Belzona® Corrects Hatch Seals

 
 

Industry:

Marine (MRNE)

 
 

Application:

Solids Handling Machinery (SHM)

 
 

Customer Location:

Ship Dockyard, Bulgaria

 
 

Application Date:

July, 2007

 
 

Application Situation:

New rubber seals for cargo ships hatch covers.

 
 

Problem:

Five new sets of seals supplied were short in length and therefore did not fit the hatches correctly. 

 
 

Products:

Belzona® 2211 (MP High-Build Elastomer)

 

Substrate:

Rubber

 
 

Application Method:

Application was carried out in accordance with a modified version of Belzona Know-How System Leaflet SHM-3. Each rubber seal was cut at angle of 45 degree and between two parts the additional piece to correct the lenght was inserted. For better joint strength additional rubber strips were cut and bonded inside of the hatch seal pieces. All pieces were assembled and kept together by help of metal templates and clamps until complete cure of the applied Belzona® 2211.

 
 

Belzona Facts:

Belzona solution allowed the customer to save both time and additional expense for new rubber seals delivery. Alternative repair by hot vulcanization required special equipment and would be time consuming. Belzona provided a quick effective repair without heat and using available equipment. Delivery of new rubber seals would cost at least $5,000 while Belzona repair was $700 and avoided costly delays in dock.
