Adhesive Systems

SPABOND 340LV

EPOXY ADHESIVE SYSTEM
  • High strength and toughness industrial adhesive
  • Excellent gap filling properties
  • Designed for cartridge and mixing machine dispense
  • Three hardener speeds give a range of working times / clamp times
  • Low exotherm and shrinkage
  • Resin & hardener are pigmented to give a visual indication of mix quality
  • Temperature performance up to 90°C / 195°F

Spabond 340LV is a high performance adhesive designed for bonding large structures. It is a cost-effective system with good thermal and mechanical properties.

The components are pigmented to give a visual indication of mix quality, which is a useful feature when mixing by hand or with a machine. The system has a simple 2:1 mix ratio by volume and weight.

Typical Applications

Large structures such as yacht hulls and wind turbine blades.

Pack Sizes & Availability

Spabond 340LV is available in cartridges, pails and 200 litre drums for machine mixing / dispense.
