Duflex PS - 600

TWO PART POLYSULPHIDE ELASTOMERIC SEALANT

Dubond’s Duflex PS - 600 is a two part elastomeric sealent based on 100% solids liquid polysulphide polymer. Which when the components are mixed together, cures to form a hard wearing flexible rubber seal for use in vertical or horizontal joints.It consists of a‘Base’ compound and ‘accelerator’ (Curing Agent). When the two components aremixed together prior to application, a chemical reaction is initiated which cures instant to a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood,glass, acrylic and PVC plastics.

Duflex PS - 600 cures at normal temperature to a tough elastomeric seal, which will adhere tenaciously to concrete, masonry, stone, ceramics, metal and wood. Duflex PS -600 will withstand repeated expansion and contraction and remain resilient through daily and seasonal cyclic changes in temperature. It has excellent chemical, solvent, and water resistance. It complies to BS 4254, ASTM C 920 & US Federal Specification TT-S-0027E. It is capable of withstanding repeated extension, compression & Cyclic movements without loss of adhesion and resists deterioration by weathering, sunlight, ozone, water, salt, oils and fuels.

  • Packaging
  • Storage Life
  • Excellent chemical, solvent, and water resistance
  • Forms a tough elasti rubber-like seal
  • Accommodates continuous and pronounced cyclic movement
  • Excellent adhesion to most common substrates
  • High resistance to aging influences,physical damage and climatic extremes
  • 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, 10% dil. Acids except nitric acids, alkalies, most of the common chemicals,Vegetable, lubricating oils and fuels.
  • Performs well in a temperature ranging from –20C to 80C.
  • Slip resistant (sag) can be applied in a horizontal joints.
  • Movement capability – provides satisfactory hermetic sealing of the joint subjected to expansion, contraction,
  • Vibration and cyclic movement within the following limits. - movement joints upto + 25% of the width.
  • Slip resistant (non-sag) can be applied in vertical & ceiling joints.
  • Self leveling, after pouring in horizontal joint levels itself.
  • Resilient recovers the original width after expansion & contraction without the loosing the surface bond.
  • Excellent repairability property it can be overcoated by waterproofing compounds.
  • Non-toxic sealant will not cause staining to concrete masonry or stones.
  • Designed for ceramic floor and wall tiles for out door and in door.
  • Expansion joints in most building super structures roofs, walls etc.
  • Glazing frames windows and in curtain walls.
  • Bridge decks,subways and heavily trafficked floor joints.
  • Basements and retaining walls.
  • Floors where high movements, load displacement and chemical resistance is required.
  • Water retaining structures such as swimming pools, reservoirs, dams, canals, culverts and water treatment works.
  • Fill the top portion of the joint with Polysulphide two pack sealant used within the specified time of mixing.
  • This is particularly critical and no attempt should be made to remix or thin out half set material using solvents to make it to application viscosity since the viscosity increase is due to an irreversible reaction.
  • Ensure that two people are on the job at one time, one of them filling in the joint and the other simultaneously tooling the same to give the top of the same a concave appearance.
  • Both the filling and the handling should be done by dipping the hands or tools in kerosene continuously as otherwise the material will stick to the hand or the tools and therefore be difficult to handle. Also Soap solution can be used to smoothen the sealant surface other than the use of kerosene.
