Definitions
- the field of the invention is that of one-component silicone sealants, stable on storage in the absence of moisture, non-yellowing, endowed with efficient biocidal (bactericidal / fungicidal) properties and crosslinking in adherent elastomers on various supports, at temperature ambient (for example 5 to 35 ° C) and in the presence of water (for example ambient humidity).
- Such sealants based on silicone elastomers are used in many applications, in particular in the building industry, as a means of sealing, jointing and / or assembly among others.
- the rheological properties of these monocomponent silicone sealants (pasty form) are the subject of much attention in these applications. The same applies to their resistance to weathering and heat, their flexibility at low temperatures, their ease of implementation and their rapid crosslinking / hardening in situ, in contact with air humidity.
- silicone sealants are used in humid and hot environments such as bathrooms or kitchens. These conditions are conducive to the proliferation of microorganisms such as bacteria, fungi or other molds on the surface of the silicone sealant. Such a microbiological invasion is likely to alter the appearance of the surface of the silicone seal: color, dirt and black or pink spots.
- French patent application FR-A-2 421 195 describes a polyorganosiloxane composition which can be vulcanized into an elastomer in the presence of humidity at ambient temperature.
- This composition comprises a POS A carrying hydroxyl units functionalizable by oxime, acyl, amine, amide or alkoxy radicals, a crosslinker B carrying functionalization radicals, a fungicide C consisting of 2- (4-thiazolyl) benzimidazole and a surfactant D of the polysiloxane / polyoxyalkylene copolymer type (polyoxyethylene nonylphenyl ether).
- biocidal substance for example antifungal in the formulations of silicone sealants
