Building for the future

By cooperating with architects, engineers, building designers, contractors and material manufacturers, we are committed to developing a range of chemicals, formulations and materials. These technologies improve the performance, durability, aesthetics and sustainability of the entire building system. From roads to roofs, from residences to skyscrapers, we provide solutions that can reduce waste, improve efficiency, and ultimately achieve the development goal, which is not only visually attractive and powerful structure and function, but also has excellent environmental protection characteristics.

The long-proven silicone technology covers widely used sealants and epoxy products, and achieves durability and high-performance design in structural assembly, weather resistance applications, door and window glass, insulating glass, and infrastructure applications.

In the application, we will come into contact with concepts such as structural adhesives, double glass adhesives, weather-resistant adhesives, and fire-resistant adhesives. What are the roles of these different types of sealants? How are they classified?

This article will introduce the classification of building silicone sealants from the perspective of usage.

Construction silicone sealants can be roughly divided into the following five categories according to their uses: structural silicone sealants, weatherproof silicone sealants, general purpose silicone sealants, double glass silicone sealants for insulating glass, and special-purpose silicone sealants .

1. Structural Silicone Sealant

Uses: Mainly used for the structural bonding of glass and aluminum sub-frames (see Figure 1), and also used for secondary sealing of double glass in hidden frame curtain walls.

Features: bearing load, gravity load, high requirements for strength, aging resistance, and certain requirements for elasticity.

2. Weather-resistant Silicone Sealant

Uses: The sealing effect of the curtain wall joints (see Figure 1) to ensure the air-tightness and water-tightness of the curtain wall.

Features: Need to withstand large changes in the width of the joint, high elasticity (displacement capacity), high aging resistance, no strength, high modulus, low modulus.


3. General Purpose Silicone Sealant

Purpose: Sealing of door and window joints, external wall filling and other locations (see Figure 2).

Features: Withstand changes in the width of the joints, and have certain displacement requirements, but no strength is required.


4. Two-layer Silicone Sealant for Insulating Glass

Purpose: The double glass is sealed in two ways to ensure the stable structure of the glass (see Figure 3).

Features: High modulus, not too soft, some have structural requirements.


5. Special purpose silicone sealant

Uses: used for joint sealing with special requirements, such as fire proof, mildew proof (see Figure 5), etc.

Features: Need to have a certain special performance (such as mildew, fire, etc.).
