WHAT IS SEALANTS

WHY SEALANTS

Terminology – The Basics

BASE (Part –A) (High quality Polysulphide sealant) + Accelerator (Part – B) (Curing agent) ↓ IWL LIQUISEAL POLYSULPHIDE SEALANT (Flexible rubber like material)

Terminology – The Basics

Excellent adhesion ↓ Concrete, masonry, wood, glass, aluminum etc..,with the use of LIQUISEAL PS Primer. Capable of withstanding repeated extension, compression & Cyclic movements without loss of adhesion Resists deterioration by weathering, sunlight, ozone, water, salt,

• ils and fuels.

Mixing Process

Joint design

 joint - width: depth ratio 2:1  Total movement does not exceed the 25% MAF

 Wide 5 to 50 mm Depth - 5 mm for glass & metal

• 10 mm for porous surface
• 20 mm for joints exposed to traffic

and hydrostatic pressures

 Use backup material to adjust width depth ratio

 Masking tape on both side – uniform appearance

Vertical Applications

Coverage

Calculate the sealant weight (in kgs) for a joint of particular length (in meters), The following formula can be used. Weight in kg = SG × W × D × L 1000 SG = Specific gravity of the sealant W = Width of joint (mm) D = Depth of joint (mm) L = Length of the joint (metre)

Where we Apply

 High – rise and low –rise commercial buildings  Window perimeters, Roofing terminations, Expansion joints and butt-Terminations.  Internal and external wall claddings ,Plaza decks  Water retaining structures – reservoirs ,dams ,canals ,etc…..  Airport pavement runways  Bridge & Highway joints  Commercial parking lots and flat work
