Product Description

**HC-995 High-Performance Silicone Structural Sealant**  

**Product Overview**  
The HC-995 is a premium, single-component neutral ketoxime-cured silicone structural sealant designed to meet the rigorous demands of modern architectural applications. With medium modulus and exceptional durability, it offers superior UV, acid, and alkali resistance. This high-performance sealant seamlessly bonds glass and metal components into unified assemblies, making it ideal for fully hidden or semi-hidden frame curtain wall designs.  

### **Key Features**  
- **Neutral Ketoxime Cure:** Non-corrosive to sensitive substrates, ensuring safe and effective application.  
- **Structural Integration:** Creates a durable bond between glass and metal components, supporting advanced architectural designs.  
- **Exceptional Durability:** Resistant to UV rays, acids, and alkalis for long-lasting performance.  
- **Weatherproof Excellence:** Maintains structural integrity and sealing performance in challenging environments.  

### **Applicable Materials**  
The HC-995 is compatible with:  
- Glass  
- Ceramics and pottery  
- Fiberglass  
- Galvanized metal surfaces  
- Most plastic panels  
- Non-oily wood  
- Anodized or painted aluminum profiles  

### **Usage Restrictions**  
To ensure optimal performance, avoid the following scenarios:  
- **High Temperatures:** Not suitable for substrates with surface temperatures exceeding 50°C during application.  
- **Curing Environment:** Requires air exposure for proper curing; unsuitable for fully enclosed or air-isolated environments.  

### **Shelf Life**  
The HC-995 retains optimal performance for up to **12 months** when stored under recommended conditions.  

**Why Choose HC-995?**

APPLICATION
Apply to clean, dry and grease-free surfaces. Cut the nozzle at 45°angle to the desired shape and size. For better appearance, cover outside of joint areas with masking tape before application.  
 Tool immediately after sealant application and remove masking tape before sealant skins.

Caution
Uncured silicone can irritate eyes and skin. If contact is made with eyes, flush with water for 15 minutes and seek medical advice. Use in well ventilated area and keep out of reach for children.
LIMITATIONS
1.Unsuitable for curtain wall structural applicatio
2.Do not use for below ground.
3.Do not use when substrate temperature is above 50ºC or surfaces that are wet, oily, greasy, dusty or dirty.
4.The surfaces coated with paint are unsuitable for sealant.
5.Do not clean or treat the sealant with materials, solvents or cleaning agents that may affect or discolor the sealant, particularly during sealant cure.
