Fosroc Joint Sealant Colpor 200PF

Cold applied, high performance, pitch free, polyurethane pavement joint sealant.

Description:

Joint Sealant Colpor 200PF cold applied, pitch-free, two part polyurethane sealant is designed for joints in concrete paved areas.The capability of accommodating cyclic movements is retained by Colpor 200PF throughout extremes of temperature conditions.Joint Sealant Colpor 200PFis resistant to fuel, oil and hydraulic fluid spillage, will not harden in cold weather nor become excessively soft or pick up in hot conditions. Joint Sealant Colpor 200PF has high durability and long service life which significantly reduces maintenance costs.

Uses:

For sealing and maintenance of horizontal joints in concrete roads, concrete runways and hard standings. The excellent fuel resistance of Joint Sealant Colpor 200PF makes it particularly suitable for sealing areas where fuel and oil spillage might occur such as:

• • Aircraft fuelling areas
  •  Oil terminals
  • Garage forecourts
  • Parking and cargo areas
  • Docks and harbours
  •  Warehouses

Advantages

• • • Pitch free - environmental friendlly
    • Cold applied - no heating equipment required
    • Fuel, oil and hydraulic fluid resistant
    • Self-levelling
    • Tough rubbery seal
    • High performance - less maintenance

Specification:

Where so designated on the drawing, joints are to be sealed using Fosroc Colpor 200PF, pavement sealant manufactured by Fosroc to BS 5212: 1990 and U.S.Federal Specification SS-S 200E:1984. Joints shall be prepared and the sealant mixed and applied in accordance with the manufacturer’s current data sheet.

Design Criteria:

Joint Sealant Colpor 200PF has a movement accommodation factor of 30% in butt joints. In designing joint spacing and dimensions, consideration should be given to the likely uneven distribution of movement.To ensure the sealant operates within its stated movement capacity of 30%, the width of sealing slots should be designed in accordance with the recommendations of IRC-57-2006. In trafficked areas the expansion joint width should not generally exceed 30 mm - for wider joints consult local Fosroc office.Joint depth: In trafficked areas the sealing slots should be constructed so that at no time during the anticipated operating cycle of the joint will the sealant protrude above the surface of the concrete pavement. It is necessary to recess the level of the sealant 5 to 8 mm below the pavement surface, dependent on the time of year and temperature prevailing at the time of sealing.The width to depth ratio of the Colpor 200PF seal should be 1:1 to 1½:1 subject to a minimum 10 mm depth of sealant (example, contraction joint: 15 mm wide x 13 mm depth; expansion joint: 25 mm wide x 20 mm depth).

Instructions for use Joint preparation

Joint Sealant Colpor 200PF slots in concrete should be accurately formed and must be dry, sound, clean and frost free. Remove all dust and laitance by grit blasting or grinding. Avoid polishing the joint sides when grinding. The prepared sealing slot should be blown out with dry, oil-free compressed air.Ensure that any expansion joint filler is tightly packed in the joint and at the required depth to provide the seal dimensions specified. Before sealing, insert a bond breaker caulked tightly into the base of the sealing groove to prevent the sealant from adhering to the base of the slot.

Priming:

Prime sealing slot surfaces with Primer No. 20 using a clean dry brush.Joint Sealant Colpor 200PF must be applied between 30 minutes and 2 hours after priming, depending on climatic conditions. Joint Sealant Colpor 200PF must be applied when the primer has become touch dry, that is after the evaporation of the solvent, but before the primer film has completely reacted.If the primer film has become completely tack free, the surfaces must be reprimed before applying the sealant.If the primed areas are left unsealed overnight the primer film must be removed by grit blasting or grinding and the joint interfaces reprimed. Therefore, avoid priming more work than can be sealed within the time-scales above.Avoid over application of Primer No. 20, as this may cause puddles of primer to lie at the base of the sealing slot.

Mixing:

Drain totally the contents of the tin containing the curing agent into the large base component tin. Using a hand held, slow speed drill (400 to 500 rpm) fitted with a Fosroc paddle blade stirrer, mix for approximately one minute, stop the mixer and scrape around the top of the tin to remove any remaining curing agent. Continue mixing for a further 3 minutes until the material is thoroughly mixed.

Application: Joint Sealant Colpor 200PF

When mixed, the sealant may be loaded into a Sealant Gun after removing the nozzle and cap and pulling back the plunger rod. The nozzle cap is then replaced ready for application.In wider joints of 25 mm and above, the mixed sealant may be poured directly from the tin by bending the side to form a pouring lip. Apply mixed sealant into the sealing slot so that the finished level of the seal is recessed below the trafficked surface as specified
