VFI®-3600BM Polyurethane Base Coat

VFI®-3600BM Polyurethane Base Coat is used as a protective elastomer for impact and strength. A polyurethane base coat provides strength and toughness underneath a UV stable top coat in order to increase the properties as a system. An easy 1 to 1 mix ratio allows for rolling VFI-3600BM and does not require a two component sprayer to apply. VFI-3600BM Polyurethane Base Coat has zero VOC’s and can be used in areas with strong VOC regulations.

Product Details

  • Product Color: Standard color available is gray. For additional premium colors or color matching services contact Volatile Free, Inc.
  • UV Stability: This product is NOT UV color stable and has no long-term UV testing. For additional information contact Volatile Free, Inc.
  • Coverage/Thickness Requirement: Contact Volatile Free, Inc. for more thickness requirements and specifications.
  • Storage Stability/Shelf Life: 12-month shelf life from date of manufacture when stored and sealed in unopened containers between 40°F - 75°F. Opened containers may be resealed with a nitrogen purge, but shelf life will be significantly shortened. Material should be brought to a minimum temperature of 65°F before use.
  • Equipment: 3600BM batch mix two component urethane basecoat may be rolled or brushed, because it has a slower gel time. For specific instructions and equipment requirements, contact Volatile Free, Inc.
  • Surface Preparation: Surface preparation depends on application and substrate being coated. All surfaces should be cleaned, prepped and free of any oils, dirt or films that could affect the product adhesion. Contact Volatile Free Inc. with any additional questions.
  • Mixing: Pre-mixing Poly (B) components until uniform is required before combining Poly (B) and Iso (A). If pouring material by hand pre-weighed Poly (B) must be poured into pre-weighed Iso (A) and then mixed until uniform and transferred to a new container to mix until uniform again before use. Product must be fully mixed and used before the duration of the pot life. Mix times may vary depending on volume and mixing method, please contact Volatile Free, Inc. for more information on any specific mixing questions and requirements.
  • Material Application: Temperature should be between 50°F and 100°F when the product is being used. The pot life will shorten with any increases in temperature beyond 72°F. Standard application is a coat thickness of 32 wet mils and may increase depending on final coverage rate Contact Volatile Free, Inc. for more information on recommended application methods.
  • Primers: Volatile Free, Inc. recommends adhesion patch testing before use and additional adhesion patch testing with the chosen primer. The following are approved primers for use with 3600 two component urethane basecoat. Contact Volatile Free, Inc. with any primer questions.
  • Cleanup: Preferred clean-up solvent is xylene or MEK. Please contact Volatile Free, Inc. for more information on clean-up of equipment and tools.
  • Thinning: Do not thin prior to application.
  • Precautions: Contains isocyanate that may be irritating to the skin and is toxic if inhaled as particulate matter. See Safety Data Sheet for complete safety data. Do not add any foreign material to this product. Avoid prolonged breathing of vapors and prolonged or repeated skin contact. Use only with adequate ventilation.
