HOW TO USE

*Liquid B can occasionally exhibit turbid on storing. This is due a precipitation of the resin component, not a quality deterioration. When this occurred, heat the Liquid at around 70-80degC for 2 hours to clarify,cool down to room temperature before use.

*Remaining AE-70-M11HF is easily removed or cleaned up from screen by using usual thinner like toluene, ethylacetate, or methyl ethyl ketone.
