Foster® Chil-Lock CP-240 Asbestos Removal Agent/Post Removal Sealer

• Foster® Chil-Lock CP-240  is an economic, fire retardant, polymeric water-based asbestos removal agent and post removal sealer.
• As a post removal sealer, it is designed to mist, lock down, and seal free asbestos fibers and residual asbestos containing material (ACM) after removal.
• It effectively locks the ACM onto cleaned, exposed substrates and polyethylene sheeting within the containment area to prevent any loose fibers from becoming airborne.
• It adheres to structural steel and surfaces to be reinsulated for service temperature applications up to 250ºF (121ºC).
• It is also used as a primer on structural surfaces to be fireproofed in respray applications.
• Foster® Chil-Lock CP-240 may also be used in a diluted form as an asbestos removal agent to mist and wet ACM for removal purposes in the containment area.
• Foster® Chil-Lock CP-240 asbestos removal agent/post removal sealer is waterbased and contains no harmful solvents.
• It has no objectionable odor and does not adversely affect workers in the containment area or in areas adjacent to the abatement operations. Application is quick and easy.
• Foster® Chil-Lock CP-240 contains no asbestos, lead, mercury, or mercury compounds.

Material preparation

• Stir well but do not use sticks, boards, or anything else which would splinter or otherwise contaminate the product.
• If Chil-Lock CP-240 is to be diluted for the removal of asbestos containing materials, insure that the dilution vehicle and the mixing container are free of any contaminants that could in any way impair the performance of the resultant mixture or the spray equipment.

Site preparation 

• As a minimum, follow all procedures outlined by Federal, State, and Local Authorities regulating asbestos abatement projects and the wastes generated therein.

Application 

• For Removal of ACM: Chil-Lock CP-240 may be diluted up to 4 parts water to one part product (if desired).
• Mist the containment area to minimize airborne asbestos contaminants, and then wet all ACM surfaces lightly to break the surface tension.
• Then, spray the ACM until droplets begin to form on the surface. Allow the product to “wick in” to the ACM while continuing to spray adjacent ACM surfaces.
• Continue to spray apply until maximum penetration has been achieved. ACM must be removed while still wet.
• For Post Removal Encapsulation (Lockdown):
• Chil-Lock CP-240 must be applied as supplied by the manufacturer.
• Do not thin or dilute, since various approvals from other manufacturers may be affected, or even nullified, which may result in a voided product warranty.
• Apply the product by airless spray.
• First, mist the containment area to entrap and seal residual asbestos fibers remaining in the air.
• Then continue application onto the exposed substrates to lock down and seal residual and/or free asbestos fibers remaining in the containment area, after the preliminary removal work and final inspection has been completed.
• Allow to dry thoroughly overnight before taking final fiber count readings, and before approval to disassemble the containment area.
• Spray Equipment: Chil-Lock CP-240 asbestos removal agent/post removal sealer is normally applied by low pressure airless spray equipment.
• It may also be applied by brush or roller to surfaces not receptive to spray application.
• Pressure settings for airless spray application should be kept to minimum levels while maintaining adequate atomization during application.
• Glove Bag/Hand Pump Application:
• Place a full hand pump sprayer into a glove bag with other necessary tools, and install the glove bag per manufacturer’s recommendations.
• Spray apply the Chil-Lock CP-240 asbestos removal agent/post removal sealer onto the ACM to lock down friable fibers.
• Mist and wet the entire surface inside the glove bag before removing ACM.
• Remove all ACM in accordance with specifications.
• FLOORS CP-240 is not suggested as a floor traffic coating.
• It may be used on floors provided that a new floor surfacing material is installed over it.
• Flooring installers must determine by their own tests that any mastic, adhesive or cement they plan on using is compatible with, and bonds firmly to, the dried CP-240.

Clean up

• Use fresh water to clean equipment before the product dries.
• Dry product may be removed with hot soapy water or strong solvents such as chlorinated solvent (non-flammable) or xylol (flammable).
