This document summarizes innovative repair solutions from HEI for mechanical equipment, piping, valves, pumps, and concrete structures using 3M Scotchkote products. It discusses shaft, keyway, bearing housing and pin bushing repairs for mechanical equipment as well as emergency leak repairs, valve repairs, pipe lining, and pump repairs. Concrete repair solutions are highlighted for structures and chemical containment. Seamless floor systems and non-skid surface coatings are also mentioned. Training and technical support is available for all applications.

3. Mechanical Equipment Repairs Shaft Repairs – Machined Metal-Tech EG is applied while the part is in the chuck. After it sets up (about 2 hours) it is machined back to size.

4. Mechanical Equipment Repairs Shaft Repairs – Using the Former ( split sleeve) Technique Machine a split sleeve (can be made from any rigid material). The I/D of the sleeve is to be the same as the O/D of the shaft. 1/8” weep holes are drilled in the sleeve every 3 – 4 inches. Release agent is applied to sleeve. Metal-Tech is applied to both shaft and sleeve and sleeve is clamped in place. Shaft is damaged, disassembly is difficult or impractical. Repair in place is attractive. Remove old bearing and other obstructions. Prep the shaft with grinders. Leave surface as rough as possible. Once the Metal-Tech material has cured ( 2 to 4 hours), the sleeve is removed. Parting lines and nubs from the weep holes are cleaned up with emery cloth and the shaft is ready for reassembly.

6. Mechanical Equipment Repairs Advantages to Polymeric Repair Systems No heat distortion, stress or metallurgical changes to substrate material. Our materials are based on resilient resin systems which allow the same product to be used on multiple substrates. This also makes our materials able to withstand vibration, impact and thermal movement better than other systems. Effective on any substrate (aluminum, cast iron, stainless…) No special equipment required. Easy application Can be done in place Minimal downtime Cost effective

7. Piping & Valves Emergency Leak Repair Leaks occur without warning and never at a good time or place. Our materials allow for quick, durable repairs that can get you to the next outage or, in many cases are permanent repairs.

8. Piping & Valves Valve Repair Corrosion, abrasion and general wear can be repaired and prevented. Valve seats can be repaired with excellent results.

9. Piping & Valves We have excellent materials for lining pipes as well as for exterior protection

10. Pumps Nearly 25% of industrial electricity demand comes from industrial motor systems Over 50% of pump life cycle costs result from energy and maintenance expense Less than 15% of pump life cycle costs are initial purchase costs Energy savings of 20% or more are possible with systems optimization

11. Pumps Pump repair and optimization are a major focus for our business. With 30 years of experience in pumps and related equipment, we can help you trouble shoot and resolve many pump problems.

12. Pumps Cerami-Tech EG: Repair general wear, abrasion and corrosion damage. Cerami-Tech CR: Improve pump efficiency thru reduced internal friction loss. Corrosion resistant and durable. Cerami-Tech FG High performance abrasion and corrosion resistance. Broader chemical and temperature tolerance. Cerami-Flex FG Flexible lining system designed for cavitation and abrasion resistance.

13. Pumps Pump repairs can be done in house by your personnel or off site in our approved pump shops. We provide training and support for every application.

14. Concrete Repair Concrete is considered a permanent construction material and yet it is constantly degraded by exposure to the environment, movement of the earth and man made stress. We have a variety of materials designed to make durable repairs to all types of concrete structures.

16. Concrete Repair Floor-Tech PR Fast setting, self priming concrete repair for small patch jobs and low temperature repairs. Floor-Tech RS Resurfacing screed for flat areas and minimal thickness vertical repairs. Ideal for resurfacing badly pitted or agrigated floors. Grano-Tech High performance concrete repair for high stress applications. Wall-Tech LW Light weight concrete repair for vertical and overhead repairs.

17. Concrete ProtectionChemical Containment We offer a broad range of specialty coating for primary and secondary chemical containment of both acids and caustic in high concentrations. Almost any industrial chemical can be addressed by our range of product.

18. Seamless Floor Systems We offer a broad range of seamless floor systems. Water based, solvent free, 100% Solids, epoxy and polyurethane based systems are all available. We will work with you to select the right system for your specific application. These systems are safe and easy to use. They can be applied by in house crews or by our approved contractors. We provide on-site training and technical support for everything we sell.

19. Non-SkidPositive Grip Systems By incorporating an appropriate aggregate into our resin systems, we can create positive grip systems for a variety of purposes. Non-skid aggregate can be added to any one of our floor systems to produce greater traction where it is needed. The rolls above are coated with Metal-Tech FG and then aluminium oxide grit is applied to provide positive grip on these break testing rolls. The same system is applied to lumber mill rolls for more efficient movement of lumber thru the mill.
