BallisticSkin™ Polyurea
Quick Overview
BallisticSkin™ super-polymer technologies are designated into 3 groups: BS-NEAT, BS-LAM and BS-SM. BS-NEAT may be cast optically clear to a thickness of 1.25″ (31mm) to handle intense hand gun fire at close range with fire-power from multiple rounds of 44 magnum, 9 mm and 45 caliber bullets. As shown in shown Fig. 1 a couple of 45 caliber bullets were stopped at a depth of .375″ into BS-NEAT at close range. BS-LAM is specificially designed for composite builds using numerous inner members such as ultra hard steels, ceramics, kevlar fabrics and ultra-dense engineered thermoplastics. BS-SM is an ultra tough energy absorbing skin used primarily in shrapnel mitigation.
BallisticSkin super-polymer materials are capable of absorbing very high impact energy, extremely high tear resistance and can withstand high heat capacities whereby demonstrating ultimate toughness. The spray version of BallisticSkin (BS-SM) is used to strengthen a variety of military grade substrates used for tranportation vehicles, armorment assemblies and structural building reinforcement as shown in Fig. 2 where BS-SM is sprayed on a high strength very hard steel (Brinnel 60-65) panel at a thickness of 3.6 mm. Shown from the back side, the left hand side shows the dark green BS-SM super-polymer coating strenghthening the hard steel keeping it from shattering into shrapnel and panel failure cracking.
Generally, BallisticSkin™ super-polymers are used in some type of ballistic shielding applications. These materials may be applied to many types of structural substrates which include high strength steel, 6061 Aluminum, high-strength composites, wood laminates, reinforced masonry and concrete. These unique materials provide extreme protection for safe-houses, personnel vehicles, government buildings, armed outposts and special aircraft. For specific applications, please contact our technical support group.
Sprayed samples must be aged 30 days at room temperature prior to shooting.
Please call or email our Technical Support Group for any questions regarding material, application or prospective uses.
Technical Application Data
Physical application of spray BallisticSkin BS-SM requires a 2-component high pressure liquid pumping machine. BS-NEAT and BS-LAM may be hand batch mixed for the casting process. Surfaces must be prepped for cleanliness and/or use an adhesion primers to acquire superior adhesion which is vital to contributing to the total energy absorption of the system. Application temperature ranges from 20°F to 150°F. For the hand mix materials, stir for 1 minute vigorously or mix with a hand drill jiffy mixer. Casting working time is 10 min. at 75°F. Full cure occurs within 24-48 hours for all BallisticSkin super-polymer materials. Functional operation temperature ranges from -20°F to 250°F. Surface appearance is normally glossy and smooth for all grades. BS-LAM and BS-SM may be color-tinted if desired. Refer to MSDS for material and safety standard procedures.

Substrate Surface Preparation
Preparation of substrate surface prior to the application is extremely important as durability is only as good as the weakest link in the coating system.
The substrate must be clean, dry and free from grease and dust that might affect adhesion. Steel panels should be shot blasted to a SSPC 4. Remove dust and do a solvent wipe using acetone or MEK . Apply WBE2 epoxy primer at 4-6 mils .Allow the WBE2 to become tack free before spraying BS . Aluminum panels should be acid washed with muriatic acid 85% until the gloss is gone and the aluminum has a white color. Wash with water and dry before spraying BS. Ceramic tiles should be clean and dry after an acetone wipe . WBE2 should be applied at 4-6 mils and allow to dry prior to spraying BS.
