250P

Mascoat 250P is a 2-part epoxy with aluminum pigmentation. It is appropriate for temperatures up to 250˚F (121˚C), an extremely common temperature for insulating coating applications.  The aluminum pigmentation sets it apart from many other epoxies and is important for a few reasons:

  • The aluminum provides additional plating, creating a treacherous path through the film for moisture ingress and enhancing permeability characteristics. These qualities greatly increase the coating’s ability to prevent corrosion.
  • The pigment increases surface tolerance which gives the coating better adhesive properties and ensures a long lifespan once applied.
  • Although the primer is designed to be topcoated with an insulating coating, it can also be used as a standalone because the aluminum decreases the rate of chalking.

Surface preparation on large scale maintenance applications like tanks is crucial but not always executed perfectly, especially in areas where blasting is not allowed. Mascoat 250P is ideal for these situations, as it is easily applied to marginally prepared surfaces that have been remediated with hand tools. Its 1:1 mixing ratio, good pot life at 4 hours in 75˚F (24˚C) and ability to be applied via spray, brush or roll methods make the coating a breeze to work with for contractors on applications of all sizes. The simplicity reduces mistakes and labor hours, shortening application times and decreasing headaches for plant and contractor personnel.

Sometimes unforeseen events can cause delays in application. 250P has a 30 day recoat window. This means if a job has to stop for a few days or weeks after the application has begun, there is no need to go back over previous work. The primer also has wonderful flexibility, which is extremely important on storage tanks due to expansion and contraction concerns.
