Definitions
- the invention relates to secondary aminosilanes and their use, in particular as adhesion promoters and crosslinkers, and as a structural component of silane-functional polymers; and curable compositions, in particular silane-crosslinking curable compositions, and their use, in particular as casting compounds, sealants, adhesives, coatings, coatings and paints.
- curable compositions in particular silane-crosslinking curable compositions, and their use, in particular as casting compounds, sealants, adhesives, coatings, coatings and paints.
- Amino-containing organoalkoxysilanes are used inter alia as adhesion promoters, as crosslinkers for curable compositions and as synthesis components of silane-functional polymers.
- Aminosilanes with primary amino groups (“primary aminosilanes") are the most widely used because of their ease of preparation, but they have some drawbacks in their use, and due to the relatively hydrophilic primary amino group, they tend to be unwanted for moisture absorption, which adversely affects the adhesion of moisture
- primary aminosilanes lead to high viscosities, complicate the processability of the silane-functional polymers and worsen the application properties and extensibility of the silane-functional polymers It may therefore be advantageous to use, instead of the primary aminosilanes, those having secondary amino groups (“secondary aminosilanes"
- Secondary aminosilanes are classically obtained by hydrosilylation of allylsilanes, described, for example, in US Pat. No. 6,197,912, or by nucleophilic substitution of chloro or bromoalkylsilanes with primary amines, or of alkyl or aryl halides with primary aminosilanes, described, for example, in US Pat. No. 3,676,478 or US Pat. US 6,197,912.
- the Michael adducts of primary aminosilanes have additional functional groups, such as cyano groups and especially ester groups.
- ester groups leads to silane-functional polyurethane polymers of relatively low viscosity.
- this has the disadvantage that the ester groups are reactive with primary or secondary amino groups and thereby form amides.
- Silane-curing curable compositions which are usually formulated with primary amines and aminosilanes as catalysts and adhesion promoters, this is undesirable because it can lead to the deactivation of the amines and increased crosslinking density and thus to higher brittleness of the cured polymer. Incompletely alkylated aminosilanes with ester groups are often also poorly storable because of creeping self-condensation to give polyamides. Presentation of the invention
- the object of the invention is therefore to provide new secondary aminosilanes which have advantageous properties in use as adhesion promoters and crosslinkers and as structural components of silane-functional polymers. So they should be produced in a simple process, be liquid at room temperature and have a low viscosity. In particular, they are to enable silane-functional polymers which have a low viscosity, a rapid curing and a good thermal resistance.
- secondary aminosilanes according to claim 1 solve this problem. They are usually liquid at room temperature and relatively low viscosity and still have a low volatility and little odor. They can be prepared from commercial primary amino silanes and special aldehydes containing a secondary or tertiary amino group in a simple process which does not require any elaborate work-up steps. Advantageous properties such as the rapid hydrolysis rate of the silane groups, the good compatibility in many curable compositions and the particularly good adhesion-promoting properties can presumably be attributed to the presence of the additional amino group derived from the aldehyde.
- Silane-crosslinkable curable compositions containing such silane-functional polymers are of comparatively low viscosity, cure quickly and completely upon contact with moisture, and surprisingly have excellent thermal stability which is substantially better than that of comparable prior art secondary aminosilanes manufactured systems.

- the aminosilanes of the formula (I) are novel compounds with surprising properties. They are usually liquid at room temperature and relatively low viscosity, which is a great advantage for many applications. Nevertheless, they have a low volatility and little odor, which is often not the case for low-viscosity amino compounds. Furthermore, they can be prepared from commercial primary aminosilanes and the described aldehydes ALD of the formula (IV) in a simple process which does not require any elaborate work-up steps.

They are usually liquid at room temperature and relatively low viscosity and have a low volatility and little smell on. In the absence of moisture, they are storage-stable. Upon contact with water, hydrolysis of both the imino groups and also the silane groups takes place. The imino groups react formally to primary amino groups during hydrolysis, releasing the corresponding aldehyde ALD. In the presence of amine-reactive groups, such as, for example, isocyanate groups, the primary amino groups continue to react, for example with the formation of urea groups. As a result, the hydrolysis of the imino groups proceeds rapidly and completely.

- the aspect (“aspect Zus.") was evaluated and the skin formation time ("HBZ") in the standard environment (23 ⁇ 1 ° C, 50 ⁇ 5% relative humidity) determined as a measure of the cure rate.
- HBZ skin formation time
- a few grams of the space temperature-warm composition in a layer thickness of about 2 mm were applied to cardboard and determined in standard climate, the time it took to lightly tapping the surface of the adhesive by means of a pipette of LDPE for the first time no residue on the The eyedropper remained behind.
- the second film was then each stored after curing in standard atmosphere for 7 days at 70 ° C and 100% relative humidity and then determined in the same way, the tensile strength, elongation at break and modulus at 0.5-5% elongation (values in the table was labeled "(70/100)") Curing in standard atmosphere for 7 days stored at 90 ° C and then determined in the same way, the tensile strength, elongation at break and modulus at 0.5-5% elongation (values in the table with "(90 ° C)"). From this film was finally judged the aspect ("aspect film 90 ° C").
- Comparative Examples 15, 17 and 18 all exhibited tack-free films, while Comparative Examples 20 and 21, each containing a silane-secondary polymer with the secondary aminosilane of the prior art, had a somewhat sticky surface. The differences in surface tack clearly showed after heat load at 90 ° C.
- the films of Comparative Examples 20 and 21 were yellowed and tacky, while the films of Examples 15, 17 and 18 remained colorless and tack-free.
- Comparative Example 19 which is derived from a primary aminosilane was only slightly tacky after heat stress, but it had a typical low elongation at break, which is not sufficient for many applications.
- the triethoxysilane crosslinking Example 16 exhibited slow cure and was therefore still sticky after 14 days. However, under heat load, it hardened well, as evidenced by both the mechanical values and the decrease in tackiness.
