- Designed for bonding and coating projects that require extended working time
- Ideal for use in warmer conditions when fast-cure systems set too quickly
- Cures to a high-strength, moisture-resistant solid when mixed with 105 Resin
- Provides excellent bonding and barrier coating properties for marine applications
- Not intended for clear coating—use 207 Hardener for bright finishes
- Mix ratio: 5 parts 105 Resin to 1 part 206 Hardener (by volume)
- Pot life of 20 to 25 minutes at 72°F (22°C) for longer application time
- Hardener Cure Temperature range is 60°F to 100°F
- Cures to a solid state in 10 to 15 hours; full working strength in 1 to 4 days
- Minimum recommended application temperature: 60°F (16°C)

Product Details
Storage & Shelf Life
Store at room temperature. Keep containers closed to prevent contamination.
With proper storage, resin and hardeners should remain usable for many years. After a long storage period, verify the metering accuracy of the pumps. Mix a small test batch to assure proper curing. Over time, 105 Resin will thicken slightly and will therefore require extra care when mixing. Repeated freeze/thaw cycles during storage may cause crystallization of 105 Resin. Warm resin to 125°F and stir to dissolve crystals.
Hardeners may darken with age, but physical properties are not affected by color. If clear finishing, be aware of a possible color shift if very old and new hardeners are used on the same project.
