PRO-POXY(TM) 50-1 is an extremely low viscosity, solvent-free, two-component epoxy healer-sealer and primer designed both for the protection of new concrete and for the preservation of partially deteriorated concrete to extend its service life.
PRO-POXY(TM) 50-1 is thin enough to completely penetrate cracks, yet has sufficient rheology to leave no starved glue lines. It meets ASTM-C-881 Types I, II, IV & V, Grade 1, Classes B & C for load-bearing applications. PRO-POXY(TM) 50-1 is an excellent alternative to dangerous methacrylates.
Compliances
ASTM-C-881: Types I, II, IV & V, Grade 1, Class B, C
Features
Economical – more cost-effective than methacrylates
Safest – nonflammable, nonexplosive
Best performance – moisture insensitive, ultra low viscosity, high bond strength, meets ASTM-C-881 specifications for load-bearing applications
Extended shelf life.
Structurally restores integrity of concrete
Super low viscosity
Quality assurance with Z18 fluorescent tracer dye With only 10 psi, rebonds cracks too small to see.
Core samples fluoresce under black light for proof of penetration.

Application
 |
STEP 1. Patch deteriorated concrete with Unitex PRO-POXY(TM) 2500.
|
 |
STEP 2. Clean surface by abrasive blasting.
|
 |
STEP 3. Mechanically mix component A with component B at 2:1 by volume with a Jiffy type mixer and variable speed drill at 300 rpm for a minimum of 3 minutes.
|
 |
STEP 4. Immediately flood-coat PRO-POXY(TM) 50-1 onto concrete.
|
 |
STEP 5. Distribute evenly and work into concrete for minimum of 5 minutes for maximum penetration. Keep ponding PRO-POXY(TM) 50-1 into cracks until refusal. Remove all excess with a squeegee on smooth surfaces and a broom on textured surfaces.
|
|
Surface should appear damp but with no film buildup or ponding prior to broadcast or subsequent overlay.
NOTE: If used as a primer, proceed with overlay application while PRO-POXY(TM) 50-1 remains tacky.
|
 |
STEP 6. For healer-sealer application, broadcast oven-dried silica sand to refusal. After initial cure, remove excess sand.

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
Component B - Corrosive
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.
