Room temperature vulcanized silicone rubber as an adhesive

Room temperature vulcanized silicone rubber is what, if you can not go to understand the words, small make up do not dare to say that is special understanding, a few days ago there is a customer asked about this topic, just go to browse the data.

So let's talk about one topic today: what is the value of RTV silicone rubber as an adhesive?

RTV (RTV) is a new type of silicone rubber introduced in the 1960s. The most prominent feature of RTV is that it can be cured on the spot without heating and pressure at room temperature. It is very convenient to use.

At present, room temperature vulcanized silicone rubber has been widely used as adhesive.

Silicone rubber adhesive the most adhesive is an adhesive made of silicone rubber.

RTV silicone rubber is called liquid silicone rubber because of its low molecular weight.

Its physical form is usually a flowing fluid or viscous paste with a viscosity between 100 and 1000 cm.

RTV silicone rubber with hydroxyl-terminated polysiloxane as base material, can be divided into single component and two components. One component RTV silicone rubber for the majority of base material has good adhesion, can be in 60-200 ℃ temperature range or less use for a long time, excellent electrical insulation and chemical stability, to all sorts of metal and nonmetal materials with good adhesion.

Mainly used for coating various electronic components and electrical equipment, including insulation, moisture-proof, shock-proof, etc., can also be used as sealing material and elastic adhesive.

The ratio of two components of rvulcanized silicone rubber is different.

However, due to poor bonding performance with the substrate, it is mainly used for insulation, packaging, joints, sealing, moisture proof, roll making and other materials in the fields of electronics and electrical appliances, automobiles, machinery and construction.

The strength of silicone rubber itself and the bonding strength of various materials are low, which limits the application range of silicone rubber.

At present, the research on strengthening modification of RTV silicone rubber adhesive mainly includes crosslinking agent, polysiloxane physical and chemical strengthening modification and adhesive surface modification to improve its bonding performance.
