V-Wrap 770[1] [G] 36" - 312" CLD 23 EPOXY
V-Wrap PF[2] [G] 60" - 312" CLD 23 EPOXY

[1] Product is applied in 5 layers:
    
    Combine the contents of V-Wrap 770-A pail and V-Wrap 770-B pail together and mix for 3
    minutes using a mixer speed of 400-600 RPM until uniformly blended.  Transfer the mixed
    epoxy into the other pail and mix for an additional 2 minutes.
    
    Layer 1: 10 wet mils of V-Wrap 770 resin.  Mix ratio of V-Wrap 770 resin part A:B is
    100:33 by weight. 
    
    Layer 2: 40 wet mils of thickened V-Wrap 770 resin.  Thickened V-Wrap 770 is achieved by
    adding fumed silica to the resin at a maximum ratio of 1.5 parts fumed silica to 1 part
    resin by volume.
    
    Layer 3: 8 coats of V-Wrap EG50 or V-Wrap EG50B Fabric saturated with V-Wrap 770 resin.
    The thickness of each coat/layer of fabric is 50 mils. No cure time required. Mix ratio
    of V-Wrap 770 resin part A:B is 100:33 by weight.   High strength steel wire (conforming
    to ASTM A881 specification) may be embedded in between fabric layers with V-Wrap 770
    Thickened epoxy. Wires measure 0.2-inch (5 mm) diameter and are helically wound into
    place with a typical spacing of 0.4 inch (10 mm) on center.
    
    Layer 4: 8 coats of V-Wrap C100, V-Wrap C200H, or V-Wrap C400H Fabric saturated with
    V-Wrap 770 resin. The thickness of each coat/layer of fabric is 50 mils.  The thickness
    of each coat/layer of fabric is 90 mils. High strength steel wire (conforming to ASTM
    A881 specification) may be embedded in between fabric layers with V-Wrap 770 Thickened
    epoxy. Wires measure 0.2-inch (5 mm) diameter and are helically wound into place with a
    typical spacing of 0.4 inch (10 mm) on center.
    
    Layer 5: 40 wet mils of thickened V-Wrap 770 resin.  Thickened V-Wrap 770 is achieved by
    adding fumed silica to the resin at a maximum ratio of 1.5 parts fumed silica to 1 part
    resin by volume.
    
    The final cure time and temperature is 24 hours at 75ºF.  There is no cure time required
    between the application of layers.
    
[2] Product is applied in 4 layers: 
    
    Combine the contents of V-Wrap 770-A pail and V-Wrap 770-B pail together and mix for 3
    minutes using a mixer speed of 400-600 RPM until uniformly blended.  Transfer the mixed
    epoxy into the other pail and mix for an additional 2 minutes.
    
    Layer 1: 10 wet mils of V-Wrap 770 Resin.  Mix ratio of V-Wrap 770 Resin Part A:B is
    100:33 by weight. 
    
    Layer 2: 40 wet mils of V-Wrap PF Putty.  Mix ratio of V-Wrap Putty is Part A:B is
    100:31.5 by weight. 
    
    Layer 3: 4 coats of V-Wrap EG50 or V-Wrap EG50B Fabric saturated with V-Wrap 770 resin. 
    The thickness of each coat/layer of fabric is 50 mils.  High strength steel wire
    (conforming to ASTM A881 specification) may be embedded in between fabric layers with
    V-Wrap 770 Thickened epoxy.  Wires measure 0.2-inch (5 mm) diameter and are helically
    wound into place with a typical spacing of 0.4 inch (10 mm) on center. 
    
    Layer 4: : 6 coats of V-Wrap C100HM, V-Wrap C200HM, V-Wrap C220Bm or V-Wrap C400HM
    Fabric saturated with V-Wrap 770 resin.  The thickness of each coat/layer of fabric is
    90 mils. High strength steel wire (conforming to ASTM A881 specification) may be
    embedded in between fabric layers with V-Wrap 770 Thickened epoxy.  Wires measure
    0.2-inch (5 mm) diameter and are helically wound into place with a typical spacing of
    0.4 inch (10 mm) on center.
    
    The final cure time and temperature for the system is 24 hours at 75°F.  There is no
    cure time and temperature between the application of layers.
