Bubble is the problem of agent B, change to another curing agent! Convenient, if you don't want to change, vacuum, or heat curing. There are bubbles because the solvent in the glue volatilizes, the crystal drops solidify too fast or the viscosity is too high, which leads to bubbles escaping.
2. The crystal drops are not dry, but show stickiness, moist feeling and blisters after curing.
When the weather is good, the glue drops normally; In low temperature and humid weather, the glue will solidify, but it is sticky, moist and blistered, which is mainly caused by the very serious water content of the glue itself. Only by overcoming the humidity in the workshop can we really solve the problem. Changing glue is not the cause of the problem. The glue with the ratio of 3: 1 has better moisture-proof performance.
3. When crystal glue falls, the glue is dry, and there are no fingerprints when you press it with your fingers. But once you cover the protective film and tear off the glue surface, there will be lines and stains, and your fingers will not disappear.
The hardness of solidified crystal drops is high, which can not cover the particle stains; There is only one reason: the temperature resistance of epoxy crystal drops is not very good, and it will soften when it meets high temperature. If they are exposed to high temperature for a long time, they will soften and deform. It may be that your product is covered with protective film and then exposed to high temperature.
4. Is the curing agent A and resin B of crystal glue products that I used to make photo albums toxic?
Crystal drops contain formaldehyde, which is slightly toxic. Pay special attention not to get into eyes.
5. Different proportions of crystal drops will produce different effects.
2.5: 1, which may cause the product surface to be dry.
Glue can also be 3: 1, 2: 1, or even 1: 1, and the product can be completely dried.
