Directions for use

Surface Preparation
  • Metal – Thoroughly clean the area that is to be repaired, rebuilt or lined, by using Devcon®
    Surface Cleaner. All oil, grease and dirt must be removed before applying Flexane material. All surfaces must be roughened by grinding with a coarse wheel or an abrasive disc pad.
  • Rubber – Thoroughly clean the rubber area with an abrasive pad and Devcon® Surface Cleaner. A grinding wheel may be used to roughen the rubber surface. The rubber surface must be coarse and free from oil and dirt clogged in the “pores”. Using Devcon® Surface Cleaner wipe or roughen surface until the colour of the rubber substrate no longer appears on cloth. The rubber should look new or a deeper black in colour.
  • Priming surfaces – For metal surfaces apply a coat of Devcon® FL10 Primer and allow to dry tack free for 30 minutes. For surfaces that require the maximum tear resistance and are being used in a submersible application or wet environment, use Devcon® FL10 Primer followed by Devcon® FL20 Primer. For rubber surfaces apply a coat of Devcon® FL20 Primer and allow to dry tack free for 15-20 minutes. Use this primer on all types of rubber and urethane surfaces. For porous rubber surfaces, it may be necessary to do multiple coats.
  • Maximum adhesion – Sandblast the surface using an angular abrasive to achieve minimum depth profile of 50 - 75 microns. Abrasive blast clean in accordance with Australian Standard AS1627:4-2005 to a Class 2 ½ near white metal finish. After sandblasting, application surface should be primed immediately to prevent oxidation.
  • Ideal application temperature is 18ºC - 29ºC.
  • Mix Ratio – Resin to Hardener: Weight 72 : 28
------ It is strongly recommended that full units be mixed, as ratios are pre-measured. -------

  1. Add hardener to resin.
  2. Mix thoroughly with a spatula or similar tool (continuously scrape material away from sides and bottom of
    container) for two (2) minutes. NOTE: Flexane putties will thicken rapidly during these first two minutes of
    mixing, but this DOES NOT mean that the polymer is curing.
  3. Transfer the mixed material to the plastic container (included in kit).
  4. Wipe spatula clean, and stir again for two (2) more minutes.
  5. Continue to mix until a uniform, streak-free consistency is obtained

INTERMEDIATE SIZES (4.5kg Units): Use an electric drill and propeller-type Jiffy Mixer to mix the Flexane material until colour is uniform and consistent (approximately 4 - 6 minutes). Make sure the mixer attachment is completely submerged and operating at a low speed during the process. If not, you will be mixing in large amounts of air and this will cause bubbles in the finished product.

  1. Trowel the Flexane Putty into the repair area. Use a spatula to compress the urethane onto the surface. This helps”wet out” the surface and stop any blow holes or air pockets forming which could interfere with adhesion.
  2. Allow to cure six (6) hours before returning equipment to light service. The repair may be ground flush using a 24 or 36 grit sanding disc. Be careful to keep the grinder moving and do not overheat the work surface. Full cure takes 7 days @ 24°C.

Additional Information

Devcon® Flexane Accelerator is used for speeding up the cure of Flexane at temperatures as low as 0°C. Two grams (½ teaspoon) of Accelerator will reduce the cure time of 450gm of Flexane by 50%. Do not use more than 8gm (2 teaspoons) of Accelerator with each 450gm of Flexane.
Storage and Shelf Life

Store in dry conditions between 10°C and 40°C, away from sources of heat and naked flames. Protect from frost.
When stored in original sealed containers, the minimum shelf life is two (2) years.
