Description:

Ship Launching Grease System. 

Applications:

• Base Coat and Slip Coat launching greases are premium products offering several features and benefits to shipbuilders and offshore drill rig builders.
• Base Coat and Slip Coat greases are designed specifically for launching ships, offshore drill rigs, etc., on sliding ways. A one-quarter(1/4) inch layer of Slip Coat on a one-quarter(1/4) inch of Base Coat will support twenty-five tons per square foot. Dynamic coefficients of friction range from 0.025-0.035 depending on the declivity and loading.
• To use the Base Coat and Slip Coat system, the ways must be cleaned of previous coating or lubricants prior to applying the Base Coat. The Base Coat can then be applied and allowed to cool. Once cooled, the Slip Coat is spread on top of the Base Coat. 

Advantages:

• Base Coat has a high melting point (160o F)and will not bleed or melt at ambient temperatures. It withstands very heavy loads and will protect steel ways against rust & corrosion. Base Coat is very adhesive and will resist extrusion, squeeze out, cracking, and lift. This product can usually be 50%-90% reclaimed and used again.
• Slip Coat is impervious to salt and fresh water and will not wash off in rain or tidal changes. It has a very low coefficient of friction, easily launches on low-declivity ways, and reduces way end-pressures.
• This system does not contain the old, inefficient technology of tallow mixed with stearine or stearic acid followed by a soft soap overlaid with lard oil. No rosin, tallow, or other fillers are added. Typically, 30%-40% less grease is needed than traditional ship launching products.
