  APPLICATIONS
1. Vehicle bodies and cab construction including panels, underbody components, and roofing.
2. Front and rear spoilers, auto trim, moldings, body seams, and welded joints.
3. Waterproofing exterior lap seams in many applications, including truck trailers, RV's, metal roofs, window  perimeters, grain bins and HVAC units.
4. Waterproofing rivet seams.
5. Sealing of exposed and concealed joints of aluminum, steel, coated metals, wood, roof rails, and door hinges in transport equipment.
6. Sealing and caulking expansion joints, pre-cast concrete panel joints and joints between logs on log homes.

PROCESS
Cleaning:
Clean surface with a strong jet of compressed air, sandblast, or solvent to ensure the surface being clean, dry, free of oil, grease, and of sound quality.
Activating/Priming:
Activators and/or primers may be required to achieve optimal adhesion depending on the nature of substrates.
Application of sealant:
Cut tip to desired shape and size. Puncture airtight seal. Install with hand or power operated gun and extrude the sealant into the joint. Clean excess sealant using hard rubber plate or finger wet with soap solution.

PACKAGING
310ml cartridge, 600ml sausage

STORAGE AND SHELF LIFE
When stored at the recommended conditions in original, unopened containers, this product has a shelf life of 9 months.
The shelf life of polyurethane sealant is related to the temperature and humidity of the environment. The recommended storage temperature is 5-25°C, humidity is <50% RH. It is strictly prohibited that the transportation or storage temperature is over 30°C or the humidity is over 80% RH. And high-temperature container transportation is prohibited as well. In the long-time high temperature and high humidity storage environment, the product is easy to get viscous, extrusion will be deteriorated and shelf life will be shortened.
