Neutral RTV Silicone Heat Insulating Adhesive is a high-performance, room temperature vulcanizing silicone adhesive designed specifically for bonding and sealing aluminum panels and other metal substrates.
Product Introduction
Neutral RTV Silicone Heat Insulating Adhesive is a high-performance, room temperature vulcanizing silicone adhesive designed specifically for bonding and sealing aluminum panels and other metal substrates. With its neutral cure system, it avoids corrosion on sensitive materials such as aluminum, copper, and galvanized steel. This adhesive combines excellent thermal insulation, strong adhesion, and long-lasting durability, making it a reliable choice for industrial, construction, and electronic applications.
Key Features
Neutral Cure Formula: Non-corrosive, safe for aluminum and other metals.
Heat Insulation: Effectively reduces heat transfer, ensuring stable performance in high- and low-temperature environments.
Strong Adhesion: Provides excellent bonding strength on aluminum, glass, ceramics, and plastics.
Weather Resistance: Outstanding resistance to UV, ozone, and moisture for both indoor and outdoor use.
Flexibility: Remains elastic after curing, accommodating thermal expansion and vibration.
Easy Application: Single-component, ready-to-use adhesive that cures at room temperature.
