What is the Adhesive (Marine) - What is a marine adhesive??

Accepted Answer

At Label Planet  we use this term to refer to the permanent adhesive used to make our waterproof marine labels    MWP      MWPE      MWPO      MWPP     which is a clear acrylic-based permanent adhesive that is BS5609 part 2 approved  BS5609 is a standard that lists the requirements that must be met to ensure that a label fits the criteria for use in marine and extreme environments  The most common application for this type of label is chemical drums that are used to store waste  and are shipped overseas   if one of these drums were to fall overboard  the label MUST remain in place so that the contents remain identifiable as dangerous waste  Companies who are transporting dangerous goods overseas are subject to a number of safety regulations  e g  Merchant Shipping Regulations  the International Maritime Dangerous Goods  IMDG  code  and or the Globally Harmonised System of Classification  GHS   among others   which will require that the labels applied to these goods meet the British Standard BS5609  which is an internationally recognised standard for labels that are to be used on goods that will be shipped overseas             The BS5609 standard is a multipart certification also known as the    Marine Immersion Testing    standard  Sections 2 and 3 of the certification list the requirements and testing methods that are used to determine if the face material and adhesive used to make a label  part 2  and the printing inks  ribbons  toner  and or printing systems used to print a label  part 3  are suitable for use in marine conditions  A printed label CANNOT be tested under section 3 of the standard unless the label itself has already met the requirements of section 2             Part 2 tests the durability and permanence of the face material and adhesive  testing includes accelerated aging tests  such as exposure to artificial weather to simulate salt spray and sunlight  to test dimensional stability  colourfastness  and resistance to weather   temperature cycling  exposing the labels to high and low temperatures for sustained periods of time   and adhesion tests  which include applying the labels onto test blocks that are then left in sea water at mid-tide for three months             Part 3 likewise tests the durability of the print that is added to the labels  testing takes place using a specific set of printing inks  toners  or ribbons and a specific printing system  It includes tests for print key effectiveness  by testing resistance to print removal using adhesive tape   abrasion resistance and print legibility  by exposing the label to a mixture of sand and artificial sea water   print permanence and colourfastness  by exposing the label to artificial salt spray and sunlight   Similarly to part 2  the printed label must also be able to undergo three months submersion in salt water conditions             While the BS5609 certification can be used to certify that labels are suitable for highly specific applications  such as chemical drums   it is also used as a general indicator that a particular label product is extremely robust and durable and therefore suitable for a range of applications that may include exposure to unusual conditions  for example  labels that are to be used outdoors   At Label Planet  our MWP  MWPE  MWPO  and MWPP label ranges are all made with a marine adhesive and have been successfully tested according to the requirements of BS5609 part 2             Here is the Harvard-style citation to use if you would like to reference this definition of the term marine adhesive     Label Planet  2016    What is a marine adhesive    Marine Adhesive Definition    Available at  https   www labelplanet co uk glossary adhesive-marine   Accessed  January 1  2023
