INSTALLATION 59 Special care shall be taken to avoid contamination of TYCO CPVC Pipe and
Fittings. (See Notice located on Page 55, Chemical Compatibility section)
Handling - Solvent Cements
• CAUTION
Prior to using CPVC solvent cements, review and follow all precautions found on the container labels, material safety data sheet, and Standard Practice for Safe Handling ASTM F 402. Failure to follow precautions may result in injury.
Cements contain volatile solvents that evaporate rapidly. Avoid breathing the vapors and provide ventilation. If necessary, use a fan to keep the work area clear of fumes. Avoid skin contact. Keep the cement can closed when not in use. If the cement thickens beyond its original consistency, discard it. Do not attempt to dilute it with primer or thinner, as this may change the character of the cement and make it ineffective. Primers and thinners may also not be compatible with the TYCO CPVC and could cause failures. (See Notice located on Page 55, Chemical Compatibility section)
Before applying solvent cement, appropriate safety precautions should be taken. Cement must be stored between 40°F (4,4°C) and 90°F (32,2°C) and should be kept in the shade. Eliminate all ignition sources and do not smoke when using. Explosion proof general mechanical ventilation or local exhaust is recommended to maintain vapor concentrations below 4 recommended exposure limits. In confined of partially enclosed areas, a NIOSH approved organic vapor cartridge respirator with full face piece is recommended. Containers of solvent cement should be closed when not
in use. Wearing PVA coated protection gloves and an impervious apron are recommended. Splash proof chemical goggles are recommended. For further information refer to Technical Data Sheets TFP1990 SDS (Safety Data Sheet) for TFP-500 One Step Solvent Cement or TFP1994 SDS (Safety Data Sheet) for TFP-600 One Step Solvent Cement.
Note: TYCO’s CPVC solvent cement has a shelf life of approximately one to two years.
Storage - Solvent Cements
Cement must be stored between 40°F (4,4°C) and 90°F (32,2°C) and should be kept in the shade. Eliminate all ignition sources.
Solvent - Cement Spills
The best protection from accidental spills of cement is to protect the work area with drop cloths. If cement comes in contact with fiberglass tub/ shower enclosures, carpet or furniture, the excess cement must be wiped up immediately. Once the cement is dry, it is almost impossible to remove.
The use of solvents such as alcohol, M.E.K. or acetone will usually work on tile sinks or floors but can do more damage than good on some synthetic materials. Care should be used when trying any solvent to remove cement from any surface. Always protect the work area before starting, both under and around where cement spills can cause irreparable damage.
Whatever method is used, it should first be tested on a small hidden area, if it removes the shine or color or softens the surface, do not use.
