ELKEM CAF 530 Black is a black neutral 1K silicone sealant (alkoxy) — primer-free, odorless, corrosion-free for electronics and automotive applications.
The Elkem CAF range comprises one-component (1K), neutral (alkoxy) curing silicone sealants — no acetic acid odor, no corrosion on copper and sensitive metals, ideal for electronics and automotive applications. CAF 530 Black is tailored to specific industrial applications — its key properties and areas of use are listed below.
CAF 530 Black combines the advantages of neutral crosslinking (no copper attack, odorless, primer-free) with the black industry standard color for automotive and electronics applications.

Frequently asked questions about CAF 530 Black
Practical application and design questions — answered by SILITECH.
ELKEM CAF 530 Black: Black neutral 1K silicone sealant (alkoxy) — primer-free, odorless, corrosion-free for electronics and automotive applications. Main applications include electronics with a black finish, automotive black bonding, and headlight bonding.
Neutral curing (alkoxy) means that the 1K system cures through atmospheric moisture, releasing only alcohols (instead of acetic acid). Advantages: no aggressive odor in the workplace, no corrosion on copper, non-ferrous metals, and electrogalvanized steels, very good adhesion to electronic components. Preferred choice for electronics, automotive sensors, solar modules, and all applications with corrosion-sensitive metals.
CAF 530 Black adheres without primer to glass, ceramics, many metals (stainless steel, aluminum, copper in neutral variants), and numerous engineering plastics. Adhesion is not possible to PE, PP, PTFE, and silicone oils—these substrates are fundamentally incompatible with silicone. If in doubt, we recommend a preliminary test or consulting SILITECH regarding the specific material pairing.
Prepare the substrate to be clean, grease-free, and dry. Apply the sealant evenly from the cartridge or container—refer to the TDS for skin formation and curing times. Store in the unopened original container at 5 to 30 °C, protected from sunlight. Use opened containers promptly—for Acetic systems, reseal tightly immediately after opening. Consult the current Safety Data Sheet (SDS) before use.
In the comparison table above, you will find related CAF products with adapted properties—different color, different crosslinking system (acetic vs. neutral), or different mechanical properties. If you are unsure about the optimal choice, we would be happy to advise you—contact SILITECH with your requirements (substrate pairing, temperature, corrosion requirements, appearance).
