VF 774
Why Forton VF 774?
• Consistent color over time – no yellowing/fading• Demonstrated long term ductility• The only latex that has withstood the test of time30+
Years
• 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
Quality GFRC
• Improved workability of the mix• Spray on vertical w/o sag• Improved pumping
• No foaming• Excellent pigment dispersion
Improved Processing
• VF 774 is designed for GFRC• Monomer mix, particle size, solids
content, additive package• Excellent batch to batch consistency

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
Long Term Durability
w/o Forton -- brittle break, straight break line, few fibersw/ Forton -- ductile break, jagged break line, abundant fibers

: THE time tested material for GFRC
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
