Crosslinker XP AC 30 Methyl triacetoxysilane Hanse Chemie Crosslinking / Coupling / Curing Agents >> Silane Silicones (Si) SEALANT The Crosslinkers AC are liquid crosslinkers for 1-part silicone sealants. With the addition of a suitable catalyst (such as Catalyst TA 12) OH-functional silicone polymers crosslink in the presence of ambient humidity, while releasing acetic acid. Acetate crosslinkers give sealants with the following characteristics: Very good adhesion on many substrates (e.g. glass, ceramics, metal, plastics) Very good transparency Very good storage stability Acetoxy silane sealants have been used for decades in many applications in the sanitary and construction industries, and are still the best-known silicone sealant crosslinkers. mixture with methyl triacetoxysilane. Ethyl and methyl triacetoxysilanes differ in their reactivity. Methyl triacetoxysilane is substantially more reactive than the corresponding ethyl triacetoxysilane. Therefore, as the proportion of methyl components rises in the above mixtures, the reactivity increases as well. Since methyl triacetoxysilane is solid at room temperature, high proportions of this component raise the melting point Functional acetoxysilane crosslinker. Used for 1-part silicone sealants in the sanitary and construction industries. Provides adhesion on many substrates, transparency and storage stability. Offers high reactivity. Solid at room temperature.
