Acid And Neutral Silicone Sealant Production Line | JCT Machinery

May 12, 2025
Market positioning and terminal applications
Target marketRecommended typeReason
Home decoration / ordinary door and window adhesive Acid silicone sealantLow cost, strong adhesion, suitable for low-end mass market
Building curtain wall / stone / metalNeutral alcohol silicone sealantNo corrosion to glass and metal, good weather resistance, suitable for mid-to-high-end projects
Electronics / home appliances / automotive adhesive
Neutral ketoxime silicone sealantLow odor, low volatility, no corrosion, suitable for precision industrial adhesive
OEM exportNeutral silicoen sealant

Overseas requirements for environmental protection and low corrosion, acid silicone sealant exports are limited

**You can first confirm whether the future product will be sold to the building materials market or the higher-end industrial market? If it is for the real estate or decoration market, the investment in acid silicone sealant is smaller, but if you plan to export or do high-end engineering projects, neutral silicone sealant is more valuable.

Neutral silicone sealant production line is more likely to require an oven, while acid silicone sealant production line do not.


Why neutral silicone sealant production line need oven?
  • Q
    1. High requirements for raw material pretreatment
    • Neutral silicone sealant is very sensitive to moisture (especially alcohol-type and ketoxime-type cross-linking systems).
    • Common fillers such as white carbon black, calcium powder, aluminum hydroxide, etc. contain trace amounts of adsorbed water and need to be pre-dried.
    • Prevent the colloid from premature cross-linking, foaming or odor during mixing or storage.
  • Q
    2. Some customers choose formulas containing high-volatile / high-viscosity additives
    • The formulation process may require preheating of raw materials to improve fluidity or promote dispersion.
    • Use an oven to treat the raw materials.
