Silicone Sealant Bathroom & Kitchen

Technical Data Sheet

1. DESCRIPTION

Antel Bathroom and Kitchen Silicone Sealant is a one part flexible silicone sealant for sanitaryware and non porous surfaces.  Contains anti fungicide properties and therefore resists mildew and mould attack even under hot or humid conditions.  Also has resistance to moisture, hot oils, free steam, oxygen, ozone and ultra violet radiation.  Will not shrink, crack or discolour.

2.   USES

Especially designed as an interior sealant for use in sealing sanitaryware.  The result gives a permanently flexible, waterproof seal around bathroom fixtures, toilets, kitchen fittings, sinks, showers and ceramic tile grouting.   The sealant can be used in factory situations, for in-plant assembly or directly on site.

3.   PACKAGING  

310 ml plastic cartridge complete with nozzle.  Packaged 12 per box.

4. COLOUR

White.

5.   STORAGE/SHELF LIFE      

Store in cool, dry conditions.  Protect from freezing.

Keep out of reach of children.

Shelf life - 12 months from date of shipment when stored below 32°C.  Previously opened cartridges may be used by simply removing the cured plug of sealant from the top of the nozzle.

6.   HEALTH & SAFETY

On contact, uncured silicone will irritate the eyes.  In case of contact, remove the sealant and flush eyes thoroughly with water.   If irritation persists seek medical attention.  Avoid prolonged or repeated skin contact.  Until fully cured silicone releases acetic acid.  Ensure adequate ventilation during application.  KEEP OUT OF REACH OF CHILDREN.

7.   LIMITATIONS

Not recommended for joints where abrasion or physical abuse are encountered.

Do not apply to surfaces in direct contact with food as the silicone contains fungicide.

Do not apply to building materials that bleed oils, plasticisers or solvents.

Do not use in totally confined spaces as atmospheric moisture is required for the curing process.

Not recommended for bonding to substrates where acetic acid released during cure could react to the surfaces to which the sealant is in contact. (E.g. concrete, cement, mortar, certain metals).
