Neutral Silicone Sealant Production Line

Neutral silicone sealants are a mainstream material for building doors and windows, glass curtain walls, interior decoration, and electronic packaging. Their production has stringent requirements for the process environment. Because neutral adhesives (especially alcohol-based and ketoxime-based ones) are extremely prone to moisture absorption and curing during synthesis and storage, the precision of the proportions of key additives such as crosslinking agents and coupling agents directly determines the non-yellowing properties, adhesion, and curing speed of the adhesive.

The entire neutral silicone sealant production line adopts a modular, assembly line design and can be customized according to the customer's production capacity requirements as a single-machine intermittent production line for heavy-duty machines/planetary machines or a fully automated continuous base material-finished product production line.

Main Equipment and Process Flow of Neutral Silicone Sealant Production Line

1. [Base material preparation system]: Base material dispersion mixer: Mixes some raw materials.

2. [High-efficiency dehydration system]: High-temperature, high-vacuum deep dehydration, reducing moisture content to <0.05%.
