Vetoflex SA786

The movement capability of sealants as well as local regulations must be considered. Joint width should be twice the depth.

The joint faces to be bonded must be clean, dry and free from dust, oil, grease, old sealant and any traces of contaminant which may affect adhesion. Surfaces should be degreased with solvent soaked cloth and then wiped with a clean cloth. To remove dust, use oil-free compressed air

For almost all substrates, Vetoflex SA786 no need for primer. Whether to use primer or not when applied on special substrates, prior test is recommended.

For good performance it is essential that the sealant is only bonded to the two facing sides of the joint. To achieve this, install a backup material (closed cell polyethylene or open cell polyurethane foam). Apply the sealant in a continuous operation making sure all air pockets or voids are eliminated. Tool the sealant with light pressure to spread the material against the joint surfaces.

This operation should be done with a dry spatula before skin formation occurs.

Excess uncured sealant should be wiped and cleaned with a commercial solvent, cured sealant can only be removed by scraping (i.e. with a razor blade), or with a special silicone remover product.

• Vetoflex SA786 must not be used on sensitive surfaces which could react with the acetic acid, which is released during cure, nor should it be used on materials where migration of constituents can take place, e.g. certain rubbers. 
• Vetoflex SA786 must not be used for sealing aquariums (presence of fungicide). 
• Vetoflex SA786 is not recommended where abrasion or physical abuse will be encountered.
