Silicone Sealant Low Modulus

Technical Data Sheet

1.  DESCRIPTION

Antel Low Modulus Silicone Sealant is a one part flexible silicone sealant self priming to most construction materials.

2.  USES

Can be used for a wide range of applications including sealing expansion and control joints in precast concrete panels and metal curtain walls, non structural glazing systems, perimeter sealing if doors, widow frames and panels.  Its hygienic surface when cured makes it particularly suitable for use in refrigeration systems.

Suitable for PVC widow frames and panels.

3.  PACKAGING        

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

4.  COLOUR

White and Clear

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 building materials that bleed oils, plasticisers or solvents.

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

Do not apply to surfaces which are to be painted as the sealants subsequent movements will cause the paint film to crack
