Silicone Sealant Low Modulus Technical Data Sheet
Antel Low Modulus Silicone Sealant is a one part flexible silicone sealant self priming to most construction materials.
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 P V C widow frames and panels.
310ml plastic cartridge complete with nozzle. Packaged 12 per box.
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.
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
