Tests for Physical and Mechanical Properties:

• Mechanical testing, including tensile, flexural, sheer, and compression metrics.

• Physical testing, including density, hardness, scratch, and abrasion resistance. 

• Thermal testing, including DSC, DMTA, TMA, TGA, HDT, and Vicat Softening Points.

• Rheological tests, including capillary, rotational, Melt Flow Rate/Index and DSV.

• The barrier to ingress/egress, including Water Vapor Transmission Rate (WVTR), Oxygen Transmission Rate (OTR), and various gases.

• Weathering and Chemical Resistance testing, including UV, temperature, humidity, repeated sterilization, and environmental impact.

• Adhesion property testing.

• Flammability testing to various industry standards. 

• Optical tests, including color, color loss, clarity, haze, and gloss.

 

VOC ProShield™  meets or exceeds all expectations in the following areas:

• Strong and durable adhesion– Coating must bond permanently to all surfaces of the crumb rubber.

• Surface hardness – Coating should rate high on the hardness scale & resist all forms of daily wear and abrasion.

• Water ingress – An ideal barrier will allow little or no moisture to pass through the coating film – in or out. 

• Chemical resistance – Coating should be impervious to all chemical exposure, from solvents to fuels, alcohol, oil, urine, etc.

• Elongation (elasticity modulus) – Coating should stretch as much as the substrate without splitting or tearing.

• Thermal resistance –barrier film should withstand extremes of temperature – far over average winter/summer highs and lows.

• Weathering –daily exposure to direct sunlight, particularly UV rays, should cause no damage to the surface chemistry.

• Color fix –coating should contain coloration/pigment that is resistant to fading or discoloration.

• Application –Coating must be easy to apply and deposited in layers of uniform thickness.

• Mold/Bacteria free –Coating should not allow or promote the growth of biological that might break down the material.

• Toxicity – Coating should be safe enough to ingest (including dermal contact and inhalation) and produce no ill effects to humans, pets and plant life – even following prolonged contact.

 

The VOC ProShield Advantage:

• Blocks VOC, SVOC (volatile organic compounds)

• Blocks leaching (metals) from soil and water

• Long-lasting barrier (20-year durability warranty)

• Color resists fading (20-years color and voc-lock)

• Safe on athletic fields, playgrounds, schoolyards, gardens, animal bedding, and other uses.

 

Thermal Properties:

ProShield can function continuously at temperatures as high as 250F (125C), at least double what it will encounter in the field. Tested in extreme temperatures as low as -80F (-60C).  In both cases, there were virtually no adverse effects on the coating.

 

Gas & Moisture Permeability (cc-mil/100 in. 2 – 24 hrs):

Gas and Moisture permeability are amongst the most critical tests relative to assessing the effectiveness of a coating concerning the long-term release of harmful organic compounds in the air (VOC, SVOC, PAH) and leaching of hazardous compounds and metals to the soil (cadmium, zinc, lead, others). VOC-ProShield, in terms of water permeability, was proven to be twice as effective as Silicone, a powerful and well-documented barrier film. For other materials, ProShield was over 100 times more effective. If gases and moisture cannot easily penetrate the ProShield coating from the outside, then harmful compounds cannot easily escape from the inside.  

 

Impact Resistance:

Much of this characterization of the material is reflective of a 3-4 mil film thickness. This equates to roughly 75-100um (microns). At the 125um level, the VOC-ProShield™ has an impact value of 50kg/cm and the Epoxy; a super hard and brittle material is 50. Note that epoxy is also used occasionally to resurface garage floors and even create kitchen counters. Epoxy, however, is brittle, while ProShield is pliable and can resist impact and compression for a more sustained duration. 

 

Resistance to Chemicals:

VOC-ProShield™ demonstrates superior properties as barrier chemistry against ingress and damage from a wide range of chemicals. Virtually everything that might come in contact with the coating, whether in athletic fields or playgrounds and landscapes, is considered and evaluated here. Primary attention is given to those materials that could potentially be applied as a fertilizing chemical or as an accidental spill (as in the case of fuels and lubricants from vehicles and gardening tools). When compared to acrylic, the superiority of the VOC-ProShield™ is far superior. 

There are close to 200 well-defined toxins, carcinogens, or other potentially harmful compounds and metals in recycled tires. Discussion and debate are relative to precisely what amount of exposure to these chemicals and what constitutes a health risk are still ongoing.

 

Our team of experts at VOC-ProShield™ has instead opted to take this position:

 

“We have the means and the technology to take the guesswork out this equation.  Reducing exposure means mitigating risk to health and the environment.  Defining dose, exposure, and impact on health is an argument we shouldn’t even be having."
