Mascoat 400DFP is the preferred primer for applications that are higher than 250˚F (121˚C). Our thermal insulating coatings are designed to work on substrates up to 350˚F (177˚C), sustained with peaks up to 375˚F (190˚C), and this primer is suitable on applications up to 400˚F (200˚C).
Mascoat 400DFP is dry-fall product within 10-20 feet (3-6 meters). It is exceptional in the field because it does not require an additive or reducer to achieve its dry-fall properties. The one-part product with no pot life is ready to spray out of the pail and does not risk overspray on vehicles or buildings near the application site, though a reducer may be needed in extreme cold or hot ambient conditions.
The product can be applied via spray, brush or roll methods, giving the contractor and client more choices on how to achieve their goals. It is light yellow in color which offers the distinct advantage for contractors to not see shadows. That means that the person spraying can tell when they have achieved the desired thickness of 2-4 mils without the need for a wet mil gauge, though Mascoat always recommends quality assurance measures be taken.
Other manufacturer coatings that work in this temperature range experience reduced flexibility at higher film builds, however Mascoat 400DFP retains its flexibility, ensuring that it will remain adhered to the substrate through all hot/cold cycles. The primer does require equipment to be out of service during application, but it is ready to recoat within just 1 hour and the equipment can be brought back into service in only 12 hours. Since thermal insulating coatings can be applied to hot surfaces, the system ensures minimal downtime for facilities.
