Transcript

  • 1. VF 774
  • 2. Why Forton VF 774? 30+ Years Quality GFRC Improved Processing Quality Latex • Consistent color over time – no yellowing/fading • Demonstrated long term ductility • The only latex that has withstood the test of time • Maximum 28 day strength w/o 7 day wet cure • High density material without voids • Color consistency from batch to batch • Virtually eliminate face cracking • Improved workability of the mix • Spray on vertical w/o sag • Improved pumping • No foaming • Excellent pigment dispersion • VF 774 is designed for GFRC • Monomer mix, particle size, solids content, additive package • Excellent batch to batch consistency
  • 3. Mix behavior Other Acrylics SBRs Water reducing effect ++ -- + Controls foaming ++ -- - No offensive odor + + -- There are clear processing advantages when using Forton over other acrylics, SBRs or no polymer.
  • 4. 28 Day Flexural Ultimate Flexural Ultimate at 5% Glass Fiber 2850 2800 Flexural Ultimate (psi) 2750 2700 2650 2600 2550 2500 2450 2400 2350 Forton Acrylic 1 Acrylic 2 Acrylic 3 SBR 1 SBR 2 No Polymer
  • 5. Long Term Durability • Forton increases the strain to failure at 28 days • Field tests show that high strain to failure is only maintained with Forton
  • 6. Long Term Durability Aged 16 year w/o Forton Aged 16 year w/ Forton w/o Forton -- brittle break, straight break line, few fibers w/ Forton -- ductile break, jagged break line, abundant fibers
  • 7. Face Cracking The use of 6% Forton eliminated face cracks in panels that consistently cracked without. Without Forton With Forton
  • 8. Why Use Forton? Property Other Acrylics SBRs No Polymer  Designed for GFRC    Manufactured to tight specifications  - - Forgiving slurry  - -  Will not foam     No strong offensive odors     Eliminates 7 day wet cure  - -  Will not yellow  -   Prevents face cracking  - -  Highly ductile GFRC         … proven to last for decades : THE time tested material for GFRC
  • 9. Summary • The foundation for quality GFRC – designed specifically for GFRC – manufactured to tight specifications • Consistently produces desired results • Produces GFRC with maximum 28 day strength w/o 7 day wet cure • Produces more water resistant GFRC with lower water absorption compared to SBR latexes • Prevents face cracking • Produces highly ductile GFRC that remains ductile for decades • The time tested material for GFRC
