HP RUSTOP 389 is a semi-fluid rust preventive compound specially developed for forging and metal-forming industries that require durable, high-performance corrosion protection. It creates a smooth, yellow-to-brown semi-fluid coating that provides an effective moisture barrier while retaining slight lubricity for mechanical parts. The product’s unique blend of wax-thickened oils and rust inhibitors ensures superior resistance to oxidation and corrosion, making it ideal for protecting forged components, machined surfaces, and heavy-duty assemblies during transit or interim storage. HP RUSTOP 389’s film remains stable over wide temperature variations and resists hardening, ensuring easy removal when the part is ready for use. Its high flash point and excellent compatibility with other lubricants make it a safe and efficient choice for industrial operations demanding long-lasting, non-tacky, and residue-free rust protection.
