Make sure the mating surfaces are clean and free of grease.

Apply a thin coating to the mating surfaces and assemble. Do not thin the product.

Torque follows T = K x F x D, where K is the torque coefficient, F the clamp force and D the bolt diameter. Use a dust mask when grinding or wire brushing.

Storage and handling

Store the unopened container in a dry location, optimally between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.
