Usage





Applicaiton

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 homogenised prior to use. 
The two components should be thoroughly mixed using a weight ratio of 1:1 until the mixture has a uniform colour. 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.
