**QMS-995 High-Performance Structural Sealant**
The QMS-995 is a premium, single-component, neutral ketoxime-cured structural sealant designed to meet the rigorous demands of modern architectural applications. With medium modulus and exceptional durability, it is engineered for seamless integration of glass and metal components, creating strong, unified assemblies. Its outstanding UV, acid, and alkali resistance ensures long-term reliability, even in challenging environments. Ideal for fully hidden or semi-hidden frame curtain wall designs, the QMS-995 delivers superior structural sealing performance.
### **Key Features:**
- **Neutral Ketoxime Cure:** Non-corrosive and compatible with sensitive substrates.
- **Structural Integration:** Enables glass-to-metal bonding for unified assemblies, meeting advanced design requirements for curtain walls.
- **Exceptional Durability:** Resists UV exposure, acids, and alkalis, ensuring long-lasting performance.
- **Weatherproofing Excellence:** Provides robust sealing for harsh environmental conditions.
### **Applicable Materials:**
The QMS-995 is suitable for assembly and sealing of:
- Glass
- Ceramics and pottery products
- Fiberglass materials
- Galvanized metal surfaces
- Most plastic panels
- Non-oily wood
- Anodized or painted aluminum profiles
### **Use Restrictions:**
- **Temperature Sensitivity:** Not suitable for applications where the substrate's surface temperature exceeds 50°C.
- **Curing Environment:** Requires air exposure for proper curing; not applicable in fully enclosed or air-isolated environments.
### **Shelf Life:**
The QMS-995 maintains optimal performance for up to **12 months** when stored under recommended conditions.
With its advanced structural bonding capabilities and outstanding resistance to environmental stressors, the QMS-995 is the ideal solution for modern curtain wall designs and high-performance architectural applications.
