Products

LINE-X® chemists, using our state-of-the-art laboratory, are continually developing and expanding the roster of PAXCON® force-resistant protective coatings, which currently includesPX-2100 for anti-spalling protection and PX-3350 for blast mitigation protection. PAXCON protective coatings have been recognized by the U.S. military and the defense industry for their high levels of protection, and have been approved to safeguard government, military and private buildings and vehicles around the globe, including the U.S. Pentagon.

Spall Protection

During a ballistic attack, most severe injuries occur and a significant amount of lives lost are due to ballistic fragmentation or spalling. PX-2100 solves this problem by encapsulating the fragments, which will remain trapped in the LINE-X® material, posing no secondary damage. PX-2100 can be sprayed over any surface hard enough to cause a projectile to spall, such as aluminum, ceramic or steel.

In 2007, PAXCON® PX-2100 was certified by H.P. White Laboratory, Inc., one of the oldest and most respected ballistic and research centers in the nation. Moreover, PX-2100 was also selected for anti-spalling protection by MRAP (Mine Resistant Ambush Protected) vehicle manufacturers, the Pentagon’s top military personnel protection initiative.

Blast Mitigation

PAXCON® offers a revolutionary development in blast mitigation with PX-3350. Known in military and research circles as an Energy Resistant Coating (ERC), the PAXCON coating is flexible, yet stronger than steel. This means that walls outfitted with the unique PX-3350 coating can withstand explosions up to 20 times greater that a normal, uncoated wall. In the event of an explosion, the PAXCON coated walls flex, but stay together. PX-3350 can be applied to numerous types of structural materials, including wood, steel, plasterboard, concrete, brick, block and more.

To demonstrate this, explosive experts and researchers at New Mexico Institute’s Energetic Materials Research and Testing Center (EMRTC) conducted a series of explosions to confirm the protective capabilities of PAXCON PX-3350.

Two identical concrete structures were built, one left uncoated and one coated with PAXCON PX-3350. Both structures contained an office setting complete with dummy, desk and computer equipment. Then a bomb the equivalent of 200 lbs. of TNT and 5 pounds of C4 was detonated 30 feet from the structure.

“The dummy in the PAXCON protected room was unscathed,” said Alan Perryman, EMRTC’s Research Engineer and Test Specialist. “A little dust kicked up, and the walls flexed and pounded like drums, but everything held up just fine. We at EMRTC are very impressed with the way the PAXCON protected room held up.”

To maximize loss of life, terrorists design bombs to use the building itself as a weapon. Flying building fragments act as shrapnel in these types of blasts. Eighty percent of the injuries and casualties that result from an explosion are caused by this fragmentation.

Since the Khobar Towers bombing in Dhahran, Saudi Arabia in June of 1996, the U.S. Government has been testing elastomeric polymers like PAXCON for blast mitigation. PAXCON was founded to be the only coating, out of 27 tested, to pass all of their bomb blast tests (Air Force Laboratory Force Protection Branch).

PAXCON PX-3350 has been applied and is protecting several buildings around the world, including the U.S. Pentagon, the Federal Court House in NY, the Washington Naval Base and several buildings throughout London.

Case Studies

The increased emphasis on homeland security and anti-terrorism initiatives in the wake of the September 11, 2001 attacks paved the way for the U. S. military and defense industry to recognize LINE-X ‘s PAXCON® Protective Coatings for their extraordinarily high levels of protection.

In 2001, the Air Force Research Laboratory released technical specs for using a PAXCON proprietary product for blast mitigation. The PAXCON coating was statistically shown to outperform 27 other competitors in a battery of simulated tests conducted by federal agencies and the U.S. Department of Defense (DOD).

The following year the DOD officially named PAXCON as a vendor/supplier in the bomb blast protective coating category, and a tactical partner in the military’s renovation project of the U.S. Pentagon after the 9/11 attacks. PAXCON completed the first phase of its blast-resistant protective coating application at the U.S. Pentagon later that year, and is currently midway through an extended contract at the landmark defense complex.

Most of the information on the PAXCON applications is classified.

In the fall of 1999, Air Force Research Laboratory (AFRL) began evaluating the LINE-X®PAXCON® elastomeric polymer with concrete block walls. The LINE-X protective coating material is a proprietary elastomeric polymer that is flexible, ductile and has modest strength. It can be sprayed using standard Occupational Safety and Health Administration (OSHA) safety practices for a hazardous material. The thickness of application is relatively easy to control, and the polymer bonds to a wide variety of surfaces.

We coated an 8-foot by 8-foot wall inside and out with the LINE-X polymer, and successfully tested it against 80+ psi blast pressures. Unreinforced concrete block infill walls typically shatter and fail at 2-4 psi pressures. Although the wall experienced large deflections and the concrete block inside the LINE-X polymer coating was severely fractured, the wall remained in place and no fragments entered the cubicle (as seen in the Post-Test image above). The LINE-X PAXCON polymer coating effectively contained the shattered wall fragments and would have prevented serious injury to persons inside the building.

Structure Retrofit

The success of the LINE-X® PAXCON® retrofit was so significant that the Air Force Research Laboratory decided to tackle an even tougher problem - improving the blast resistance of lightweight modular structures. We applied the LINE-X polymer to both the outside and inside of a 10-foot by 20-foot construction trailer. 500 pounds of ammonium nitrate-fuel oil (ANFO) explosive were used to generate 12 psi pressures on the trailer. As can be seen above, the trailer walls underwent large deflections and the LINE-X polymer protective coating had some tears in the membrane, but virtually no wall fragments entered the occupied space.

Structure Program

Based on the successful proof-of-concept testing done on the LINE-X PAXCON, the Air Force Civil Engineer urged AFRL-Tyndall to aggressively pursue a LINE-X polymer retrofit program with a goal of issuing field guidance on retrofitting lightweight structures by summer 2000. These types of structures, characterized by timber stud walls, exterior aluminum siding and interior veneer-plywood paneling, are widely used during extended deployments, such as our forward installations in Southwest Asia.

The results from these tests below further demonstrate the revolutionary protection and durability that is PAXCON Protective Coatings.

U.S. Air Force Approves LINE-X For Bomb Blast Mitigation

At the F.P.E.D. (Force Protection Equipment Demonstration) show on May 9-11, 2001 at the Quantico Marine Base in Virginia, LINE-X® PAXCON® was featured at the Air Force Research Laboratory booth and was demonstrated daily. Air Force representatives told LINE-X that we can tell "the world" that LINE-X PAXCON was the only coating, out of 27 selected, to pass all of their bomb blast tests.

At the demo site, two walls 9' x 9' were erected as the “typical construction that one would find on mobile military buildings . . . used extensively in Southwest Asia by the U.S. Military." These were constructed using 2x4 studs, 16" on center, corrugated aluminum siding and particle board paneling. As you can see from the photos, one of the two walls (the tan colored) was coated with PAXCON. In this test, 50 pounds of TNT was used at a distance of 35 feet. The uncoated wall (white) was destroyed while the PAXCON covered wall was unharmed. As you can see from the bottom right photo, the TNT left a substantial crater.

The PAXCON wall in the photos was actually used twice in testing – this was the second impact. The destroyed uncoated wall was removed and a new-uncoated one was installed for the test shown.

The Air Force Research lab, during a previous test, found that it took the equivalent of at least 1,000 of TNT to "make PAXCON fail and even then it only tore the coating . . . fragmentation was still averted. PAXCON could save lives if applied to buildings subjected to bomb force."

According to the Air Force Research Lab, an 1/8th inch coating, front and back, reduces the "stand off distance by over 50%." And PAXCON should be used for any buildings, structures or vehicles that might get exposed to bomb impact.

H.P. White Certification

In September 2007, PAXCON® PX-2100 was certified by H.P. White Laboratory, Inc., one of the oldest and most respected ballistic and research centers in the nation, for its ability to protect against spalling and fragmentation during a ballistic attack.

All testing was conducted on an indoor range at ambient conditions using calibers 7.62x39mm, 123 grain, lead core ball, 5.56x45mm, 55 grain, M193, ball, and 7.62x51mm, 149 grain, M80, ball ammunition. The test samples were rigidly mounted 60 feet from the muzzle of the test barrels to produce zero-degree obliquity impacts. Redundant pairs of lumiline screens were located at 10 feet and 20 feet. Together with electronic chronographs, they provided bullet velocities at 15 feet.
