The main reason why acetoxy cross-linking agents are colored is that trace amounts of methyltriacetoxysilane decompose during the synthesis process, causing the product to be colored. Since the decomposition temperature of methyltriacetoxysilane is only over 100 degrees, the higher the temperature during the synthesis process, the darker the color of the product will be.

Secondly, because there will be certain differences in the amount of decomposition in each batch, the color will also fluctuate. When producing acetoxy sealant, the dosage of cross-linking agent is small, which will not have a major impact on the overall color of the sealant, and the color of the cross-linking agent will not become darker at room temperature, so It will not affect the color of acetoxy transparent silicone sealant.
