The Differences Between Silicone Sealant and Nail-Free Glue

Silicone sealant

Silicone sealant is a high-performance adhesive material mainly composed of high-quality silicone resin, pigments and additives. It cures by reacting with moisture in the air at room temperature to form a flexible and dense rubber film, which is mainly used for sealing, waterproofing and auxiliary bonding. It is divided into acid and neutral types, among which neutral silicone sealant is more widely used due to its non-corrosive characteristics.

Nail-free glue

Nail-free glue, also known as liquid nail, is a high-strength multi-functional structural adhesive, mainly composed of MS polymer (modified silane polymer) or polyurethane. Its core function is to replace traditional fasteners such as nails and screws, realizing firm bonding between various materials without drilling or nailing, and forming a solid adhesive layer after curing.

Silicone sealant

The core advantage of silicone sealant lies in its excellent weather resistance, waterproof and mold-proof performance. After curing, it has good flexibility and displacement resistance, can adapt to thermal expansion and contraction of materials, and is not easy to yellow, powder or crack under long-term exposure to sunlight and harsh environments. It has low shrinkage during curing and excellent adhesion to glass, ceramics, metal and other substrates, but its bonding strength is relatively weak and it is not suitable for load-bearing scenarios.

Nail-free glue

Nail-free glue is characterized by super strong bonding strength. After complete curing, its bonding force can even exceed that of iron nails, and it has good compatibility with most materials such as wood, plastic, stone and metal. It is easy to construct, requires only a small amount of coating, and will not damage the base material. However, its weather resistance and waterproof performance are weaker than those of silicone sealant, and it is easy to degum in long-term humid or outdoor environments. The curing time is relatively long, usually 24-48 hours to reach the best bonding strength.

Silicone sealant

Silicone sealant is mainly used for sealing and waterproofing scenarios. It is widely used in indoor and outdoor decoration, such as sealing gaps between doors and windows, bonding and sealing of kitchen and bathroom sanitary ware, glass assembly, pipeline engineering, and sealing of expansion joints of building structures. It is especially suitable for humid environments such as kitchens and bathrooms because of its mold-proof and waterproof properties. It can also be used in industrial fields such as automobiles and ships.

Nail-free glue

Nail-free glue is mainly used for bonding and fixing scenarios, which is very suitable for occasions where drilling is not allowed or not convenient, such as rental houses and finished decoration. It is widely used in fixing wall hangers, decorative panels, skirting lines, bathroom mirrors, shelves and other items. It can also be used for bonding between wood, metal and other materials in furniture production, which is firm and does not loosen. High-strength nail-free glue can also be used for fixing heavy objects such as large metal hangers and stone materials.
