Vetoflex SN787

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 substrates, Vetoflex SN787 no need for primer. Whether 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 made with a dry spatula before skin formation occurs.

Excess uncured sealant should be wipe Vetoflex SN787 d 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 SN787 must not be used on materials which can bleed certain substances over time, or directly on surfaces which may react with the oxime products released during curing, such as copper and its alloys.

Note: To avoid influence adhesion performance, pls warm the sealant above 5°C before application.
