VFI®-2839 95 A Aliphatic Casting Rubber

VFI®-2839 95 A Aliphatic Casting Rubber is a fast setting, 95 A hardness, two-part spray or injected polyurea with excellent physical properties. An aliphatic polyurea provides color stability and moisture insensitivity to give a very versatile product for indoor and outdoor products. With good chemical and solvent resistance, VFI-2839 is able to withstand harsh environments and climate changes. A low viscosity allows for multiple processing methods for many different final applications.

95 A fast setting two-part polyurea rubber part that has good elongation, tensile strength, and UV stability.

Product Details

  • Product Color: Standard color is black. Additional colors and color matching services are available contact Volatile Free, Inc.
  • UV Stability: This product is UV color stable. 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. Before coating surfaces adhesion testing should be done and/or a primer before coating. Contact Volatile Free Inc. with any additional questions.
  • Mixing: Pre-mixing Poly (B) components until uniform is required before injecting or spraying. 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 40°F and 100°F when the product is being used. The speed will increase with temperature beyond 72°F. Ensure surfaces are properly prepared before applying or injecting the material. Contact Volatile Free, Inc. for more information on recommended release agents or sealants.
  • Primers: 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.
