Drip glue is also called epoxy resin crystal drip glue, crystal drip glue is composed of high purity epoxy resin, curing agent and other substances. The cured product has the characteristics of water resistance, chemical corrosion resistance and crystal clear. Its characteristics protect the surface of the process products and add luster.






In the process of production and use of dropping glue, foam is easily generated in the dropping glue due to the air involved in stirring and the change of temperature, which not only limits the production speed of the dropping glue, but also causes the appearance of the dropping glue to be unattractive. At this time, you need to use a drip defoamer.






The drop glue defoamer is mainly developed for the drop glue, mainly according to the material made of the drop glue, and the reason for foaming in the work, the purpose is to make the drop glue in the transportation, or agitation to play the role of defoaming and foaming.






Why do drops foam during production or use? What causes the blistering?


1. When making the drops, due to the uneven speed of manual mixing, a large amount of air is involved, and the gas is difficult to escape in the drops, resulting in the generation of foam;


2. The drip solidification process is an exothermic reaction, at this time the air inside will be heated and expanded, but at this time the drip glue has been thick, the air has not emerged from the surface, and can only gather inside to form bubble groups;


3. Affected by the external temperature, it is easy to produce a large number of fine foams when the glue is heated and expanded at high temperature;


4. The inside of the glue contains impurities, which are not removed in time, and foam is generated during solidification.






What are the effects of epoxy resin foam if it is not eliminated in time?


1. A large number of bubbles in the production of drops will affect the decorative effect of drops, resulting in the product is not beautiful enough;


2. The generation of foam will also affect the protective effect of the drop glue, reducing the water resistance and corrosion resistance of the drop glue;


3. In the production and use of drip glue, a large amount of foam will reduce the production progress of drip glue, slow down the production process, and lead to the decline of drip glue production efficiency;


4. If the foam in the drops is not eliminated in time, it will increase the difficulty of defoaming after the drops solidify, resulting in unnecessary cost increase.






What are the advantages of using a drip defoamer in the face of drip foam?


1. The drip defoamer is specially tailored for the drip foam problem, with fast defoaming speed and long foam suppression time;


2. Added to the drops will not affect the beauty of the drops, will not affect the protection and decorative effects of the drops, and will not change the appearance and color of the drops;


3. High temperature, acid and alkali resistance. In these environments, it can also defoaming and suppressing bubbles, and its chemical properties are very stable.
