PittChar XP - Erector

1 1 of 10 PittChar XP pitt -Char XP Coating offers enhanced performance that's far superior to conventional, rigid epoxy intumescent coatings. Withstands normal movement of steel support structures Damage from contact during construction or normal operating conditions is minimized Good substrate adhesion because of excellent surface wetting characteristics Controlled cure rate prevents inter-coat adhesion problems Can be applied under a wide range of weather conditions, without compromising long-term performance A thick-film intumescent, pitt -Char XP coating offers outstanding fire protective properties. Exposed to fire, its unique chemical composition transforms its surface into a ceramic-like, insulating char that provides thermal protection for the substrate even under hydrocarbon and jetfire conditions.

2 pitt -Char is an epoxy . Its tough, durable coating provides a dense shield to the elements. As a result, pitt -Char can stand up to solvents, acids, alkalis, salts and abrasion. That makes pitt -Char your best choice for harsh weather or chemical environments and virtually any aggressive industrial arctic to tropical climates. pitt -Char coatings have successfully protected substrates in refineries, chemical plants, offshore platforms and a variety of other "high-risk" industrial facilities. Technology pitt -Char XP Coating is unique due to its flexibility. It is the only flexible intumescent epoxy on the market today. pitt -Char XP Coating is the result of the continuing intensive research and development effort in which PPG has invested since l980. pitt -Char XP Coating is the only flexible intumescent epoxy (elongation over 19%) on the market today. The technology has several patents issued with more pending.

3 2 of 10 Intumescence pitt -Char XP Coating is an Intumescent coating. When exposed to fire it swells to several times its original thickness. pitt -Char XP Coating is an intumescent coating. In harsh weather or chemical environments, the tough, durable epoxy coating provides a dense shield to the elements. However, when exposed to a fire, the coating softens, gases are released, and become trapped in the polymer matrix. The material swells or intumesces to several times its original thickness. The resultant foamed char provides an insulating barrier against the heat of the fire. Color Gray (after mixing). May be topcoated. A suitable topcoat recommendation is available from your pitt -Char XP Coating Technical Sales Representative.

4 Percent Solids by Weight 100% In Service Temperature Restrictions For applications on surfaces that exceed 150 F (65 C), consult your pitt -Char XP Coating Technical Sales Representative. Application Method pitt -Char XP coating must be applied only by trained applicators to ensure that proven application practices will be utilized. Air spray or specialized plural component airless equipment approved by PPG is recommended. Troweling can be used for small areas or touch-up work. Drying Time Approximately 24 hours to achieve a Shore D hardness of 25. Shelf Life Minimum shelf life under proper storage condition is: 97-194 and 97-194M - 1 Year from date of manufacture 97-195 and 97-195M - 2 Years from date of manufacture Pot Life At 77 F (25 C) and 50% relative humidity: Approximately 40 minutes. (Pot life is not a factor when using specialized plural component airless spray equipment.)

Value BTU F ft. sqr hr. ( W/m C) pitt Char XP Flexibility This unique resin provides many positive attributes that enhance the coating's performance over other conventional epoxy intumescent coatings. pitt -Char XP is based on a patented, flexible cross-linked epoxy resin. 1. The flexibility allows the coating to relieve internal stresses generated during thermal cycling which prevents cracking and disbonding. 2. The coating can withstand the normal movement and/or vibrations found in steel support structures.

7 3. The high impact strength minimizes damage from physical contact occurring during construction or during normal operating conditions. 4. Pre-fabricated structures can be coated and transported to site without cracking or disbonding of the coating. 5. The resin system has excellent surface wetting characteristics to ensure good adhesion to the substrate. 6. The controlled cure rate allows ample time to install mesh and prevent inter-coat adhesion problems. 7. The flexible coating imparts less stress upon the primer during curing thus minimizing the potential for primer adhesion failure. 8. pitt -Char XP A & B Components can withstand storage at elevated temperatures (pre-heating prior to application) at 60 C for 4 to 5 days without hardening. Problems of hardening in the spray equipment holding tanks and the feed lines has been eliminated unlike rigid epoxy intumescent coatings.

8 9. The pot life after mixing is extended thus minimizing curing of the material in the feed hose, mixer, and spray gun. 10. pitt -Char XP Coating is very user friendly. It allows application under a wide range of weather and temperature conditions, without compromising the long term performance 4 of 10 pitt -Char XP Fire Test Results pitt -Char XP provides up to 2 hours protection against jet fire impingement. pitt -Char Coatings have been fire tested at more than 12 fire testing facilities around the world. Our products have received approvals and certificates from Underwriters' Laboratories Inc. (USA and Canada), Det Norske Veritas (Norway), Lloyd's Registry of Shipping (UK), GASAFE (France), and from several customers based on their own in-house fire testing.
