Usage


Application

It is supplied in lot-matched kits consisting of Part A and Part B in separate containers. 
During long periods of storage, some of the filler may settle at the bottom of the containers and should be individually homogenized before use. 
The two components should be thoroughly mixed using a weight ratio of 1:1 until the mixture has a uniform color. Vacuum de-airing is recommended. A residual pressure of 10-20 mm mercury applied for 5-10 minutes will sufficiently de-air the material.Package
Part A: 25kg/barrel,200kg/Drum.
Part B: 25kg/barrel,200kg/Drum.
