Product Information
This material acts as an effective barrier against the common causes of corrosion on aluminium alloys or between dissimilar metals. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas. The uncured material is designed for roller and faying surface sealing applications. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
