APPLICATION GUIDE

Waterborne Polyurethane for Automotive Interior Leather

Waterborne polyurethane and finishing-material selection for automotive seat and interior leather systems where durability, surface consistency and environmental performance are important.

Material-selection priorities

Final formulation and model selection depends on substrate, coating structure, process conditions and end-use testing. The priorities below are intended for technical scoping, not as a substitute for customer validation.

  • Abrasion and scratch resistance
  • Hydrolysis resistance
  • Light / aging resistance
  • Matte or controlled surface appearance
  • Low-emission system design subject to validated formulation data

Current documented product matches

FAST does not add unsupported performance or compliance promises to application pages. For project-specific VOC, DMF, weathering or other compliance targets, provide the target standard in your inquiry so FAST can respond against specific products and documents.
AUTOMOTIVE STARTING POINTS

Browse by coating role before choosing a model

Current FAST catalog data supports several different automotive-interior entry points. The correct route depends on whether the need is foaming/base structure, topcoat performance or a matte surface.

BASE

RU-5506 foaming resin

Aliphatic foaming resin direction with soft hand, rebound, peel, yellowing and weather-resistance support in current catalog data.

TOPCOAT

RU-6730–6750 family

Topcoat grades with documented abrasion, cold, flex, yellowing, leveling, gloss or wet/dry-rub directions depending on model.

MATTE

RU-6830 / 6860 / 6870 / 6880

Matte grades for automotive/furniture directions, including abrasion/scratch and selected hydrolysis-resistant polycarbonate-based options.
