Cure A 12.7mm thick section of Devcon Plastic Steel Putty will harden at 21ºC in 4 hours. The material will be fully cured in 16 hours at which time the material can be machined, drilled or painted. The actual cure time of epoxy is determined by the mass used and the room temperature at time of repair.
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.
Aluminium repairs: Oxidation of aluminium 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), or by grinding with a coarse wheel or 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 adhesion to 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.
Mixing Plastic Steel Putty (A) is formulated to be a dense mix that can be applied easily to overhead and vertical surfaces without running or sagging. For the 500g and 1Kg kits, empty the Resin and hardener onto a mixing board and mix using a spatula. Do not mix in the containers. For the 10Kg kit, add the hardener to the resin and mix using a T shaped mixer or Jiffy ES mixer attached to a power drill. Fold the material by vigorously moving the mixer up and down until a uniform mix has been achieved. Once mixed, immediately spread out the mass of material onto a suitable area before use to avoid a rapid exotherm and associated reduction in potlife.
Application For best results, product should be kept and applied at room temperature. Plastic Steel Putty(A) can be applied when temperatures are between 13ºC and 52ºC. Spread the putty over prepared surface with a putty knife. Press firmly to ensure maximum surface contact and avoid trapping air. To bridge large gaps or holes use fibreglass, sheet metal or wire mesh.
