Texas City, Texas --- Brazos Urethane Inc. a well known spray polyurethane foam (SPF) roofing, insulating and waterproofing business, was recently askled by the US Navy to help with an insulation and waterproofing system for a radar dome mounted aboard a ship.
The project was carried out on the Texas coastline under adverse weather environments, said a Brazos Urethane statement. The company used SPF insulation as the primary coating for the radar dome for its ability to withstand the extreme vibration, movement and severe weather conditions found at sea.
Not only was SPF applied to the radar dome, it was also used to insulate satellite and communication equipment aboard the ship. As well as SPF, the application use of polyurea and an aliphatic urethane top-coat.
Because the radar dome is designed to move rapidly in all directions, Brazos had to apply SPF to tolerances of + or - 1/8 inch (ca 3mm). The specifications required SPF from 2" to 0" in thickness, protected by 80 mils of high density polyurea coating and top coated with 6 mils of aliphatic urethane coating. Along with dealing with adverse weather conditions on this project, Brazos Urethane had to adhere to military rules and regulations.
Brazos completed the job in 15 days with positive feedback from the crew, and in the process gained a nomination for the 2011 SPFA (Spray Polyurethane Foam Association) Industry Excellence Awards.
