Cure Titanium Putty hardens in around 4 hours at 21ºC at 12.5mm thick. The functional cure time may be reduced by curing at an elevated temperature, for example, 3 hours at 65 ºC.
Heating can be done with a hot box, heat lamps or other heat sources. Never expose this system to a direct flame.
Proper surface preparation is essential to a successful application. The following procedures should be considered:
- All surfaces must be dry, clean and rough.
- If surface is oily or greasy use Devcon Fast Cleaner 2000 Spray/Cleaner Blend 300 to degrease the surface.
- Remove all paint, rust and grime from the surface by abrasive blasting or other mechanical techniques.
Aluminum repairs: Oxidation of aluminum surfaces will reduce the adhesion of an epoxy to a surface. This film must be removed before repairing the surface, by mechanical means such as grit-blasting or chemical means.
Provide a “profile” on the metal surface by roughening the surface. This should be done ideally by grit blasting (8-40 mesh grit), grinding with a coarse wheel or an abrasive disc pad. An abrasive disc may be used provided white metal is revealed. Do not ‘feather edge’epoxy materials. Epoxy material must be ‘locked in’ by defined edges and a good 3 – 5 mil profile.
Metal that has been handling sea water or other salt solutions should be grit blasted and high pressure water blasted and left overnight to allow any salts in the metal to ‘sweat’ to the surface. Repeat blasting may be required to ‘sweat out’ all the soluble salts. A test for chloride contamination should be performed prior to any epoxy application. The maximum soluble salts left on the substrate should be no more than 40 p.p.m. (parts per million).
Chemical cleaning with Devcon Fast Cleaner 2000 Spray/Cleaner Blend 300 should follow all abrasive preparation. This will help to remove all traces of sandblasting, grit, oil, grease, dust or other foreign substances.
Under cold working conditions, heating the repair area to 38ºC – 43º C immediately before applying any of Devcon’s metal-filled epoxies is recommended. This procedure dries off any moisture, contamination or solvents and assists the epoxy in achieving maximum adhesionto the substrate.
Always try to make the repair as soon as possible after cleaning the substrate, to avoid oxidation or flash rusting. If this is not practical, a general application of FL-10 Primer will keep metal surfaces from flash rusting.
Note: Large surface areas or equipment subjected to thermal shock, impact or constant vibration should have expanded metal tack welded to the surface. The expanded metal should be solvent wiped, grit blasted and solvent wiped again to remove oil, grease anddust. The expanded metal should be raised at least 1.6mm off the surface to ensure that Titanium Putty will get in between and under the expanded metal. Mixing Titanium Putty is formulated to be a dense mix that can be applied easily to overhead and vertical surfaces without running or sagging. Add the hardener to resin and mix thoroughly on a mixing board using a spatula. Do not mix in the containers.
Application For best results, product should be kept and applied at room temperature. Titanium Putty can be applied when temperatures are between 15ºC and 32ºC. When temperatures are below 25ºC, cure and pot life will be longer and above room temperature, cure and pot life will be shorter.
Using a putty knife, trowel or spatula, a very light coat should be applied to “wet out” the surface, allowing for 100% contact and further thickness buildup. Then continue to build up a desired thickness. Titanium Putty can be troweled to a smooth finish with water or by warming the trowel with a torch and lightly toweling over the uncured wear system.Technical Data Sheet Revision
