Koch Chemie Hydro Plast Care (HPC) is a water-dilutable, solvent-free plastic and rubber care concentrate that gives you complete control over the finish level on interior and exterior surfaces. Dilute it lightly for a natural satin appearance on dashboards, door panels, and exterior trim, or use it at a stronger concentration for a higher sheen on tires and rubber surfaces. One product that adapts to the application and customer preference.

Protects treated plastic, rubber, and vinyl surfaces from UV fading, soiling, and deterioration while refreshing color and restoring a factory-fresh look. Safe on all interior and exterior plastic and rubber surfaces. The subtle vanilla fragrance makes working with it pleasant without being overpowering in an enclosed vehicle interior.

If you are looking for a dilutable plastic and rubber dressing for professional detailing, a UV-protective interior and exterior trim care product with adjustable gloss levels, or a Koch Chemie concentrate that works on both interior dashboards and exterior tires in one bottle, HPC is a versatile and cost-effective addition to any professional detailing product lineup. Available in 1L.

Koch Chemie HPC (Hydro Plast Care) Usage

• Application: Spray onto clean, dry exterior plastic. Wipe to even finish.
• Finish: Satin with hydrophobic beading.
• Durability: ~2 months.

Frequently Asked Questions

Koch Chemie HPC vs Plast Star — which should I choose?

HPC is hydrophobic (water beads off) — great for customers who care about that look. Plast Star is satin without beading, simpler, slightly longer-lasting (2-3 months vs 2). For shop-floor efficiency, Plast Star. For ceramic-package-level detail customers, HPC fits the premium feel.

Is Koch Chemie HPC safe on matte trim?

Yes — it won't add unwanted gloss. HPC finishes to a satin that matches OEM plastic trim. Test a small spot first on any unusual trim material.
