1 Makrolon and Hygard Advantage for security products

2 Makrolon and Hygard protects against forced entry attempts or attacks to aesthetics or integrity Covestro has built a reputation for quality polycarbonate materials With a complete line of containment, forced entry, and ballistic rated polycarbonate products, Covestro is committed to supplying high quality security glazing materials to commercial, public, private, and government buildings. Based on the virtually unbreakable Makrolon polycarbonate sheet, the products maintain an aesthetically pleasing, glass-like appearance while providing forced entry and ballistics resistance. Performance has been tested by accredited laboratories and the results show the materials are an effective first level of defense against attack or unlawful entry and gives time for law enforcement officials to gain control. The Makrolon and Hygard ** Advantage Safety-hardened entrance for schools Virtually unbreakable Exceptionally durable Optically clear Forced entry protection Ballistic rating Reduced Weight: Approximately 50% lighter than glass laminate of the same thickness. No spall providing an extra level of protection. Won t spider web or white-out clear line of site under attack. Makrolon and Hygard products feature a hard coat that resists abrasion, chemical, and graffiti attack. Makrolon 15 sheet has a 15-year limited product warranty. See website for details Hygard products offer a 7-year limited product warranty.

3 Hygard The ultimate security product with AR hard-coat technology provides exceptional resistance for abrasion and UV degradation Covestro is a recognized market leader in the production of high performance thermoplastic sheet for over half a century. As a global leader of high performance polycarbonate glazing products, Covestro has been at the forefront of security glazing innovation. Covestro s laminated sheet products, featuring Makrolon AR hard-coat technology, assures long lasting surface clarity and resistance to yellowing. Whatever the security application, Hygard laminates offer unsurpassed performance versus competitive glass and glass clad polycarbonate products. With its unique multilayer construction, Hygard can protect against both physical attack and gunfire from high powered hand guns. This laminate line offers multiple levels of protection ranging from certified containment glazing to Level 6 bullet-resistant material. Hygard laminates will not spider web or spall. This allows for clear line of sight, which can be critical for appropriate response in the event of an attack. Designed for security installations such as detention and correctional centers, government facilities, and banks, Hygard is being used increasingly for protection in schools, gas stations, convenience stores and other cash transaction areas.

5 Hygard laminates Fabrication Hygard laminates a portfolio of security rated polycarbonate and polycarbonate/acrylic systems that easily fabricate using standard cutting tools. Recommended are carbide-tipped cutters they last longer and cut a cleaner edge. Leave the masking on the product while fabricating to protect against surface damage. Remove masking soon after installation prolonged outdoor exposure degrades the film making it difficult if not impossible to peel off. Proper fabricating practices are especially important to follow when cutting parts intended for security applications to insure product integrity with respect to strength properties and performance ratings. Sharp cutting tools are important, as is feed rate control, do not force cutting appliance to avoid material overheating. Circular Saw Circular saw blade carbide tipped, triple chip tooth design, cuts clean and last longer than high strength steel. Blade is hollow-ground, and slotted for expansion and cooling. Blade cutting speed ft/min.

Increase blade tooth size 2. Reduce saw speed 3. Increase feed rate 4. Use air to cool blade 5. Use blade lubricant compatible with Makrolon Polycarbonate Sheet 6. Inspect blade for sharpness 7. Check blade-fence alignment 8. Reduce number of sheets in stack PROBLEM: Chipping SUGGESTED SOLUTIONS: 1. Decrease blade tooth size 2. Increase saw size 3. Provide better clamping and/or support for sheet stack 4. Reduce feed rate 5. Check blade and arbor for wobble 6. Inspect blade for sharpness 5

6 Hygard laminates Fabrication continued Milling/Routing Two or three fluted carbide-tipped router bits cut clean edges on Hygard laminates. Feed sheet against the router bit rotation and use a fence for sizing when making straight cuts. Router speeds 20,000 25,000 rpm, use straight 2-3 fluted carbide-tipped or high-speed bits. Feed product at a controlled rate to avoid overheating, minimizing vibration producing a smooth part edge. Drilling Standard drills and bits fabricate Hygard laminates, however specially designed drills and bits perform much better. Drills for plastics generally have wide, polished flutes to reduce friction, as well as spiral or helix designs to remove chips quickly. *Use drill-point angles larger than 90 degrees General guidelines for drilling Hygard laminates: Use carbide-tipped drills, they resist gumming and maintain edge sharpness longer than standard drills Avoid cutting fluids most are not compatible with polycarbonate Cool work if necessary by forced-air stream Summary on cutting: Use only sharp cutters Holes drilled slightly oversized Holes drilled off sheet edge by distance at least one-times diameter of hole Drill counter-bore hole, do not countersink Forced air stream only as cooling medium, use no cutting fluids Material overheating causes- speed/feed rates, dull cutter, cutter design Cut edges must be smooth, sand coarse surfaces and chatter marks Leave masking on product during fabrication, remove soon after installation Use cleaners compatible with polycarbonate, confirm with manufacturer if unsure Drill bit design includes cutting-lip angle Hole Diameter Drill Speed (RPM) 1/ / / Negative Rake Clearance Angle Use sharp drills for cleanest cut and frequently clear the hole of chips. Avoid overheating otherwise stress build-up in the material may have an adverse effect on mechanical properties compromising product performance and reliability. If drilling holes, drill them off the part edge by 1-2-times the diameter. Avoid holes in parts intended for ballistic rated applications. 6

7 Hygard laminates Installation Frame Design Frame design requires careful consideration for glazing intended to provide security rated protection. Be mindful in selecting a metal frame that matches the same protection level as the specified Hygard laminate. Corner design Mitered corners require added bracing usually attaching angle sections at these locations are enough in strengthening the overall frame. A continuous metal extrusion is a better frame design. Metal Angle Bracing Product performance relies a great deal on method of attachment, with importance on the assembly and thermal expansion taken into account. Rabbet Depth Contraction Expansion Edge Engagement Hygard laminate NO YES Glazing Recommendations Frame system must have rating equal to the Hygard laminate specified Hygard laminate dimension must have allowance for at least 1 inch edge engagement and frame has adequate rabbet for sheet thermal expansion movement (0.060 inch per 12 inches linear dimension) Use only gaskets, tapes and sealants compatible with polycarbonate Setting block use strips of polycarbonate or Santoprene rubber Remove protective masking soon after completing the installation, prolonged exposure to the outdoors will degrade the film making it difficult if not impossible to remove Santoprene is a trademark of Exxon Mobil Corporation 7
