EVO-STIK 613

SURFACE PREPARATION:

- Substrates to be bonded should be perfectly clean dry and free from dust and grease.

- Smooth or polished surfaces should first be roughened with fine abrasive.

- If degreasing is necessary, a detergent/water treatment should first be considered. If this is inappropriate a suitable solvent e.g. Bostik Cleaner 5 may be used. It is advisable to check the effects of degreasing solvents on plastics, rubber materials and painted surfaces before carrying out the operation. All traces of cleaning solvents must be allowed to evaporate completely before application of the adhesive.

APPLICATION:

- Evo-Stik 613 can be applied by brush or serrated spreader.

- Apply an even ribbed coat of adhesive to both surfaces using a serrated trowel or spreader. For correct coverage use the spreader at such an angle as to give good rib formation after drying. If a white “bloom” appears on the surface, raise the temperature and/or dry the atmosphere.

ADDITION OF ACCELERATOR FOR INCREASED HEAT RESISTANCE

- For temperature resistance above 60°C stir into the adhesive an addition of 5% Accelerator F (by weight) then use in the normal way. - The mixture has a pot life of approx. 4 hours.

DRYING

- Drying time depends on film thickness, surface porosity, temperature and humidity.

- Minimum drying time 20 minutes - this is to ensure through drying of the adhesive film, the surface may feel touch dry prior to this but bonding too early can cause problems of solvent entrapment, resulting in poor bonding.

NORMAL BONDING METHOD:

- Bring the two dry, coated surfaces into contact within 60 minutes of application and press together over the entire bond area.

- To obtain optimum initial bond strength, surfaces should be bonded as soon as possible after recommended drying time.

- Apply as much pressure as possible by hand roller, static press or nip roller without causing damage. Sustained pressure is not necessary.

- Bringing the surfaces together before the surfaces are touch dry will result in solvent being trapped, adversely affecting the final bond, and possibly giving rise to blistering problems.

- The initial bond strength allows immediate handling, but maximum bond strength is reached after 24 - 48 hours.

SPECIAL BONDING METHODS:

In some applications it is convenient to pre-coat components some time before assembly is required. Evo-Stik 613 may be adapted to this type of use by means of reactivation processes. The adhesive film must be kept free from contamination.

Evo-Stik 613 is a general purpose, contact adhesive particularly suitable for bonding plastic laminates and other rigid plastics (excluding polvethvlene and polypropylene) on particleboard, MDF, woods, metals and al type of board with the exception of bituminous materials

Evo-Stik 613 may also be used to bond boards of insulating and cane fibre rigid polyurethane foam laminated panels and acoustic tiles to suspended oi vertical surfaces such as flat surfaced ceilings or walls. Most types of rigid plastic nosings and covings may also be bonded.

Evo-Stik 613 is intended for interior use. It is not suitable for use with expanded polystyrene foam and is also unsuitable for use where only point contact Is obtainable between the surfaces to be bonded
