DNV-GL Certified Formats Available
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 time 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, straight-sided pails and 205 litre drums for machine mixing and dispense.

PRODUCT DESCRIPTION STATUS CERTIFICATION
Spabond 340LV Resin and HT Hardeners Approved
DNV-GL
TAK00001H8
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 2 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 temperature can cause crystallization.
Containers should be firmly closed. Hardeners, in particular, will suffer serious degradation if left exposed to air.
For more information on crystallization please refer to the Adhesives section on the Gurit website. (www.gurit.com)

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.
SURFACE PREPARATION
Before using the product ensure that surfaces to be bonded are clean, dry and dust-free. Prepare all surfaces by abrading with medium grit
paper or other suitable abrasive, remove dust then wipe with acetone.
Metals – requires a chemical pre-treatment to create the best bond. Please contact Gurit for a Guide to Surface Preparation and Pre-treatments.
Polyester or vinylester – ensure laminates are fully cured before bonding, then prepare as above.
Epoxy laminates – it is recommended to use a suitable Peel Ply as the last stage in their manufacture, otherwise prepare as above. Trials may
be required to test Peel Ply suitability.
Ferrocement – etch with 5% solution of hydrochloric acid, wash with fresh water, then dry.
Timber – sand with abrasive paper across grain. Degrease oily timber with a fast evaporating solvent (e.g. acetone). For resinous or gummy
timber, etch with 2% caustic soda solution, wash off with fresh water and dry.
MIXING & HANDLING
Gurit recommends mixing machine dispense. If mixing by hand, mix thoroughly for at least one minute, paying particular attention to the sides
and bottom of the mixing vessel, to ensure no streaks remain. Once fully mixed the adhesive should have a uniform colour. Use from pot quickly
to maximise resin working life.
CARTRIDGE USE
If dispensing product from a two component cartridge, first prime the cartridge by dispensing slowly until both resin and hardener are at the
outlet of the cartridge. Secondly, clean the outlet and attach the mixing head. When starting a new cartridge, dispense and discard a small
amount of adhesive (typically the length of a mix head) prior to applying adhesive to the substrate, in order to ensure thorough mixing of the
system. If using a pneumatic gun, regulate supply air pressure to a maximum of 4 Bar. Relieve the pressure on the cartridge after use.
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 this occurs flush the eye with water
for 15 minutes, holding the eyelid open, and seek medical attention.
4. Ensure adequate ventilation in work areas. Respiratory protection should be worn if there is insufficient ventilation. Solvent vapours should
not be inhaled as they can cause dizziness, headaches, loss of consciousness and can have long term health effects.
5. If the skin becomes contaminated, then the area must be immediately cleansed. The use of resin-removing cleansers is recommended. To
finish, wash with soap and warm water. The use of solvents on the skin to remove resins etc must be avoided.
Washing should be part of routine practice:
before eating or drinking
before smoking
before using the lavatory
after finishing work
6. The inhalation of sanding dust should be avoided and if it settles on the skin then it should be washed off. After more extensive sanding
operations a shower/bath and hair wash is advised.
APPLICABLE RISK & SAFETY PHRASES
Gurit produces a separate full Safety Data Sheet for all hazardous products. Please ensure that you have the correct SDS to hand for the
materials you are using before commencing work.
