Silicon Sealant Sigma Mixer

Silicone sealants require precise blending of polymers, fillers, catalysts, and additives into a uniform, bubble-free, high-viscosity paste. The mixer’s intensive kneading action with sigma-shaped (Z-blade) blades rotating at different speeds in opposite directions handles thick, sticky compounds effectively, delivering consistent, lump-free results that standard mixers cannot achieve.

It is constructed from robust industrial metals including Mild Steel, SS 304, and SS 316. Surface finishes can be customized from a sleek matte texture to a high-gloss reflective mirror polish. Mild steel units typically receive a protective red oxide primer followed by a dual-layer epoxy paint finish. PTFE shaft seals ensure sanitary, food-grade compatible operation.

High-precision, counter-rotating ‘Z’-profile (Sigma) agitators move at varying speeds to create a tangential kneading effect. This continuously shifts material from one side of the trough to the other through stretching, folding, splitting, and re-blending, while intense shearing between the blades and trough walls reduces particle size and eliminates dead zones.

Tangential ‘Z’ blades (typically at a 3:2 speed ratio) are optimized for heavy-duty, high-viscosity formulations like silicone sealants, adhesives, and elastomeric compounds. Overlapping blades (running at identical speeds) suit lower-viscosity free-flowing materials. Ultra-tight clearance between blades and trough walls prevents product retention or sticking.

Models range from ASM-50 (approx. 50 L working / 80 L gross capacity, 5–7.5 HP) to ASM-3000 (approx. 3000 L working / 3800 L gross, 100–120 HP). Intermediate sizes include 75 L, 100 L, 150 L, 200 L, 400 L, 500 L, 750 L, 1000 L, 1500 L, and 2000 L, available in general and heavy-duty motor variants. Voltage can be adjusted to customer requirements.

Product can be emptied via manual hand-wheel tilting, automated hydraulic tilting, bottom-mounted drainage valves, or a lateral extrusion screw positioned alongside the vessel. These options efficiently handle viscous pastes according to production needs.

Yes. Custom temperature jackets allow precise internal heating or cooling. The trough is insulated with high-density mineral wool and protected by external metal cladding. Optional blade cooling arrangements further support temperature-sensitive processes.

Optional modules include vacuum integration for de-aeration (to remove air bubbles), controlled fluid spray systems, hydraulic lids, screw/extrusion systems, automatic valve discharge, and explosion-proof designs. These support processes such as moistening, plasticizing, degassing, and polymerization.

It is primarily used for silicone sealants in construction, glazing, automotive, and general bonding applications. It is also widely applied in the chemical, adhesive, rubber, pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, and cosmetic industries for high-viscosity products such as hot-melt adhesives, silicone rubber, putties, and similar materials.
