**HC-883 High-Performance Acidic-Curing Silicone Glass Sealant**
**Product Overview**
The HC-883 is a premium, single-component silicone adhesive featuring acidic curing technology, specifically engineered for demanding glass and aluminum assembly projects. With exceptional durability and versatility, it is the ideal solution for large glass installations, advanced glass projects, lighting ceilings, and aluminum alloy glass doors and windows. Perfect for sealing and assembling large windows, it ensures reliable and long-lasting performance in both residential and commercial applications.
### **Key Features**
- **Acidic Cure Technology:** Provides fast curing and strong adhesion for advanced glass and aluminum applications.
- **Versatile Usage:** Tailored for large-scale installations, including glass facades, lighting ceilings, and large window assemblies.
- **Durability:** Delivers long-lasting, weather-resistant seals that withstand environmental stress.
### **Applicable Materials**
The HC-883 is compatible with:
- Glass
- Ceramics
- Fiberglass
- Non-oily wood
- Aluminum profiles
- Painted material surfaces
**Note:** For aluminum profiles with powder coating, thoroughly clean the surface with a solvent to remove any coating wax before applying for optimal adhesion.
### **Usage Restrictions**
To ensure optimal results, avoid using HC-883 in the following scenarios:
- **Incompatible Materials:** Not suitable for concrete, cement, structural components, or substrates containing zinc, brass, copper, or lead.
- **Curing Limitations:** Avoid continuous water immersion or air-isolated environments before curing.
- **Special Applications:** Not recommended for surfaces requiring painting or for architectural-grade engineering sealants.
### **Shelf Life**
The HC-883 retains optimal performance for up to **12 months** when stored under appropriate conditions.
Combining high-strength adhesion with professional-grade reliability, HC-883 is the ideal choice for large-scale glass installations and advanced construction sealing projects.
