Basic Formula of Silicone Sealant
Ingredients | Functions |
107 glue (hydroxyl-terminated polydimethylsiloxane) | Base polymer of silicone sealant, providing elasticity and film-forming properties |
Filler | Increase colloid strength and improve viscosity |
Crosslinking agent | Participate in the curing reaction to form a siloxane network structure |
Catalyst | Accelerate the curing reaction |
Thickener | Increase the adhesion of the colloid to the substrate |
Additives | Adjust construction performance and enhance weather resistance |
Plasticizer | Improve fluidity and adjust hardness |
1. Efficient Mixing: Use a powerful dispersing mixer (triple shaft mixer) or double planetary mixer to ensure uniform dispersion and improve product stability.
2. Vacuum Degassing: Remove bubbles to ensure the sealing performance of silicone sealant.
3. Automated Production: From material transportation, mixing, filling to packaging, improve production efficiency and reduce labor costs.
4. Precise Control: PLC automatically controls temperature, pressure, and mixing time to ensure product quality consistency.
1. Powerful Dispersing Mixer
Used to mix 107 glue, white carbon black, thickener, etc. to improve the uniformity of dispersion and avoid agglomeration.
Can be used with a vacuum system to prevent the generation of bubbles.
2. Double Planetary Mixer
Used for uniform mixing and dispersion of high-viscosity silicone sealant (>100,000cps).
Double planetary mixing + scraping wall design is used to ensure that the materials are fully mixed.
3. Vacuum Degassing System
Remove air from silicone sealant to improve product density and quality.
Prevent curing agent from contacting with air and extend storage time.
4. Filling Machine
Fill silicone sealant into plastic hoses, hard tubes or soft packaging.
Semi-automatic Filling Machine: Suitable for small and medium-sized production needs.
Fully automatic Filling Machine: Integrated with automatic weighing, tail sealing, batch number printing and other functions.
