Room-temperature curing

Room-temperature curing, also known as condensation curing, is the process during which a one- or two-component silicone cures when exposed to room temperature and moisture.

These silicones are classified into alkoxides, acetoxides or oximes.

RTV silicones, i.e. silicones that undergo the curing process at room temperature such as ABCHIMIE R76, are used in a wide range of applications, mainly in sealing against moisture and environmental contaminants (see potting) or as anti-vibration systems and adhesives.

ABchimie offers a wide range of 1- and 2-component adhesives and sealants, many of which are used in the electronics industry during the assembly of sensitive electrical and electronic components.

 

Main features of silicones:

 

 

Properties RTV silicones Epoxy Urethanes
Range T°C -50°C/+200°C -50°C/+150°C -30°C/+120°C
Heat resistance excellent low low
Flame retardant excellent void void
UV resistance excellent low low
Ozone resistance excellent low low

 

These materials are used in a variety of methods ranging from manual dispensing to automatic dispensing units and are found in different packaging: in tubes, in cartridges, in drums.

The mixing of two-component silicones can be carried out using either manual processes or dosing units, depending on the production volume and the desired properties of the post-mixed material.
