SKU: PROPOXY-LWT Categories: ,
ProPOXY LWT is a long working time version of the ProPOXY 3:1 epoxy coating system, engineered for projects requiring extended application windows. It combines ProPOXY S Resin with the LWT-Hardener to deliver a slower curing, high-performance coating suited to ProLumina systems or large surface areas. This low odor, 100% solids system is compliant with USDA, FDA, and EPA VOC standards. The mix ratio is 3 parts resin to 1 part hardener, with optional field tinting using ProColor Universal Colorants. Applications include clean rooms, laboratories, and commercial spaces where additional working time is necessary for precision or coverage.

STORAGE

Materials should be stored indoors between 60°F (16°C) and 90°F (32°C).

SHELF LIFE

One (1) year from date of manufacture.

LIMITATIONS

This product is best suited for application in temperatures between 45°F and 90°F. Epoxy is light-sensitive to ambering over time, and requires a UV stable topcoat. Some light colors may require multiple coats for adequate hiding power. Certain colors appear white when scratched. Slight batch-to-batch color variations may occur. When ordering to match a previous color, inquire if the same batch number or quality control number is still available.

PRODUCTS GUIDE

1. ProPoxy S Resin is a well-rounded and versatile 3:1 epoxy to be used as a primer, body, self-level, or grout/top coat. When used as a self-level system ranging from 30-100 mils, combine with ProFill SL Filler.  

2. ProPoxy Cove Resin is a thickened and versatile 3:1 epoxy to be used as a vertical primer and binder when mixed with silica quartz aggregates. Can also be used as a grout coat over epoxy troweled mortars and to repair non-moving control joints & cracks.

3. ProPoxy S-Hardener is a versatile epoxy hardener that balances longer working time with an 8 hour cure (70°F) when combined with ProPoxy Resins.

4. ProPoxy F-Hardener is an accelerated hardener when combined with either ProPoxy resins. It is designed for quicker turn-around and recoat with 4 hour cure time (70°F).

5. ProPoxy LWT-Hardener is a long working time hardener when combined with ProPoxy resin. It is designed specifically for ProLumina systems requiring extended “open” time.

COVERAGE RATE

A gallon of ProPoxy will cover in the following manner, with a *standard spread rate: 6-20 mils or 80-267 s.f. per gallon. *Application of primer, body, and topcoats are variable in thickness depending upon condition of substrate and type of system.

PRELIMINARY FLOOR INSPECTIONS

CHECK THE CONCRETE: Concrete must be structurally sound and free of curing membrane, paint or other sealer. If you suspect that the concrete has been previously sealed, call ProREZ technical support for further instructions.CHECK FOR MOISTURE: Concrete must be  dry before application of ProREZ floor coating materials. Concrete moisture testing must occur. Calcium chloride testing or in-situ relative humidity testing is recommended. Test methods can be purchased at  www.astm.org, see ASTM F1869-11 or  F2170-11, respectively or follow manufacturer’s instructions. Readings must be below 6lbs/1,000s.f./24hrs (ASTM F1869-11) or  82% internal relative humidity (F2170-11). *Note: Although testing is critical, it is not a guarantee against future problems. This is especially true if there is no vapor barrier or the vapor barrier is not functioning properly and/or you suspect you may have concrete contamination from oils, chemical spills or excessive salts.CHECK THE TEMPERATURE AND HUMIDITY: Floor temperature and materials should be between 55ºF and 85ºF. Humidity must be less than 95%. DO NOT coat unless floor temperature is more than five degrees over  the dew point.

SURFACE PREPARATION

This product requires preparation in order to perform as expected. Substrate must be mechanically profiled (ASTM 4259-83), clean, sound, and dry.

JOINT GUIDELINES

Depending on preference, joints may or may not be filled. If the joints are filled, nonmoving joints, i.e. contraction or control joints can be treated by using ProPoxy with ProThickeneror by using ProUrea HF, a hard-and-fast urea filler for Fast-Track applications.Note: Coating applied over filled joints may crack if there is concrete movement.

MIXING INSTRUCTIONS

Application Equipment:

  •  Personal Protective Equipment (PPE) & clothing per SDS (Safety Data Sheet)
  •  Jiffy® Mixer Blade (ES Model)
  •  Clean Mixing Container
  •  Low Speed /High Torque Power Drill
  •  Shed-Resistant Roller Cover- 3/8" Nap
  •  Application SqueegeeMix ratio for ProPoxy is 3 parts Resin to 1 part Hardener by volume. 8-16 oz. of ProColor Universal Colorant is recommended per gallon of material. (See product label.) When field pigmenting, it should be added and mixed in homogenously to the resin prior to adding the hardener.  When combining, be sure to add the hardener into the clean mixing container first. Then add the resin (clear or pigmented) scraping out the container. Always pour into the center of the mixing container. Mix the components thoroughly for 1-2 minutes with a Jiffler ES style mix blade. Mix only enough material at one time that can be applied without exceeding the pot life.CLEANING GUIDELINES  & MAINTENANCEAllow floor coating to cure at least 3 days before cleaning by mechanical means (e.g., sweeper, scrubber, disc machine).

CARE

Proper maintenance will increase the service life and help maintain the appearance of your new ProREZ floor coating system. This product is considered to be a low maintenance coating system, however, certain textures and service environments require specific procedures. SEE “CLEANING GUIDELINES” for more information.

CAUTION

Avoid scratching or gouging the surface. All floor coatings will scratch if heavy or sharp objects are dragged across the surface.

Do not drop heavy or pointed items on the floor as this may cause chipping or concrete pop-outs in the case of a weak substrate cap.

Rubber tires can permanently stain the floor coating from plasticizer migration. In warehouse & industrial settings, the use of non-marking tires is highly recommended to prevent discoloration. Rubber burns from quick stops and starts can heat the coating to its softening temperature, causing permanent marking.

REPAIRS

Repair gouges or scratches or chip outs as soon as possible to prevent moisture or chemical contamination.

DISPOSAL

Dispose in accordance with federal, state and local regulations.
