MIXING INSTRUCTION
1.
Pre mix Epusil U 300 in the original container.
2.
Weigh out the required amount of part A.
3.
Weigh into 100 parts of Part A 50 parts of Part B.
4.
Mix thoroughly scraping both sides and bottom of the
mixing container considering the short creaming
time. Because of the short creaming time a
mechanical mixing system is preferred.
5.
Pour into mold.
