Objective
New developments of silicone sealants curable by ultraviolet radiation, and also new photoinitiators modified by sylanization have been obtained. Actually, there are very few silicones curable by ultraviolet radiation in the market, and their applications do not include the construction field.
The photopolymerization technique is very important to obtain the desired properties. The selection of the lamps and the photoinitiator is crucial for the development of the new silicone sealants. According to the kind of silicone, transparent or pigmented silicones, the lamps and the photoinitiators most suitable have been selected.
The obtained properties vary according to the kind of silicones. In general the obtained cure depth is greater for the transparent silicones than for the pigmented ones. The cure depth varies according to the used lamp, the selected photoinitiator and the acrylated silicone content.
According to the raw materials selected for the formulation the characteristics of the silicone sealants can result for different application fields. The applications of these new silicone sealants can be diverse. The aim of the present project has been to obtain silicone sealants curable by UV radiation for the construction field (windows manufacturing,...). The industrial validation shows that these silicon sealants can be used in a window application with simple barrier and even in a window application with double barrier, but other applications could be studied.
This new silicones offer a wide range of advantages:
- Short drying cycles, which allow to manipulate the pieces after a short period of time without any problem
- A single component systems, without any volatile solvent content.
