LOCTITE PC 7226 Fine Particle Wearing Compound is a grey, two-part, trowelable, carbide-filled, epoxy-based wear protection coating that effectively protects equipment from fine particle abrasion.
LOCTITE® PC 7226 Fine Particle Wearing Compound is a two-part system designed to provide processing equipment with a protective surface coating against fine particle abrasion (with or without chemical attack) on a wide range of applications. It can be used overhead or on vertical surfaces and is suitable for use in service temperatures ranging from -30°C – 120°C. Typical applications include chutes, ducts, elbows, transitions, pumps, fans, hoppers, and cyclones.
  • Protects against fine particle abrasion
  • Trowelable - easy to mix and apply
  • Can be used on overhead or vertical surfaces
  • Prolongs equipment life

How to

Step by Step Guide

1. Preparation - Cleaning

Remove dirt, oil, grease, loose flaky rust, etc., with a suitable high pressure water cleaning system using LOCTITE® SF 7840 cleaner/degreaser.

2. Preparation - Blasting

Blast all surfaces to be coated, with a sharp edged angular grit, such as aluminum oxide, to a depth of profile of approximately 75 microns, and a degree of cleanliness of Very Thorough Blast Cleaning/Near White Metal (ISO 8501-1 SA 2½ /SSPC-SP 10).

3. Preparation - Cleaning

After blasting, metal surfaces should be cleaned with a waterless, or solvent based LOCTITE® cleaner, such as LOCTITE SF 7611 or SF 7633, and allow the surface to dry before application of the product. Coat the surface before any oxidation or contamination takes place.

4. Preparation - Protection from Flash Rusting

To avoid flash rust, repairs should be made as soon as possible or within a maximum 2 hours of blasting. Otherwise, apply a thin coat of LOCTITE SF 7515 to all surfaces and allow to react for 1 minute. After 1 minute, blow off with clean and dry compressed air until the surface is completely dry.

5. Mixing the Material

Measure 2 parts resin to 1 part hardener by volume or weight if doing a partial kit. Otherwise, mixing a full kit is pre-measured at the correct ratio. For a full kit mix, a spiral mixing blade attached to a high torque electric or pneumatic drill can be used. For a partial kit, transfer measured quantities onto a clean and dry mixing surface to mix together with a trowel until uniform in color. If resin and hardener temperatures are 15°C or below, preheat resin only, to about 30°C but not to exceed 40°C .

6. Application

Apply fully mixed material to the prepared surface. Initially apply the material in a very thin layer to "wet" out the surface and ensure full epoxy contact with the roughened surface. Build up to desired thickness (minimum 6 mm), avoiding air entrapment. At 25°C, the working time is 15 minutes and functional cure time is 4 hours. Working and cure time depend on temperature and mass - the higher the temperature and the larger the mass, the faster the cure.
