In some healthcare, wellness, physical therapy, and massage devices, stones such as bian stone, quartzite, and energy stones are often used as massage mediums that come into contact with the human skin. To securely fix and bond these stones to plastic or metal casings, a reliable adhesive is required. Hengchang Silicone’s HC-836W silicone sealant is an excellent choice for this purpose.
Instant adhesives like 502, while meeting the requirements in terms of bonding strength, may not be ideal in certain scenarios. Both the stone and the plastic or metal casings are rigid, and some dimensional tolerances are inevitable during the manufacturing process. This means that after assembly, there may be significant gaps between the stone and the casing. Instant adhesives like 502 release a substantial amount of volatiles during the curing process, leading to noticeable shrinkage in volume. As a result, they struggle to fully fill the gaps between the stone and the casing, posing a risk of detachment.
In contrast, HC-836W, with its silicone-based formulation, releases minimal volatiles during curing and experiences almost no volume shrinkage after solidification. It effectively fills the gaps between the stone and the casing, ensuring maximum contact area and a strong, reliable bond.
Additionally, stones such as bian stone, quartzite, and energy stones used in physical therapy devices often generate heat during operation. Many common adhesives have limited temperature resistance. However, HC-836W silicone sealant offers a temperature resistance range of -40°C to 200°C, allowing for long-term stable use within this range without issues such as melting, brittleness, or detachment.
Moreover, HC-836W silicone sealant boasts excellent waterproofing, corrosion resistance, weather resistance, and aging resistance. After curing, it forms a flexible elastomer that not only adheres firmly to common industrial materials like plastic, metal, glass, stone, and ceramics but also provides protective benefits such as waterproofing, corrosion resistance, and shock absorption for the bonded surfaces.
