Success Stories

Mascot Marine-DTM Spray-On Thermal Insulation 5 Gallon BucketMascoat Marine-DTM coating is a water-based, one-part coating comprised of air-filled particulates held in suspension by an acrylic binder. It applies like paint and is maintenance-free, providing a thermal barrier and anti-condensation capabilities for shipboard construction.

Currently, Mascoat Marine-DTM anti-sweat coating is in use on thousands of marine vessels from Alaska to Antarctica, from yachts to workboats. This coating can replace or work in conjunction with most blanket and foam insulation products. This can result in substantial reduction of weight and keeping the vessel within the new stringent marine codes and classifications.

Mascoat vs. Conventional Insulation

The coating employs the best water-based coating technology and contains no harmful elements. Mascoat Marine-DTM bonds directly to the substrate or primer, leaving no room for corrosion to take hold. Direct bonding gives the coating the ability to protect your vessel without degradation of the substrate for many years to come. By using Mascoat Marine-DTM coating system, you can rest assured that your vessel is protected and that the interior accommodations will be comfortable.

Best of all, the coating is extremely lightweight. This allows easy application around difficult areas such as stiffeners and other tight areas without adding excess weight. Read our Mascoat Success Stories to see specific applications where Mascoat was able to deliver excellent cost savings and protection.


Cross Section Mascoat Marine-DTM

Since the coating applies rapidly, labor and construction time-frame savings escalate by using Mascoat Marine-DTM. This means that your normal thermal barrier methods can now be performed by in-house painting crews instead of using subcontractors. Productivity will increase and gives the customer a better product in a shorter time frame.

An added benefit is the sound reduction or soundproofing vessels of airborne structural noise. By using Mascoat Marine-DTM your vessel automatically becomes quieter by reducing structural noise. Our product is capable of a 1-3 dB drop in airborne structural noise or a 28 SRC factor (for more about decreasing sound in vessels, please see our sound damping coating Mascoat Sound Control-dB sound damping coating.)
