Hot Poured Fuel Resistant Joint Sealant
Estoseal E77 single component hot poured joint sealant is designed for sealing joints in concrete pavements, airfield aprons, cargo terminals, warehouses and parking areas.
It possesses good adhesion to concrete and asphaltic materials. Estoseal E77 is suitable for immersed joints, including low movement expansion joints, floor joints of reservoirs, basement etc.
Estoseal E77 is used for sealing joints in:
|Movement Accommodation Factor||25% for butt joint|
|Shore A Hardness||> 15|
|Density, kg/L||1.1 – 1.3|
|Flash Point, oC||Min 200|
|Softening Point , oC||85 – 105|
|Application Temperature, oC||Over 5|
|Pouring Temperature, oC||160 – 180|
Chemical Resistance to Occasional Spillage
Roads and traffic surfaces: Estoseal E77 compounds are particularly recommended for sealing joints in reinforced and un- reinforced concrete roads and airfield runways. Since they are bituminous compounds, they are suitable for sealing against bituminous asphalt surfaces.
Water retaining structures: Estoseal E77 compounds are recommended for sealing horizontal joints in many types of water retaining structure, including floors and roofs, swimming pool substructures and irrigation canals, reservoirs, treatment plants, box culverts etc.
The joint surfaces shall be dry and free from old sealing compound, dust, scale grit, laitance and loose stones. New concrete surfaces shall be cured before compound is poured. Where applicable, care must be taken to ensure that compressible filler such as Estocell will provide adequate support for the Estoseal E77 compound. Absorbent surfaces, such as concrete and brickwork, need to be primed after the surface being torch with gas and still warm to ensure satisfactory adhesion.
Use Estop Primer S1 on concrete, stone and brick paving. Allow to become touch dry before sealing, normally 1 to 4 hours.
Metal surfaces do not require priming but should warm to ensure satisfactory adhesion. Ferrous metal should be treated with an anti-corrosion primer.
It is essential that the correct equipment be used for re-melting Estoseal E77 to ensure that the subsequent performance is not impaired by damage through overheating or pouring at the wrong temperature. The heating apparatus must be equipped with a thermometer, an oil jacket and a means of stirring the molten compound. Direct heating should be limited to low flame and equipment fitted with a mechanically driven stirrer.
Note: For small jobs, Estoseal E77 may be used with a small, directly heated vessel, but great care must be taken to avoid over heating the Estoseal E77 compound. In these cases, limited quantities of material should be cut up into small lumps and melted gradually in the molten mass whilst stirring.

Estop offers a technical support package to specifies, end-users and contractors, as well as on site technical assistance.
Estoseal E77 should be stored on pallets in dry conditions. Under these conditions, the product will have a shelf life of 24 months.
If stored in extreme heat locations the shelf life may be reduced.
There is no known health hazards associated with Estoseal E77. Do not melt the compound in confine space, as concentrated fume may be injurious. Do not exceed safe heating temperature.
Estop Primer S1 is a highly flammable liquid. It should be kept away from sources of ignition. Wear suitable protective clothing, gloves and eye/face protection.
Estop manufactures and offers a wide range of complementary products, which includes waterstops, waterproofing products, grouts, anchors, specialized flooring products. In addition, a wide range of products formulated for repair and refurbishment of spalled concrete are available.
