Application
1. SURFACE PREPARATION: Substrate must be free of oil, grease, and other contaminants. Steel surfaces should sandblasted to white metal finish. Sharp edges should be smoothed.
2. FORM: Open cell foam should be compressed between the frame
and foundation to construct a water-tight form. Foundation bolts and
jacking bolts should be wrapped with a 1/8” layer of weather stripping
or neoprene foam. All forms must be coated with release agent or
paste wax. Check the chock area for any possible locations that could
cause a leak. MACHINERY MUST BE IN FINAL ALIGNMENT
POSITION PRIOR TO POURING PRO-POXY(TM) CHOCK.
3. MIXING: Resin and hardener should be conditioned to between 18o C (65oF) and 29oC (85oF) for at least 12 hours before use. Pour Part B into the Part A container and mix thoroughly for 3 to 4 minutes with a low speed drill at 200 rpm. Keep the mixer completely submerged to prevent air entrainment. Remove material completely from around the sides and bottom of the container with a spatula to ensure a complete and uniform mix.
4. POURING: Always pour PRO-POXY(TM) CHOCK from the lowest side of the chock area which will force air to escape through the opposite corner. Continue to pour slowly until the entire chock area is filled and the chock overpour area is filled to a level approximately 12 mm (1/2 inch) above the bottom of the bedplate.
|
Limitations
For pour depths less than 12 mm (.5 inch) or greater than 76 mm (3 inches) contact Unitex technical support. Minimum application temperature 50oF. Do not thin. Solvents will prevent proper cure.
|
Cleanup
Ventilate area. Confine spill. Collect with absorbent material, flush area with water. Dispose of in accordance with current applicable local, state and federal regulations. Uncured material can be removed with Unitex CITRUS CLEANER or other approved solvent. Cured material can only be removed mechanically.
|
First Aid
EYE CONTACT: Flush immediately with water for at least 15 minutes. Contact physician immediately.
RESPIRATORY CONTACT: Remove person to fresh air.
SKIN CONTACT: Remove any contaminated clothing. Remove epoxy immediately with a dry cloth or paper towel. Solvents should not be used as they carry the irritant into the skin. Wash skin thoroughly with soap and water.
CURED EPOXY RESINS ARE INNOCUOUS.
|
Cautions
Component A Irritant: Prolonged contact with skin may cause irritation. Avoid eye contact.
Component B Corrosive: Contact with skin may cause severe burns. Avoid skin contact.
Product is a strong sensitizer. Use of safety goggles and chemical resistant gloves are recommended.
Use of a NIOSH/MSHA organic vapor respirator is recommended if ventilation is inadequate.
Avoid breathing vapors. Avoid skin contact.
