Expert Line — Finishing Additive

Leather Thickening Agent

Professional water-based thickening additive for leather finishing systems. Increases viscosity and tunes rheology without affecting colour clarity, transparency, drying time or inter-coat adhesion when used as directed.

  • Viscosity Control
  • Prevents Runs & Sags
  • Preserves Clarity
  • Water-Based System

What It Does

Leather Thickening Agent is a functional polyurethane-based additive for water-borne leather systems. It raises viscosity and stabilises flow so coatings level cleanly, edges stay tidy, and vertical panels are less prone to drips or sags — all while preserving transparency and colour accuracy.

The additive does not change drying time of film-forming finishes and does not degrade inter-coat adhesion when used correctly.


Professional Applications

  • High-gloss finishing: added into Leather Top Coat Gloss to create a super-gloss finish — essential for patent-leather shoe restoration.
  • Vertical surfaces: reduce runs and improve edge control on seats, side panels and trim.
  • Process tuning: adjust brush/spray workflow where a slightly thicker, more controlled laydown is desired.

Use strictly within recommended ranges and test on a small panel before full application.


Compatible Products

  • Leather Colourant — water-based leather colourant.
  • Leather Top Coat — water-based protective finishes (e.g., Gloss for super-gloss builds).
  • Heavy Filler / Light Filler — repair compounds.

Add gradually and mix thoroughly to achieve target viscosity.


Technical Specifications

Parameter Value
Type Water-based thickening additive for polyurethane dispersions
System Water-borne leather coatings and compounds
Dosage (by volume) 1–5 % into Leather Colourant, Leather Top Coat, Heavy/Light Filler
Effect on finish Preserves transparency & colour; does not alter drying time; does not reduce inter-coat adhesion
Form Ready to use; pre-dilution not required

Tips & Notes

  • Start at the low end (≈1 %) and build up in small steps to avoid over-thickening.
  • Evaluate sprayability/levelling on a test panel before full-scale application.
  • For super-gloss builds on patent-leather restorations, use with Leather Top Coat Gloss.

Trusted by professional refinishers, LeTech finishing additives deliver precise control with clean results. Leather Thickening Agent integrates seamlessly into water-borne colourants, top coats and repair compounds to help you work faster, cleaner and with greater consistency.

How to Use — Step by Step

  1. Prepare: Bring the host product (Leather Colourant / Leather Top Coat / Heavy or Light Filler) to room temperature.
  2. Start low: Add ≈1 % Thickening Agent by volume.
  3. Mix thoroughly: Stir until completely homogeneous.
  4. Assess: Check viscosity, flow and sprayability/brush feel on a test panel.
  5. Adjust if needed: Increase gradually up to max 5 %, re-testing after each step.
  6. Apply as usual: Follow the host product’s application and drying schedule.
  7. Notes: Over-thickening can cause poor levelling. The additive does not change drying time and does not reduce inter-coat adhesion when used as directed.
  8. Safety: Always test on a hidden area. Work in a ventilated space and follow standard PPE for coatings.
