Spabond 340LV HT EPOXY ADHESIVE SYSTEM ¬ Reduced component weights; lower density when compared to glass filled adhesives ¬ Higher thermal performance & fast cure progression ¬ 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 ¬ Temperature performance up to 90°C ¬ Resin & hardener are pigmented to give a visual indication of mix quality ¬ GL approved INTRODUCTION Spabond 340 LV HT 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. The formulation gives high thermal performance and allows fast curing, making this product ideal for bonding large composite structures where minimising cure times and increasing productivity is of value. 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. Spabond 340LV HT is available in cartridges, pails and 200 litre drums for machine mixing/dispense.

Mixing & Handling INSTRUCTIONS FOR USE The product is optimised for use at 15 - 25°C. At lower temperatures the components thicken and may eventually become unworkable. To ensure accurate mixing and good workability pre-warm the resin & hardener as well as the surfaces to be bonded before use. The Spabond 340LV components are supplied pigmented in the following colours: Resin Fast Hardener Slow Hardener Extra Slow Hardener yellow red purple blue Surface Preparation Before using the product ensure that surfaces to be bonded are clean, dry and dust-free. Prepare all surfaces by abrading with...

HEALTH AND SAFETY The following points must be considered: 1. Skin contact must be avoided by wearing protective gloves. Gurit recommends the use of disposable nitrile gloves for most applications. The use of barrier creams is not recommended, but to preserve skin condition a moisturising cream should be used after washing. 2. Overalls or other protective clothing should be worn when mixing, laminating or sanding. Contaminated work clothes should be thoroughly cleaned before re-use. 3. Eye protection should be worn if there is a risk of resin, hardener, solvent or dust entering the eyes. If...

Transport & Storage The resin and hardeners should be kept in securely closed containers during transport and storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any other absorbent material. The area should then be washed clean (see appropriate Safety Data Sheet). Adequate long term storage conditions will result in a shelf life of two years for both the resin and hardeners. Storage should be in a warm dry place out of direct sunlight and protected from frost. The storage temperature should be kept constant between 10°C and 25°C, cyclic fluctuations in...
