Low friction coating

Two component, solvent free, pigmented polyamide cured epoxy, modified to improve slip factor.


Lining of surfaces to prevent build-up of low abrasion materials, particularly in feed meal silos.

  • Brush applied low friction lining
  • Greatly reduces build-up problems when storing fine powders, meal etc
  • Allows free flow of materials along coated surfaces
  • Easy to apply
  • Economical

Surface Preparation

Steel should be grit blasted to a minimum standard of Sa 2 . on the Swedish Code of Practice SIS 0 55900.

Concrete should be free of all laitance and preferably should be lightly abrasive blast cleaned. All blemishes in the surface such as pop-outs, omegas, blowholes and honeycomb should be patched with epidermix® 201. This should be left overnight to dry and should be sanded smooth. Over-coating of epidermix® 201 should be carried out within 48 hours. All debris of preparation must be completely removed.


Steel should be primed with a coat of abecote® 384. If maximum smoothness of coating is required this may be overcoated with a coat of abecote® 386 which should be rubbed down after drying overnight. Concrete should be primed with a coat of abecote® 386. If maximum smoothness of coating is required, a second coat should be applied the following day, left overnight and then rubbed down. All debris of rubbing down must be completely removed.


Stir contents of each container very well.

Add the Activator to the Base and stir together for at least 5 minutes using a flat paddle. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 rpm) fitted with a paddle.

If only part of a kit is to be used, add one volume Activator to two volumes Base. Measuring must be accurate and separate stirrers and containers used for proportioning each component.


abecote® SF 321 must be applied to the primed surface within the over-coating time stipulated for the specific primer.

Application may be by brush or short fibre roller.

To achieve optimum finish the first coat of abecote® SF 321 may be rubbed down and then over-coated with a second coat.

At least seven days must elapse between applying the last coat and putting the installation into service

Shelf Life

Two years from date of manufacture. 


5 L dual pack tins.
