Operation
1, Place 518A and 518B at the temperature of 15 to 25 ℃, relative humidity lower than 70% for 12hours.
2, Well prepared the products you need to apply the 518AB such as the PVC signage/nameplate, metal signage/nameplate, put them into the oven to heat at the temperature of about 60℃ to clear the moisture on the surface.

4, Weigh the 518A and the 518B by 1:1, and fully stir it.
5, Clear the bubbles by vacuum machine(the mixture will not have bubble at the -0.1 vacuum)
6, Take a clean syringe to draw the mixture and drop it to the surface of the well prepared signage/nameplate. Normally the thickness is 2mm.
7, Look at the glue in 5 minutes, if there is some bubbles, use a pin to break the bubbles, or if there is some area that has not been covered by glue, use the pin lead it.

Caution
1,The operating environment should be ventilative and should keep away from fire. Closely sealed after use.
2, Avoid eye contact, in case of contact, wash with plenty of water and get medical attention immediately.
3, If contact skin, wrap with clean cloth or paper, and wash it with water and soap.
