Koch-Chemie Plast Shield Psh — Permanent Ceramic Trim Coating, 50 ml

Permanent Ceramic Trim Coating & Color Restoration (Up to 12 Months)

Koch-Chemie Plast Shield Psh is an advanced inorganic ceramic coating formulated specifically to restore, seal, and preserve unpainted exterior plastic components (bumpers, mirror caps, fender arches, wiper scuttles). Unlike temporary silicone dressings that wash off after a few rainstorms, Psh chemically bonds into the porous polymer substrate, restoring deep OEM black depth that endures for up to 12 months.

Key Performance Advantages

• Permanent Molecular Bonding: Does not wash away or streak during vehicle washing or torrential rainfall.
• Intense OEM Color Rejuvenation: Restores chalky, sun-faded grey plastics to an authentic factory semi-matte black.
• Robust UV & Chemical Shield: Protects against harsh UV degradation, road de-icing salts, and alkaline cleaners.
• Superb Hydrophobicity: Dirt, mud, and water easily bead and sheet off treated trim panels.

Recommended Application Protocol

• Preparation: Deep clean trim using Green Star (1:5) and an Allrounder Scrubber to strip all old silicone and road oils. Degrease with Panel Preparation Spray.
• Application: Apply 6–8 drops of Psh onto an Application Sponge or microfiber applicator block.
• Spreading: Work evenly into the textured plastic grain.
• Leveling: After 1–2 minutes, gently wipe off excess with a clean, dry microfiber cloth.
• Curing: Keep dry indoors for at least 12 hours.
