Forton VF-774

Forton™ VF-774 is an all acrylic, co-polymer dispersion (51% solids) specifically formulated for the GFRC production process. VF-774 is UV stable. It is further formulated to be stable and durable in the high pH Portland cement-based GFRC composite.

The Primary Benefits of Using Forton™ VF-774 are:

• Elimination of the seven day wet cure required to achieve the maximum strengths of the GFRC composite.
• Significant improvements in the long-term durability of the GFRC composite, especially the maintenance of the long-term flexural strain to failure property, i.e. ductility of the composite.
• Improved workability of the mix at low water/cement ratios, further enhancing the strength of the cured cement matrix.
• Easy spraying of vertical surfaces without having the face mix sag.
• Complete dispersion of iron oxide pigments for batch-to-batch colour consistency of face mixes.
• UV stability of the Forton™ polymer means architectural finishes maintain their “as produced” colours.
• Hard cured face mixes for better sand blasting uniformity.
• Tighter, denser cured product, which reduces absolute moisture absorption and vapor permeability while at the same time significantly reducing the rate of absorption as a function of time.
• Elimination of crazing and spider cracking in the face mix due to the soft polymer particles in between the cement particle and the sand grain.

PCI Compliance: Forton™ VF-774 complies with Appendix G of MNL 130, the Manual for Quality Control for Glass Fibre Reinforced Concrete Products from the PCI for the elimination of the seven day wet cure.
