LOCTITE® PC 7383
Features and Benefits
This black, two-part polyurethane coating is used to repair or replace liners and protect equipment from abrasion, impact and chemical attack.
LOCTITE® PC 7383 protective coating is a room temperature curing coating that is easily applied with a trowel or spatula. This innovative formula bonds well to both rubber and metal, making it ideal for repairing liners. This formula also allows for thicker coatings on vertical and overhead surfaces, without any sagging or slumping. It is recommended for use on processing equipment that is exposed to both abrasion and impact and is suitable for dry service temperatures of between -20°C to 80°C.
- 100% solid - no sagging or slumping
- High abrasion, impact and chemical resistance
- Protects both rubber and metal surfaces
- Easy to use - trowelable and thixotropic

How to
Step by Step Guide
1. Preparation - Metal Surfaces
Remove dirt, oil, grease, loose flaky rust, etc., with a suitable high pressure water cleaning system using LOCTITE SF 7840 cleaner/degreaser.
2. Preparation - Rubber Surfaces
Remove all loose and damaged pieces of material from the repair surface such as old rubber, fabric, etc. Abrade the repair area with an abrasive wheel, being sure to avoid overheating and melting of the rubber.
3. Mixing
A corded drill with mixer attachment can be used for mixing. Pre-mix the resin for 1 minute. Add the hardener into the resin and mix thoroughly until there is a uniform color and consistency. Be sure to scrape the sides and bottom of the pail.
4. Application
Apply a thin amount of the coating onto the repair area and work the product into the surface with a trowel, spatula, or gloved hand, to ensure good adhesion and to avoid bubbling. The coating can then be built up to the desired thickness required.
Frequently Asked Questions
Why is surface preparation so important?
Will my 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 it 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?
How quickly can I put my equipment back in service?
