The difference between room temperature vulcanized silicone rubber and high temperature vulcanized silicone rubber is that it is based on polysiloxane with a small molecular weight, and can be vulcanized into an elastomer at room temperature or with a little heating under the action of a crosslinking agent and a catalyst.
RTV silicone rubber is composed of base rubber, crosslinking agent, catalyst, filler and so on. The main applications are:
1. Construction industry
Silicone structural adhesives are mainly used for structural or non-structural bonding between metal and glass of glass curtain walls. 2. It can directly connect the glass with the surface of the metal component to form a single assembly component, which meets the design requirements of the curtain wall with fully hidden or semi-hidden frames. 3. Structural bonding and sealing of insulating glass.
Neutral weather-resistant adhesive: 1. Suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging; 2. Metal, glass, aluminum, tiles, plexiglass, Joint sealing between coated glass; 3. Joint sealing on the surface of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. Primer is not required in most cases.
2. Electronic industry
It can be encapsulated, poured, impregnated, coated, bonded, etc., moisture-proof, dust-proof, arc-proof, corrosion-proof, shock-proof and impact-proof. Potting protection for electrical components. Adding thermal conductive filler, it can be used as heat dissipation adhesive for electrical appliances.
3. Photovoltaic industry
4. Electricity
It is mostly used for bonding and filling of glass bricks, glass ceramic bricks, and anti-corrosion alloy materials in chimneys and pipeline anti-corrosion lining systems of thermal power plants; bottom sealing of thermal power plant equipment and facilities with anti-corrosion systems.
5. Medical industry
Silicone rubber is non-toxic, odorless, and physiologically inert. It can be used as anti-noise earplugs and soft liners for denture bases. Used as a dental impression material. For facelifts and make-up.
6. Automobile aviation, etc.
Automotive window seals, electrical and electronic connectors, gaskets, reflector lights, exhaust pipes, and adhesive seals for instruments.
The use of form-in-place gaskets has grown rapidly. Wide operating temperature, good impact resistance, good compression set, good sealing, low cost and simple process.
