​​1. Main Types of Sealant Production Lines​​

​​Silicone Sealants​​

• ​​Acidic/Neutral Silicone Sealants​​: The production line adjusts pH (acidic or neutral curing) and formulations to produce products like architectural curtain wall sealants and window/door sealants. Acidic sealants cure quickly but may corrode metals, while neutral sealants are non-corrosive and suitable for substrates like glass and ceramics.
• ​​Photovoltaic Silicone Sealants​​: Specifically designed for solar panel encapsulation, offering UV and high-temperature resistance (e.g., Huitian New Materials' 180,000-ton annual production line).
• ​​Fire-Resistant Sealants​​: Single-component, medium-to-high modulus design with a fire resistance rating of up to 3 hours, used in firestop systems and fire-resistant windows.

​​Polyurethane Sealants​​
The production line utilizes high-shear dispersers and planetary mixers for high-viscosity material blending. Products exhibit high elasticity and weather resistance, making them suitable for automotive windshield bonding (e.g., 3M™ Polyurethane Sealant 590) and construction joint sealing.

​​Silane-Modified Polyether (SMP) Sealants​​
Highly resistant to UV and chemical corrosion, used for outdoor industrial equipment sealing (e.g., 3M™ 740 UV Sealant).

​​Anaerobic Sealants​​
Examples include Loctite 515 and 518 thread sealants, suitable for rigid flanges (gap ≤0.25mm), with fast curing for sealing pumps and gearboxes.

​​Specialty Functional Sealants​​

• ​​Electronic Potting Compounds​​: Thermally conductive potting compounds for lithium battery cells (e.g., Huitian New Materials' products).
• ​​Butyl Sealant Tapes​​: Used for waterproofing construction joints (e.g., 3M™ Weatherban™).

​​🏗️ 2. Core Application Areas​​
​​1. Construction & Curtain Wall Engineering​​

• ​​Glass/Stone Curtain Walls​​: Silicone weatherproof sealants (movement capability ±20%~50%) ensure joint airtightness (e.g., Lingzhi LL806 weatherproof sealant).
• ​​Door/Window Installation​​: Neutral silicone sealants for frame sealing, offering aging resistance and non-corrosiveness.
• ​​Firestopping​​: Fire-resistant sealants for sealing pipe penetrations and duct gaps.

​​2. New Energy Sector​​

• ​​Photovoltaics​​: Photovoltaic silicone sealants encapsulate solar panels, requiring high weather resistance (Huitian New Materials holds 45% market share).
• ​​New Energy Vehicles​​: High-thermal-conductivity potting compounds for battery packs; polyurethane sealants for windshield bonding (meeting FMVSS 212 crash standards).

​​3. Industrial Manufacturing & Maintenance​​

• ​​Automotive/Machinery​​: Anaerobic sealants for engine flange sealing (Loctite 518); silicone sealants for oil pan repairs (Loctite 5699).
• ​​Electronics​​: Electronic adhesives for consumer electronics (e.g., Huitian New Materials supplies Xiaomi and VIVO).
• ​​Pipeline Engineering​​: Thread sealants replace PTFE tape, withstanding high-pressure vibrations (Loctite 567/577).

​​4. Other Fields​​

• ​​Aerospace​​: High-performance sealants for corrosion-resistant sealing of critical components.
• ​​Green Packaging​​: Water-based sealants meet environmental requirements.
