The seam an agent in recent years new up an industry, replaced the previous gap filling agent, the more common on the market is A two-component AB, A component is mainly epoxy, silicon and auxiliary gas, B component mainly firming agent, silicon, pigments and additives, the seam an agent is the most important A performance AB mixture to prevent sagging, achieve the result that on the wall does not flow, we now have three kinds of additives can solve the problem existed in the seam an agent industry on the market:
Epoxy defoaming agent 5800: Organosilicone defoaming agent, mainly used in epoxy system, defoaming fast, can quickly remove the rice bubble.Bubbles in epoxy components will lead to empty bubble phenomenon, uneven glue production and other problems. It is difficult to remove the bubble of rice grain by vacuum. Adding defoamer 5800 can effectively eliminate the bubble.
Epoxy thickeners 605A and 606A: The viscosity of the epoxy is related to the air temperature, and it is usually compared with ene in summer, which will lead to the problems of glue leakage and uneven glue production, etc. The combination of 605A and 606A with aerated silicon can effectively and controllable increase the epoxy viscosity, so that the viscosity and curing agent components reach the same, the glue production is more uniform, and prevent glue leakage phenomenon.
Thixotropic stop agent 607 and 608: After mixing AB components, anti-flow performance is required to form the contact variation to achieve the effect of no flow on the wall. The combination of thixotropic stop agent 607 and 608 with gas silicon can effectively form a thixotropic network with excellent anti-flow performance.
