can be achieved even off-ratio by up to 5 or 10 parts (subject to customer requirements).

Structural adhesives used in wind turbine blade manufacture are often applied in thick bond-lines up to 40mm or 50mm in diameter and often in vertical areas of the blade.  This demands that the adhesive has good wet adhesive and thixotropic properties to ensure that it remains in place up until the point at which the two parts are brought together. 

Spabond 340 offers not only excellent sag resistance, even at high temperatures but also has a remarkable shear recovery after being dispensed through a mixing machine.  Due to its unique formulation, Spabond 340 offers excellent shear recovery and ability to resist sag when compared to its glass filled counterpart, without compromising the wetting of the bond-line surface or flow as the two components are brought together.




  • Spabond 340 - Epoxy Adhesive System (v8)
    Spabond 340 is a toughened, thixotropic adhesive system with a simple 2:1 by weight and by volume mix ratio. It is designed for use with a mixing machine and has a sag resistance of 30mm on a vertical surface.
  • Spabond 340LV - Epoxy Adhesive System (v13)
    Spabond 340LV is a high performance adhesive designed for bonding large structures such as yacht hulls and wind turbine blades. It is a cost-effective system with good thermal and mechanical properties.
  • Spabond 340LV HT (v1)
    Spabond 340LV is a high performance adhesive for bonding large wind turbine blades. It is a cost-effective system with 10% lower density than competitive glass filled adhesives and high fatigue/crack resistance.
