Tyfo S Part A:B is 100:34.5 by weight.
Layer 2: 40 wet mils of Tyfo TC, Tyfo S or thickened Tyfo S. No cure time required.
Mix ratio of Tyfo TC Part A:B is 100:23.4 by weight. Mix ratio of Tyfo S Part A:B is
100:34.5 by weight. Thickened Tyfo S is mixed as (Mixed Tyfo S Epoxy) : (Filler
Material) 100:7 Parts by weight. Filler Material may be a combination of fumed silica or
polyethylene fibers.
Layer 3: 8 coats of the reinforcement Layer saturated with Tyfo S. This layer must cure
for 3 hours at 75F. Mix ratio of Part A:B is 100:34.5 by weight. Reinforcement layer
may be a combination of Tyfo SCH-41, Tyfo SCH-41 2X, Tyfo SEH-51A, Tyfo BCC (carbon)
SEH-81A (glass), Tyfo WEB (glass),Tyfo BC (glass), Tyfo SEH-31A (glass), Tyfo SEH-31A
(glass), Tyfo SCH-41S (carbon) and Tyfo SCH-41S-2X (carbon).
Layer 4: 20 wet mils of Thickened Tyfo S. Final cure is 48 hours at 80°F. Minimum Shore
D hardness of 80. Mix ratio of Tyfo S Part A:B is 100:34.5 by weight, then (Mixed Epoxy)
: (Filler Material) 100:7 Parts by weight. If 80 hardness is not achieved, continue
curing in 3 hour intervals. Hardness shall be based on average of 5 measurements.
Filler material may be a combination of fumed silica or polyethylene fibers.
Alternate Part 4: 2 coats (13 we mils each) of Tyfo PWC. First coat must cure for 24
hours at 75°F prior to the application of the second coat. Final cure is 24 hours at
