Application and performance
D-18 is transported from the production site as the parent silane to formulators. Generally, D-18 is used as a cross-linker at 3% to 5%. As D-18 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-18 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).
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.
