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 Natural Blue® 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.
Frequently Asked Questions
Why is surface preparation so important?
Will cure time be affected if I bring in a cold part from outdoors into a warm room?
If I add more hardener, will that make the product cure faster?
Can I add solvents to make the product thinner (easier to work with)?
Can I mix just the amount I need instead of the entire amount of the composite?
When can I put my equipment back in service?
