Product Description

**HC-885 Premium Neutral Ketoxime Sealant for Aluminum Alloy Doors and Windows**  

**Product Overview**  
The HC-885 is a high-quality, single-component neutral ketoxime sealant specifically engineered for aluminum alloy doors and windows. With medium modulus and outstanding weather resistance, it offers durable, corrosion-free bonding and sealing for a wide range of construction materials. Its advanced formulation ensures long-term protection, making it the perfect choice for high-performance architectural applications.  

### **Key Features**  
- **Neutral Ketoxime Cure:** Non-corrosive to substrates, ensuring safe application on sensitive materials.  
- **Medium Modulus:** Provides a balanced combination of flexibility and durability for long-lasting performance.  
- **Weather-Resistant:** Exceptional resistance to harsh environmental conditions, offering reliable sealing and protection.  
- **Versatile Application:** Suitable for a variety of materials commonly used in construction and assembly.  

### **Applicable Materials**  
The HC-885 is ideal for the combined assembly and sealing of:  
- Glass  
- Ceramics and pottery  
- Fiberglass  
- Galvanized metal surfaces  
- Most plastic panels  
- Non-oily wood  
- Anodized or painted aluminum profiles  

**Important Note:** While HC-885 is suitable for many materials, it is not recommended for use on mirrors or coated glass without thorough compatibility testing.  

### **Usage Restrictions**  
- **Temperature Sensitivity:** Not suitable for substrates with surface temperatures exceeding 50°C.  
- **Curing Environment:** Requires air exposure for curing; avoid application in fully air-isolated environments.  

### **Shelf Life**  
The HC-885 maintains peak performance for up to **12 months** when stored under recommended conditions.  

Combining advanced neutral cure technology with superior weather resistance, HC-885 is the trusted solution for sealing and bonding aluminum alloy doors, windows, and other architectural materials with precision and durability.
