Polysulphide Sealant (Gun Grade & Pour Grade).
PS PG – 741 is a component sealant based on ‘THIOKOL’ – Polysulphide liquid elastomer. It consists of a ‘base compound and ‘accelerator’ (Curing Agent).
Mahaseal PS PG – 741 is a pourable grade & self leveling material used for sealing of horizontal joints only.
Features:
- Cures at ambient temperatures to a tough, elastic and flexible rubber like material.
- Bonds strongly to most of the building materials with the use of recommended primers.
- Durable, remains unaffected by UV rays, ozone and weathering conditions.
- Resistant to water, salt water, alkalis, most of the common chemicals, vegetable, lubricating oils and fuels.
- Performs well in a temperature ranging from –20⁰C to 80⁰C.
- Movement joints up to ± 25% of the width & Excellent repair-ability property.
- Slip resistant (non-sag) can be applied in vertical & ceiling joints.
- Resilient. Recovers the original width after expansion & contraction without losing the surface bond.
- Non-toxic, it can be over coated by waterproofing compounds.
Typical Application:
- Sealing of expansion, contraction & construction joints in building structures such as, basements, subways, retaining walls, floors, external walls and claddings of high-rise buildings, roof terraces & ceilings especially structural expansion joints running through the ceiling.
- Sealing of dynamic structural cracks, sealing of joints in traffic areas and car parking areas.
- Joints & ‘J’ bolts of asbestos sheet roofing.
Properties:
