Hye everybody,

i’m a french user and i have a question

Can i use MG Chemicals 832H like loctite marine epoxy

  • Convenient 1A:1B volume mix ratio
  • Low mixed viscosity of 4 100 cP
  • Extremely high compressive and tensile strength
  • Excellent adhesion to a wide variety of substrates including metals, composites, glass, ceramics, and many plastics
  • Excellent electrical insulating characteristics
  • Broad service temperature range -40 to 150 °C (-40 to 302 °F)
  • Extreme resistance to water and humidity (allows for submersion where needed)

@Korrigan,

I noticed that the description of the 832HD indicates that is is “hard” and you might want to find an epoxy that is more pliable. The Loctite Marine Epoxy does get hard like the 832HD and I believe that BR has switched to a more pliable epoxy that is black and not cream colored like the Loctite Marine Epoxy.

Actually I believe the black one is just for a smooth finishing ending, if you take a look at the other side it is still white coloured like the marine epoxy.

@luisgamez,

I believe that BR is using the Loctite Marine Epoxy on the WTC side of the cable penetrator and a less hard (more pliant) black colored epoxy on the environment side of the cable penetrator.

You confirm that MG 832H is like loctite marine epoxy ?

BR wwould have an opinion

Hi @Korrigan,

We’re currently in the process of changing over to a penetrator potting method. In the past, we have used a two step process of Loctite marine epoxy with a similar black epoxy on top for purely aesthetic reasons. The 832H epoxy has similar properties, but it is much runnier, so you may have trouble with it dripping out the bottom during potting. The marine epoxy is probably closer to 30,000-50,000 cP. The key is the epoxy needs to adhere well to both the anodized aluminum of the penetrator and the polyurethane jacket of the cable. Proper surface prep makes a big difference, but beyond that there isn’t too much limiting to specific epoxies, at least to moderate depths.

The newer epoxy we have been shipping products with for the last couple weeks is a new formulation that is more flexible and otherwise higher performing, we will have more details and a new potting kit in the future.
