SikaPronto®-500 PPC

6 months in original, unopened containers.

SikaPronto®-500 PPC resin, initiator and accelerator should be stored in a cool, dry location and in their original containers. All components should be stored out of direct sunlight and away from moisture. At elevated temperatures, storage shelf life is reduced. Store all bagged aggregates in a clean, dry location away from moisture. Aggregates must absolutely be protected from any moisture.

Approximately 120 cps.

Minimum ambient air temperature of 40°F (4°C). Maximum ambient air temperature of 95°F (35°C).

Initiator Cure Matrix

Recommended dosages of SikaPronto®-500 PPC resin are designed to have a neat resin pot life of approximately 20 minutes.

*For temperatures above 75°F(24°C), consider a night time application. Contact Sika Technical Services.

One 55 gallon drum of SikaPronto®-500 PPC resin yields approximately 31-34 ft³ of polymer concrete at a 12% resin load.

Yield is dependent on resin load. Allowance must be made for surface profile, unavoidable variation in applied film thickness, loss, and waste. Tined concrete, cracks, spalls, and pop offs will consume more material.

Mixing can be performed using a mortar mixer or volumetric mixing truck. Use appropriate measuring tools (i.e. syringes, pipettes, measuring cups) to properly dose SikaPronto®-500 PPC. Refer to Initiator Cure Matrix at the current ambient and substrate temperatures for the correct amounts of initator and accelerator (if needed).

For a 9 cubic foot mortar mixer, add 4 gallons of SikaPronto®-500 PPC Resin. Add the correct amount of Norox® MEKP-9 initiator to the mortar mixer. If needed, add the correct amount of DMAA accelerator to the existing resin mixture. Mix for approximately 2 minutes. While mortar mixer is turning with SikaPronto®-500 PPC Resin and initiator(s), add 2 x 50 lb bags of Stone Blend and 4 x 50 lb bags of Sand Blend. Dump mixed and catalyzed overlay/patching compound into a wheelbarrow to transport to application area. Immediately recharge mixer with proper volume of SikaPronto®-500 PPC Resin. Continue mixing procedure ONLY if crew is ready for another mix. Temperature and application timing have a definite effect upon set time of the polyester polymer concrete and the ultimate return to service. For any alterations to the mix design please consult Sika Technical Services.

Volumetric mixers may also be utilized for high output applications. The utilization of volumetric equipment is highly recommended for large overlay projects requiring rapid return to service.

Once the SikaPronto®-500 PPC is mixed it should be immediately placed onto the bridge deck. SikaPronto®-500 PPC should only be applied onto substrates primed with SikaPronto®-19 4K while the primer is still wet. For large areas, a vibratory screed or slip form paving machine can be used while hand finishing concrete tools can be utilized for smaller patches. After the SikaPronto®-500 PPC is compacted and finished, broadcast topping sand at a rate of 1-1.5 lbs/ sq.ft. and provide mechanical texture using spring steel tines. Typically, tines are 1/8" deep at a frequency of 3/4"-1". 

The agitating mortar mixer with SikaPronto®-500 PPC Resin only, without catalyst, will keep your mixer clean and reduce build-up. Once application is complete, mixers can be cleaned using appropriate solvents (e.g. Acetone, MEK, Xylene). Adding additional stone to solvent will aid in cleaning of any hardened material.
