VFI®-145 95 A Polyurethane Casting Rubber

VFI®-145 95 A Polyurethane Casting Rubber is a fast setting, 95 A hardness, high durability rubber with good rebound properties to create a versatile urethane rubber. A high amine content gives good chemical resistance and low temperature flexibility for increased use and durability through multiple cycles. VFI-145’s fast setting capabilities gives a quick demold time and increased part production rate. A low viscosity allows for increased part sizes while maintaining final properties.

95 A fast setting two-part urethane rubber part that has good elongation and tensile strength that allows for varying part sizes.

Product Details

  • Product Color: Standard colors available are neutral and black. 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 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: For specific instructions and equipment requirements, contact Volatile Free, Inc.
  • Surface Preparation: All surfaces should be cleaned, prepped and free of any oils, dirt or debris. To demold, material must be non-porous or sealed with a chemical sealant. A release agent should be used on all products intended to be demolded. 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. Ensure surfaces in contact with the material are properly sealed and released before mixing to prevent any unwanted adhesion. Contact Volatile Free, Inc. for more information on recommended release agents or sealants.
  • Primers: Contact Volatile Free, Inc. on 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.
