This low density, two-component, manganese dioxide cured liquid polysulfide polymer system that is suitable for use in fuel tank, fuselage hole filling, cavity filling and fuel tank filleting applications. It has outstanding resistance to jet fuel, as well as resistance to chemicals and petroleum products common to the aircraft industry. AC-645 Class B maintains its flexibility and bond strength on most metal substrates such as aluminum, titanium, steel, stainless steel, and many coatings under the extremes of temperature, weathering and stress. The mixed compound is a thixotropic paste easily applied by extrusion gun or spatula. It has excellent tooling properties.

If the item that you are trying to ship is deemed Hazmat you may have an additional fee added to your order when you check out. Items are deemed Hazmat as per the Section 14 Transport Information located in the item's Material Safety Data Sheet (MSDS). Sorry, but things that can go "boom" are hard to ship and we have to pass on our fees.
Flammable or explosive items such as Fire Extinguishers, MEK, Toluene, Paint Thinner, etc. are subject to a $25.00 Hazmat fee via ground shipping methods. However, the majority of Hazmat items have no fee when shipping with a ground method.
Most Hazardous Goods are subject to air and international transport fees. This fee is $40 for domestic air shipping methods and $80 for international shipping methods.
