CM 200 PF fast cure

CM200 PF FAST CURE can be used for sealing expansion joints in concrete paved areas, docks, container depots, industrial factories and warehousing. CM200 PF FAST CURE is high adherent to most materials commonly used in Fuel garage forecourt construction. It is cold applied and is therefore economic to use on small run jobs – in particular remedial re-sealing of joints in busy areas such as loading yards and hard-standings where specialised application equipment for hot applied sealants would normally be required.

Advantages

• HIGH PERFORMANCE Good movement accommodation, tolerant of severe climatic conditions.
• CHEMICALLY RESISTANT Resistant to spillages of fuels, hydraulic fluids, synthetic and mineral oils, and dilute acids and alkalis.
• EASY TO USE Hand pour or machine apply to suit joint size.
• NON TOXIC Contains no pitch or related ingredients.
• RELIABLE ISO 9002 Quality Assured Firm.

Cure Times:

The pot life is 20 to 30 minutes at 25C and tack free time is 3 hours. However, the application time and rate of cure will depend upon the temperature of sealant and the ambient temperature at the time of application. At higher temperatures, the rate of cure will be faster. Final cure, when full working properties are developed, occurs within two days at 25C, although the sealant will normally bear traffic with 36 hours of application. Low temperatures retard cure. Do not apply at temperatures below 4C.

Typical Test Results at 20C

Complies with the requirements of:

• 1 BS5212. 1990 Type N.
• 2 ISO 11600-F-25LM

Shore Hardness: Using Shore Durometer A2, the hardness of CM 200 PF FAST CURE is 17.
Movement Accommodation Factor: +/- 25%

Method Of Use

Preparation of Substrate

All joints should be completely dry and free from all traces of dirt, dust, grease, and previous sealants and other foreign matter. Cleaning may be carried out by sand / grit blasting, grinding, sawing or water jetting, depending on new or re-sealing applications. Wire brushing must only be used for the removal of filler boards. In all cases, a clean bonding surface must be obtained.
In re-sealing situations, where joints have been previously sealed with pitch based material and traces of bitumen are still present, our Technical Service Department will advise on the most suitable method of preparation and priming. Joint sides must be parallel and straight. Spalled joints should be repaired with an appropriate material, such as EPOXYPATCH FAST CURE.
Following preparation, place into the base of the joint a bond breaker or BACK UP FOAM to form the correct cross section for the joint sealant and to prevent the sealant bonding to the base of the joint.

Priming

After cleaning the joint faces should be primed with the appropriate primer, care being taken to ensure complete coverage.
Porous Surfaces, ie. concrete and other cementitious materials, timber and epoxy nosings, use PRIMER C
After priming allow half an hour for the solvent to evaporate. If application of CM200 PF FAST CURE is delayed for more than 2 hours after priming, joints should be re-primed.
Non-porous and Damp Surfaces: Optimum performance will be achieved by sealing joints that are dry. But where unavoidable, damp (not wet) joints may be sealed using the following primer system. Use EPOXY GP PRIMER. This primer is supplied in two tins marked A and B. These must be thoroughly mixed together and applied by brush as soon as possible after mixing. Care must be taken to ensure a 100% coating/membrane is formed over the prepared substrate before applying the sealant. Pot life is approximately 1/2 hour depending on temperature. Allow the GP Primer to initially cure (12 to 24 hours)
It is important that for optimum performance of CM200 PF FAST CURE the correct primer is used.

Mixing and Application

Stir the contents of Pack B and add the entire contents to Pack A and stir for a full five minutes, preferably using a slow speed electric drill (max 500 r.p.m.) with a mixer paddle, until a completely homogeneous mix is obtained. Take care to avoid including excess air. Mixing is made easier if the Pack B is added and mixed in two stages. Pour or gun apply immediately into the primed joint. Current practice requires that the sealant shall be poured to a level between 3mm (Summer) and 6mm (Winter) below the wearing concrete surface. (Contact our Technical Services Department for details of bulkfill gun equipment).

Cleaning of Tools

Tools and equipment should be cleaned with CM Multi wipes as soon as possible after use.
