Description

Optimised Thinning for Primers

Würth Thinner for Primer is a naptha-based solvent system developed to adjust the viscosity of Würth primer products for brush, spray, or airless spray application. By reducing primer viscosity, it ensures smooth atomisation, even application, and optimum film formation.

Improved Coverage and Finish

When added in correct proportions, the thinner helps primers maintain their specified coverage rate of approx. 5.3m^2 per litre at 75 µm film thickness, preventing runs, orange peel, or uneven film build. This ensures a durable, low-sheen finish suitable for steel structures and fabricated components.

Practical Workshop Use

The thinner is clear, fast-evaporating, and fully compatible with Würth primer coatings. It is easy to incorporate during application preparation and is essential for achieving professional spray results in varying temperature and humidity conditions.

Storage and Stability

Supplied in a robust 5 L container, Würth Thinner for Primer has a shelf life of 12 months when stored correctly. Containers must be tightly sealed and kept in a dry, well-ventilated area at 15–30°C, away from frost, heat, and direct sunlight.

Application Instructions

  1. Mix primer thoroughly before thinning.

  3. Stir thoroughly to ensure even distribution.

  5. Clean application equipment immediately after use with thinner to avoid curing inside tools.
