D-15 is a clear to yellowish liquid with acrid odor of acetic acid (vinegar).
D-15 catalyst has been specifically formulated to remain liquid at temperatures above 5℃ to permit easier handling in most applications.
|Appearance||clear to light yellow transparent liquid|
|Density at 25℃||1.14g/ml|
|Boiling point at 760mmHg||216.1℃|
|Refractive index (20℃)||1.411|
D-15 readily hydrolyzes upon contact with moisture.
Application and performance
D-15 is transported from the production site as the parent silane to formulators. Generally, D-15is used as a cross-linker at 3% to 5%. As D-15 is compounded into a consumer or industrial sealant or adhesive, it reacts with the silicone. After curing the parent silane becomes cross-linked into the silicone rubber matrix and no longer exists, this greatly reduces the potential for consumer or worker exposure.
D-15 is often the main crosslinker of choice for silicone sealants and can be used by itself or in combination with other acetoxysilane to provide the sealant with targeted properties (such as desired cure rate, adhesion, etc).
The formulation process is similar to that of conventional acetoxysilane systems. In the first step, polymer and silicone oil are mixed and degassed. After that, t Crosslinker D-15 are added and homogenized. After mixing in Crosslinker D-15, mixing should continue for another 15 minutes. After that, the fumed silica, further fillers, pigments are added and homogenized. At the end, Catalyst D-70 is added and mixed in vacuum (150 – 200 mbar).
Product safety, handling and storage
Customers considering the use of this product should review the latest Material Safety Data Sheet and label for product safety information, handling instructions, personal protective equipment if necessary, and any special storage condition required. The “Best use before end” date of each batch is shown on the
product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
