- Pouring concrete expansion joints
- Casting flexible parts and moulds
APPLICATION INFORMATION CURE
Allow Devcon Flexane 80 to cure for 6 hours before returning equipment to light service. Once cured, the repair may be ground flush using a 24 or 36 grit open coat-sanding disc. Be careful to keep the grinder moving and do not overheat the work surface. De-mould Flexane Liquids in approximately 5-10 hours. Note: To shorten the cure time of all Flexanes, add Devcon’s Flexane Accelerator (see Flexane Accessories Technical Data Sheet).
SURFACE PREPARATION
METAL SURFACES: Thoroughly clean the area that is to be repaired, rebuilt or lined by using Devcon Fast Cleaner 2000 Spray/Cleaner Blend 300. 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 SURFACES: Thoroughly clean the rubber area with an abrasive pad and Devcon Fast Cleaner 2000 Spray/ Cleaner Blend 300. You may take a grinding wheel and roughen the surface. The rubber surface must be coarse and free from oil and dirt clogged in the ‘pores’ of the rubber. Using Devcon Fast Cleaner 2000 Spray/Cleaner Blend 300, 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.
CONCRETE SURFACES: Concrete being a very porous substrate requires multiple cleaning. Degrease the area with Devcon Fast Cleaner 2000 Spray/Cleaner Blend 300 and rinse the area. A power washer or steam cleaner is useful for quicker and efficient cleaning. Let the floor dry thoroughly before applying the Primer and Flexane.
PRIMING SURFACES
METAL SURFACES: On metal surfaces apply two coats of FL-10 Primer and allow to dry tack-free for 15 minutes.
RUBBER SURFACES: On rubber and urethane surfaces apply a coat of FL-20 Primer and allow to dry tack-free for 15 – 20 minutes. On porous rubber surfaces, it may be necessary to do multiple coats.
CONCRETE SURFACES: Concrete being a “porous” substrate may need multiple coats for proper adhesion. Let Primer dry for 30 minutes between coats.
WOOD & FIBREGLASS: Use FL-20 Primer for all Wood and Fiberglass products. Softwoods will need two coats because of their absorption characteristics.
IMMERSION SUBSTRATES: Use Primers FL-10 and FL-20 to coat any metal substrate that will be immersed in any aqueous solution. First, apply the FL-10 Primer and let it dry for 60 minutes. Next coat with FL-20 Primer. Let it dry for 30 minutes before applying the Flexane material.
MIXING
Add curing agent to the Flexane resin container and stir vigorously for 2 minutes. Ensure that the two parts are fully mixed by scraping along the bottom and side of the container. For quantities larger than 500g use an electric drill and mixer to mix the Flexane material. Make sure the mixer attachment is completely submerged during the mixing process. If not you will be mixing in large amounts of air and this will sometimes cause bubbles in the finished product.
APPLICATION
How do you use Flexane 80 Liquid ? EXPANSION JOINTS
These are areas between concrete slabs that are “stress” points. These areas move with pressure from underneath the concrete surface or from stress being applied from the top of the slab. To fill these cracks a special material like Devcon Flexane 80 Liquid is required to take the expansion and contraction that occurs in these areas.
The crack must be cleaned to remove any loose particles and chips of concrete. Also make sure there is no grease or oil in the joint area, if so follow the degreasing procedure.
Next check the depth of the expansion joint. If the concrete slab is 4” thick, the joint should only be half that amount.
Prime the joint using Devcon’s FL-20 Primer. Apply two coats to the concrete edges.
Take a piece of round foam backer rod and insert it into the joint. If this is not available, use a fine sand grain to fill the bottom of the joint exactly halfway.
Pour mixed Flexane 80 Liquid into the joint. Pour from one side of the joint and let the material fill the entire area. This helps all the air to escape, thus no “air bubbles”. Do not overfill the joint area, as the Flexane material will run into the concrete. Leave a slight depression below your desired height.
LINING APPLICATIONS/NOISE REDUCTION
Devcon Flexane 80 has an outstanding quality of having “elasticity”. This is beneficial for applications requiring impact resistance such as feeder bowls in production plants, chutes in cement, coal or mining plants and cyclones. Lining applications require a good depth of coating along with the proper Primer for good adhesion.
For good adhesion follow the cleaning method for the appropriate surface. A good surface profile is required for excellent adhesion. Abrade the surface of the wear area with an abrasive disc pad and clean thoroughly.
Next, apply a coating of FL-10 Primer. Let it dry thoroughly and follow with a coating of FL-20 Primer. Let dry for 30 minutes before continuing.
Before applying the Flexane material ensure the substrate has a defined “butt joint”. Leaving an edge will create the possibility of the aggregate “undercutting” the material. Apply the Flexane to the substrate. Apply at least 1/16” of the material if possible for better wear resistance to the substrate.
SHELF LIFE & STORAGE
A shelf life of 2 years from date of manufacture can be expected when stored at room temperature (22ºC) in their original containers.
