ROCKSEAL 6600P
DESCRIPTION
ROCKSEAL 6600P is a two component Polysulphide sealant. It is used for sealing expansion joint sealantwhere large movement is anticipated in concrete construction and for joints between diverse construction materials like glass, aluminum, steel, cladding, glazing, tiling, tanks, internal and water retaining structures. It is used for sealing of expansion joints where there is vehicular traffic (e.g. airports and bridges) or pedestrian traffic. After mixing Resin and Hardener, the polymerization is initiated at room temperature, which proceed further until it is cured.
It has superior joint movement accommodation with strong adhesion to most building material. It is chemically resistance to water oils solvents

DIRECTIONS FOR USE
METHOD OF APPLICATION
The product may be applied to joint between 5 to 50 mm wide. Joints subjected to cyclic movements sho designed for an optimum width/Depth ratio of (W = 2D)
Minimum joint depths are:
5mm for metals, glass and other non – porous surfaces.
10mm for all porous surfaces like brick and concrete.
20mm for trafficked joints and those subject to hydraulic pressures
Hardener is mixed with Resin and stirred gently to get uniform color mix. Prior to the application of the sealant all joint surfaces should be thoroughly cleaned and dried and primed with suitable primer. Primer promotes strong adhesion of the sealant to the surface and is absolutely essential on most surfaces. Primer should be brushed on the sides of the joint. ROCKSEAL 6600P have excellent adhesion of the joint. In order to get maximum adhesion to surface of construction,
STORAGE AND SHELF LIFE
The Resin and Hardener should be stored at a temperature not exceeding. At higher storage temperatures the storage life would decrease sharply. The Resin and the Hardener containers should not be exposed to sunlight to avoid gelation.
Shelf life is 12 months from the date of manufacture in unopened containers PACKING
3680 Gms Resin in 4 liter wide mouth tin container.
320 Gms Hardener in 250 ml plastic cover
PRECAUTIONS
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
