3.ISO9000 Certificate

Description:

 

LangWei® 503 is a two-component polusulphide based joint sealant basically for sealing horizontal and vertical movement joint in concrete and pavements. When the two component are mixed and it forms tough, flexible durable rubber with strong adhesive property on most building substrates and joints 

 

Advantage:

  1. Two component polysulphide rubber
  2. High resilient with excellent recovery characteristics
  3. Permanent and uniform watertight seal
  4. Used for concrete cracks, highway pavement, Airport runway, reservoir and more
  5. Excellent resistance to fatigue and stays flexible throughout its service life-won’t become brittle, caulk or crack due to ultra violet exposure
  6. Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes
  7. Excellent adhesion to most common building substrates
  8. Good resistance to ageing. Retains joint soundness once cured
  9. Resistance against mild chemicals, hydrocarbon fuels, sea water
  10. Non-toxic, can be used in potable water applications, swimming pools and tank

 

Field of application:

 

1. Sealing of movement and flexible joints

2. Structure floor joints

3. Airport runway and apron pavement

4. Industrial warehouse

5. Garages & workshops

6. Swimming pool floors

7. Tank and reservoirs

8.Underground project( Tunnel, Sewer) and Subway

Joint Size:

 

Joint size may range from a minimum of 5mm to a maximum of 50mm wide. Joint with cyclic movements should have a width: depth ratio of 2:1 and designed so as total movement does not exceed the 25% MAF related to the joint width.

Sealant depth shall not exceed joint width

 

Minimum sealant depth recommended

  • 5mm for metals, glass and other impervious surfaces.
  • 10mm for all porous surfaces.
  • 20mm for joints exposed to traffic and hydrostatic pressures.
  • 5mm below flush for joints exposed to traffic.

 

Joint Preparation:

 

Surface

Treatment

 

Concrete & Masonry

Surface must be clean and dry. Wire brush thoroughly and remove dust and all contaminants

 

Metals

Remove any corrosion or millscale by grit or shot blast, wire brush, grinder or chemical remover. Degrease the surfaces with clean cloths soaked in oilfree cleansing solvent

Wood(bare)

Wood surfaces must be clean and dry. Cut back or abrade where necessary to sound timber

Glass and Glazed

Material

Thoroughly clean the surfaces with clean cloths soaked in oil-free cleansing solvent

Coated Surface

Where feasible, coatings should be removed and the surfaces treated as above

 

Packing Details:

 

6 small barrel in a carton, totally 25kg one carton, include 5 barrel A part and 1 barrel B part

 

Storage Life:

 

The storage life is at least 12 months, but the material should be used before the date stamped on the container. Storage temperature range is 5~35°C(41~95°F) in original unopened containers. Storage in dry conditions.
