WEST SYSTEM Specialty Epoxies

WEST SYSTEM® Six10® Thickened Epoxy Adhesive

Six10 is a two-part thickened epoxy adhesive in a convenient, self-metering cartridge. For permanent, waterproof, structural gap filling and gluing.

Six10 Adhesive is a two-part epoxy gel adhesive that provides strength and reliability with the convenience of a single-part product. The self-metering coaxial cartridge dispenses a gap-filling structural epoxy that bonds tenaciously to wood, metals, fibreglass and concrete. The tube comes with a static mixer that lets you lay down a bead of thickened epoxy with any standard caulking gun.

Six10 features

Convenience of the Six10 self-metering cartridge

WEST SYSTEM® Six10® Thickened Epoxy Adhesive is packaged in a specially designed, self-metering cartridge. This innovative container provides many useful features:

  • It separates the resin and hardener for long-term storage
  • It accurately meters the proper 2:1 resin/hardener ratio
  • It dispenses the amount desired
  • It fits into a standard caulking gun (not to be used with a pneumatic caulking gun)

The cartridge works by utilising the movement of the piston to dispense the resin and hardener from separate chambers simultaneously. The moulded chambers and passageways accurately control the ratio and prevent the resin and hardener from contacting each other until they are outside the cartridge.

The WEST SYSTEM 600 Static Mixer blends the resin and hardener as it passes through the device. One is included with each cartridge.

Handling

Six10 shear-thinning properties

Experienced WEST SYSTEM users are familiar with the handling characteristics of 105 Epoxy Resin®-based epoxy thickened with 406 Colloidal Silica Filler that allows it to be non-sagging, yet trowel easily. Six10 Adhesive provides the same handling properties right out of the cartridge but achieves it with shear thinning, a property that allows the viscosity of the adhesive to become lower when a shear force is applied.

A shear force is applied when the epoxy is mixed or spread out over a surface, which causes the viscosity of the Six10 to become lower, resulting in a “thinner” consistency. When you are done applying or mixing Six10 and it is no longer being worked, or “sheared,” it will start to increase in viscosity and develop a thicker consistency.

This shear-thinning property enables Six10 to be easily dispensed out of the coaxial cartridge and through the static mixer and then tooled smoothly into a fillet that won’t sag during the cure cycle. The shear-thinning property also enables Six10 to be used for wetting out light to moderate weight reinforcing fabrics such as fibreglass and carbon fibre. This feature makes the product convenient for performing small fibreglass boat repairs.

Fabric wet-out: if you use a stiff plastic spreader, Six10 can wet out any fibreglass fabric lighter than approximately 400 g/m² (12 oz/yd²) as a result of its shear-thinning characteristics.

Wetting out reinforcement fabric with Six10

The physical properties of WEST SYSTEM Six10 were developed to ensure good adhesion in many applications. Six10 will create a fibreglass laminate much closer to 105 Resin epoxy laminate properties. Six10 will wet out fabrics up to approximately 400 g/m² (12 oz/yd²). For heavier fabrics, a 105 Resin-based epoxy with its low viscosity should be used to ensure thorough fabric wet-out.

Application

Using Six10

Six10 bonds to wood, fibreglass, metals and masonry. With the 600 Static Mixer (included) you can dispense fully mixed adhesive right where you need it using a standard caulking gun. See the convenient, self-metering cartridge in use.

Trim the mixer tip to suit your job:

Bead length by mixer tip opening
Tip opening (diameter)Bead of adhesive, approx.
6.4 mm (1/4″)4.6 linear metres (15 ft)
3.2 mm (1/8″)22.9 linear metres (75 ft)

Six10 cures to a solid state in 5–6 hours and reaches full cure in 24 hours at 25°C.

Six10 working time

The WEST SYSTEM 600 Static Mixer that comes with the Six10 epoxy cartridge blends the resin and hardener as it passes through the device. Often, you’ll apply some epoxy to your work surface and proceed with assembly. While you’re working, the adhesive in the mixer will eventually begin to cure. You should have about 42 minutes before you need to dispense more epoxy.

Six10 stays workable in the static mixer for 42 minutes, making it practical for long or complicated assemblies. The hardener provides a long open time but has fast through cure.

Fillets with Six10

With the 600 Static Mixer attached to the Six10 cartridge, it’s easy to lay down a bead of thickened epoxy adhesive right where you need it. The consistency of Six10 Adhesive is perfect for fillets.

Caulking gun: Six10 fits into a standard caulking gun. It is not to be used with a pneumatic caulking gun.

Repair guide

Fast osmotic blister repair with Six10

  1. Open the blisters

    Open blisters with a small abrasive tool like 3M’s Roloc™ 50 mm (2″) diameter sanding disc with 60-grit sandpaper. Make sure you have removed the entire blister, including the edges of the blister dome.

  2. Clean the cavity

    Wipe the cavity clean with an alcohol prep pad or paper towels that have been soaked in isopropyl alcohol. Be generous with the alcohol and change towels frequently so the contaminants are removed rather than spread. Repeat the alcohol wipe process and allow the laminate to dry to the touch. It is particularly important to repeat the alcohol wipe on blisters that were fluid-filled at the time they were ground away.

  3. Fill with Six10

    Fill the cavities with Six10 Thickened Epoxy Adhesive dispensed through the static mixing wand.

  4. Spread the Six10

    Spread the Six10 Adhesive flush with the surrounding hull with a wide putty knife or plastic spreader. Avoid overfilling the cavities because Six10 is difficult to sand.

  5. Wet sand

    Wet sand with 80–120-grit wet/dry sandpaper or wash with water (no soap, no ammonia) and sand dull with 100-grit sandpaper. If you are using Six10 in warm conditions, you should be able to wet sand and bottom paint later the same day. If you’re working in cooler temperatures, allow the epoxy to cure overnight before sanding.

  6. Paint

    The final step is applying your choice of bottom paint to complete this fast blister repair job.

This method is recommended for minor, isolated blister repairs. Extensive damage due to osmotic blisters should be repaired following the instructions starting in Section 9 of the WEST SYSTEM Fiberglass Boat Repair and Maintenance Manual.

Storage

Storing Six10 cartridges

  • The nose plug covers the two separate ports that emit resin and hardener and prevents leakage and contamination. Remove the plug before use and replace it afterward. As resin is emitted from one side and hardener from the other, the plug will get a residue of resin and hardener on it. For best results, clean the tip before replacing the plug. Try using a stir stick, paper board or poster board with a slot cut into it. Use this to swipe over the divider.
  • When you replace the plug, be sure it is oriented the way it was when it was first removed, otherwise resin and hardener on the plug will contaminate the opposite side of the port and cure. To prevent this, before you use the product remove the retaining nut and put one marker dot on one side of the removable plug and a corresponding dot on the same side of the cartridge. When replacing the plug, you’ll always be able to orient it properly.
  • Replace the plug, align the dots as described earlier, then replace the threaded cap. The tube will be ready for use next time you need it. Always replace the retaining nut, as hydraulic pressure may force the plug out.
  • Store cartridges of Six10 Thickened Epoxy Adhesive away from sunlight in a cool, dry place, but don’t refrigerate them. On a boat, store the tubes in a plastic zip-lock bag so they stay dry. When properly stored, Six10 will remain usable for years.
