NEOSEAL, The Professional Choice for Industrial Sealing Putty

2026/03/20

In electrical installations, building construction, and industrial equipment assembly, hole sealing, conduit penetration sealing, and protection against water and dust are critical steps that should never be overlooked. If openings or penetrations are not properly sealed, it may lead to:
• Moisture entering equipment
• Dust and contaminants infiltrating systems
• Electrical short circuits or equipment failure
• Reduced energy efficiency in buildings
Among these solutions, NEOSEAL® Putty, developed by the Japan "Nitto Chemical Industry Co., Ltd.", is the one that has been widely used in these fields.

⭕ What is Moldable Sealing Putty?
Industrial moldable sealing putty is a type of non-hardening sealing material with a clay-like consistency. It can be easily shaped by hand and used to fill openings, gaps, or penetrations.  A high-quality sealing putty should have the following characteristics:
• It does not harden or crack over time
• High moldability and flexibility
• Good adhesion to a wide range of material surfaces
• Effective resistance to water and dust intrusion
Compared with traditional sealants such as silicone or adhesive compounds, its biggest advantage is that it does not require curing to form an effective seal.

⭕ In addition to the advantages mentioned above, the NEOSEAL® series also offers a variety of specialized property options to meet the application requirements of different environments and industries.
