① Prepare the container and clean and dry labeling.

② will need to use the crystal glue A and B two components in the ratio of 3:1 weighing good (A glue 3 B glue 1), the A group heated to about 40 ℃ and then added to the B group, poured into the container, stirring evenly, eliminating bubbles (vacuum, vacuum pump model 2X-4. Specifically, see the schematic diagram.) 1# for the empty bottle, play a role in protecting the vacuum pump.

2# for the storage of crystal glue to be defoamed.

1#2# are filtering bottles (purchased from glass instrument stores around)

③ After defoaming the glue with a small beaker or syringe, etc. evenly dripped on the sign, such as the edge of the sign crystal glue trickle (basically can go), the available small needle toggle, so that the glue coated uniformly on the surface.

④ Gel curing: coated signage, gel time is about 3 hours at room temperature 25 ℃; curing time is about 36 hours at room temperature. Or put the coated sign into the constant temperature drying oven at 60℃ for 3 hours that is fully cured.

⑤ If the customer has special requirements, the gel curing time and the softness and hardness of the gel after curing can be adjusted according to the customer's requirements.

6 The amount of glue can be controlled by the customer, and the remaining glue should not be more than 1 hour. ① Preparation before configuration is the same as above.

② Weigh the A and B components of the required crystal glue in 3:1, mix well, and then drop it on the sign.

③ Gel solid: coated sign in the oven at 60 ℃ about 1.5 hours of heating can be; or placed at room temperature about 13 hours of self-drying. ① Configuration before the required PU crystal glue A and B two components to 100:100 weighed well, ready as above.

② A and B components of the required crystal adhesive to 1:1 weighed, stirred well, you can drop on the sign.

③ But hand-drop PU is slower, the environmental humidity requirements are higher, the relative humidity should be between 40 ~ 60, in order not to cause late blistering. It is recommended that the PU crystal glue using a glue dripping machine, see the method of glue dripping machine instructions.
