5L Double Planetary Mixer for Silicone & Glass Adhesive: Ideal for Chemical Industry

In the electronics and construction industries, the quality of silicone and glass adhesive directly determines product reliability—whether it is the sealing of electronic components or the bonding of architectural glass, uniform dispersion of raw materials and bubble-free mixing are core requirements. However, the high viscosity of silicone and the strict compatibility requirements of glass adhesive pose great challenges to mixing equipment. Targeting these pain points, our 5L Double Planetary Mixer provides a professional, efficient and stable mixing solution for small-batch production and R&D scenarios.
The core competitiveness of the equipment lies in its customized double planetary mixing system, which is tailor-made for silicone and glass adhesive. The dual mixing paddles rotate at high speed around their own axes (rotation speed 0-850rpm) while revolving along the inner wall of the 5L container (revolution speed 0-120rpm). This dual-motion trajectory generates strong shearing, kneading and folding forces, which can fully disperse fillers such as fumed silica in silicone and eliminate agglomerates, and ensure uniform blending of resin and curing agent in glass adhesive. The mixing uniformity error is controlled within ±0.8%, far exceeding the industry average, and effectively avoiding problems such as weak bonding and poor sealing caused by uneven mixing.

The 5L effective volume design is perfectly matched to the small-batch production needs of the electronics and construction industries—whether it is the trial production of new silicone sealants for electronic modules or the small-batch preparation of high-performance glass adhesive for architectural curtain walls, it can meet the demand. The equipment is equipped with a double-layer vacuum jacketed container, which can achieve precise temperature control from -10℃ to 160℃ with a temperature control accuracy of ±0.3℃. This ensures that heat-sensitive components in silicone will not be damaged by high temperature, and the reaction temperature of glass adhesive during mixing is stable. The built-in high-efficiency vacuum system can reach a vacuum degree of -0.099MPa, quickly extracting micro-bubbles generated during mixing, ensuring that the cured silicone/glass adhesive has no voids and strong bonding strength.
Operation and safety are fully optimized for industrial scenarios. The equipment adopts a 7-inch color touch screen control system, which can store 80 sets of mixing programs for different types of silicone and glass adhesive. Operators only need one key to call the corresponding program, which greatly reduces the difficulty of operation and avoids human errors. In terms of safety, it is equipped with multiple protection mechanisms: overload protection will automatically shut down the machine when the mixing load exceeds the standard; the interlock device of the container cover prevents misoperation during operation; the high-temperature and high-pressure alarm system responds in real time to ensure the safety of operators and equipment. The container adopts a quick-opening flange structure, and the inner wall is polished to Ra≤0.4μm, which is easy to clean and avoids cross-contamination between different adhesives, complying with industrial production standards.
In terms of durability and after-sales, the equipment is built to withstand harsh industrial environments. The mixing paddles are made of 304 stainless steel with wear-resistant coating, which can resist the abrasion of abrasive fillers in silicone and glass adhesive, and the service life is increased by 50% compared with ordinary mixers. The machine body is made of thickened Q235 steel, and the bottom is equipped with shock-absorbing rubber pads, so the noise during operation is lower than 70dB, creating a quiet workshop environment. We provide global pre-sales technical consultation, on-site installation and commissioning, and 24-hour after-sales maintenance services. According to the special formulas of silicone and glass adhesive of different customers, we can customize paddle shapes (such as sigma paddle, butterfly paddle) and vacuum configurations to achieve precise matching of equipment and production processes.
As a professional mixing equipment for silicone and glass adhesive in the electronics and construction industries, this 5L Double Planetary Mixer not only solves the traditional mixing pain points of uneven dispersion and difficult bubble removal, but also improves production efficiency and product qualification rate for enterprises through intelligent control and stable performance. Whether it is a R&D laboratory developing new adhesives or a small-batch production workshop, it is an indispensable core equipment to enhance competitiveness.
