Q: Does Metal Shield sag at high temperatures?
In test run according to Mil Spec C-0083933A, No sagging or flow of Metal Shield occured at temperatures up to and including 300° F
Q: Does Metal Shield support flame?
Test show that Metal Shield may char but does not support combustion for more than 15 seconds after the flame source is removed. Tests were performed according to Mil spec C-0083933A using a flame from an acetylene tourch.
Q: What are the benefits of the Insulating ceramics?
very resistant to thermal shock and are used in applications such as ovenware, stove tops and kilns
Below are just a few examples of how important ceramics are to society.
Ceramics play an important role in addressing various environmental needs.
Ceramics help decrease pollution, capture toxic materials and encapsulate nuclear waste. Today's catalytic converters in trucks and cars are made of cellular ceramics and help convert noxious hydrocarbons and carbon monoxide gases into harmless carbon dioxide and water. Advanced ceramic components are starting to be used in diesel and automotive engines.
Ceramics light-weight, high-temperature and wear resistant properties results in more efficient combustion and significant fuel savings.
Reusable, lightweight, ceramic tile make NASA's space shuttle program possible. The 34,000 thermal barrier tiles protect the astronauts and the shuttles aluminum frame from the extreme temperatures (up to approximately 1600°C) encountered upon re-entry into the earth's atmosphere. See How they work
Q: Has any "real world" testing been done?
Two automotive grade steel boxes were constructed with one end open so as to trap road contaminates. They were coated with Metal Shield and mounted on test vehicles, open end forward. The test vehicles were driven in regular service for two winters and one summer and after 18 months exposure on the underside of the vechicles the boxes were 100% rust free.
Q: On autos, were should Metal Shield be applied?
For the optimum heat reduction we recommend applying to the firewall, undercarriage and wheel wells.
Q: How much Insulating Metal Shield do I need?
This will vary depending on the thickness applied. We recommend 6-8 Mils per coat which will yield appx 150 sq ft per gallon. Metal Shield can be applied up to 20 mils thick for additional soundproofing and insulating properties with no sagging or running.
Q: Can Metal Shield be sprayed?
Yes, being Thixotropic, Metal Shield sprays evenly at high and low temperatures with little change in low air pressures at the tip. Using Airless spray we recommend .017 - .019 tips size and pump pressures of 1300-1500 psi. conventional spray equipment use 10-15 psi fluid pressure and 50-60 SPI atomizing pressure.
Q: Do I have to remove All existing rust prior to applying?
No, Metal Shield is intended for use as a field applied maintenance coating and does not require complete removal of rust or previously applied lead based coatings on bridges and other steel surfaces.
