Permanent Cooling Tower Repair –
Cooling Towers are notorious for leaking due to chemical attack and extreme climate issues. These problems will consequently lead to corroded surfaces that cause leaks. The following information is an informative guide to illustrate how to repair leaking cooling towers. PANSEAL will permanently stop leaks and, in fact prevent future corrosion in metal or stainless steel surfaces. Additionally, PANSEAL is the HVAC leading product for cooling tower repair.
PANSEAL Cooling Tower Repair
PANSEAL Cooling Tower Repair is the industry leading product for sealing leaks and protecting cooling towers. Cooling Towers are notorious for leaking due to chemical attack and extreme climate issues. These problems will consequently lead to corroded surfaces that cause leaks. The following information is an informative guide to illustrate how to repair leaking cooling towers. PANSEAL will permanently stop leaks and, in fact prevent future corrosion in metal or stainless steel surfaces. Additionally, PANSEAL is the HVAC leading product for cooling tower repair.
Preparation Prior to Coating
Rule of Thumb: PANSEAL works on rusted surfaces and will encapsulate rust, however a clean, profiled surface allows optimum adhesion strength.
* PANSEAL is designed to perform well even when surface preparation is less than ideal, but to get the best results, refer to the following recommendations.
Implements for Abrading:
Sandblasting is indeed an optimum preparation technique, but on the contrary it requires equipment and as well as time consuming clean-up.
Grinders, or wire wheels can also achieve ideal profiled surfaces. We recommend using an abrasion wheel. A lesser abrasion wheel may only polish the surface. Polished surfaces will make it slick and hard to adhere to.
Pressure Washing is ideal for cleaning the surface after preparation. Some projects may only require pressure washing and still be adequate for the coating to adhere well.
PANSEAL Preparation According to Surface Type
Metal, or Galvanized Surfaces: PANSEAL will adhere well to these surfaces with minimum preparation, but again a profiled surface is recommended for optimum adhesion strength.
Use grade 80-150 abrasives for steel and materials resistant to scoring. We recommend using 300-600 grade abrasives for light alloys and less resistant materials. Remove all oil, grease, or scale from the surface. Stainless Steel: An etched profile is needed due to the slick nature of stainless steel. Eliminate grease with trichloroethylene if necessary. Mechanically abrade stainless surface.
Concrete: New concrete must be cured a minimum of 7 days at 75°F (24°C) and 50% relative humidity or equivalent. Prepare surfaces in accordance with ASTM D4258 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete. PANSEAL Paste Grade in addition is ideal for filling voids in concrete. These voids may require re-surfacing in order to strengthen and seal these areas. Mortar joints should be cured a minimum of 15 days for cooling tower repair, or other coating projects.rfaces with a grinder or similar tool and clean.
PANSEAL Application
How to mix PANSEAL: First mix Resin (part A) and Hardener (Part B) separately In order to obtain an ideal blend of the liquids and solid contents. Then mix part A and B simultaneously and continue mixing to ensure uniform color and viscosity. Pay close attention to the sides and bottom of the container.
Are Primers Needed for PANSEAL? No primers are needed for metal or stainless steel surface repair. However, for concrete surfaces we recommend DX-1100 primer. DX-1100 is ideal for preventing out-gassing and additionally increase the adhesion strength of PANSEAL to the concrete.
How to apply PANSEAL: PANSEAL can be applied by brush, roller or sprayer. Make sure to see the PANSEAL Product Data info for spraying recommendations.
What is the Coverage for PANSEAL? 1 PANSEAL Gallon will cover 160 square feet at 10 mils (recommended minimal thickness). Most applications will cover 80 square feet at 20 mils thickness (or more) due to the thick viscosity of the product.
What Makes PANSEAL Great?
- NO VOCs, Safe to Apply
- Very Minimal Odor – Ideal for Schools and Hospitals
- Coverage – 80 Square Feet at 20 mils Thickness
- Seals Leaks Immediately, Prevents Corrosion Permanently
- Works on Metal, Fiberglass, Stainless, Concrete and Wood
- Minimal System Down Time
- Excellent adhesion strength – 2,750 psi (pull-off adhesion test ASTM D 4541)
- Extreme Chemical Resistance and Temperature Range Properties
ELASTASEAL Flexible Coating Repair
If a flexible coating is required, refer to this link to ELASTASEAL All Purpose Flexible Coating.
PANSEAL is not ideal for areas of heavy vibration or extreme expansion and contraction. ELASTASEAL is the best product if the surface is not well supported underneath and there is a possibility of flex while walking on the surface (trampoline effect). This is why ELASTASEAL would be more ideally suited for this type of surface due to its high flexibility.
ELASTASEAL is also used as an all -purpose coating and sealant, but due to it’s greater than 300% elongation, it is ideal for areas of heavy vibration or expansion and contraction. Additionally ELASTASEAL’s adhesive strength is 1600 psi. It’s chemical resistance properties are well suited for many applications. ELASTASEAL’s strength and durability rank above the best flexible, industrial coatings while exhibiting characteristics of very minimal odor and NO VOCs.
