LOCTITE EA 3478 - 453g (high strength epoxy resin with ferro-silicon filler, up to 120 °C)
No.
IDH.2941219
Product description:
LOCTITE EA 3478 is a two-part ferro-silicon filled, 100% solid epoxy resin system. It is ideal for restoring parts worn by mechanical impact and/or corrosion. Typical applications are restoring tolerances to worn shafts, repairing worn keyways, repairing damaged housings, filling pitted surfaces in worn machinery, and restoring fit to bearing housings. Further information about the product: biuro@woronko-kleje.pl
Steps to achieve the best adhesive results:
1. Remove dirt, oil, grease, etc. with a suitable cleaner, e.g. high pressure water cleaning system using LOCTITE SF 7840 (Loctite Natural Blue cleaner/degreaser).
2. Blast all surfaces to be coated with a sharp edged angular grit to a depth of profile of 75 to 100 microns and a degree ofcleanliness of Near White Metal (SIS SA 2½ /SSPC-SP 10).
3. After blasting, metal surfaces should be cleaned with waterless cleaner, e.g. with Loctite SF 7611 (Loctite Pro Strength Parts Cleaner), and be coated before any oxidation or contamination takes place.
4. Metal that has been in contact with salt solutions, e.g. seawater, should be grit blasted, high-pressure water blasted, and left for 24 hours to allow any salts in the metal to sweat to the surface. A test for chloride contamination should be performed. The procedure should be repeated until chloride concentration on the surface is below 40 ppm.
5. Mix 4 part resin to 1 part hardener by volume (7.25 to 1 by weight) or transfer entire kit onto a clean and dry mixing surface and mix thoroughly until color is consistent.
6. Apply fully mixed material to prepared surface.
7. If using to rebuild shaft, the following applies:
NOTE:
● Machine the worn area down 3mm (0.125 in) to produce a square shoulder on part. The material is stronger with a square edge versus a feathered edge.
● Machine a spiral cut in bottom of area to be repaired to provide mechanical keying into surface.
● Apply excess product to ensure small shrinkage during cure does not produce depression.
● Machine the surface to original dimensions prior to full cure, as the product is very wear resistant.
Storage:
Store product in the unopened container in a dry location. Material removed from containers may be contaminated during use. Do not return liquid to original container. Storage information may be indicated on the product container labeling. Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Henkel cannot assume responsibility for product which has been contaminated or stored under conditions other than those recommended.
