Case Studies
Surface Coating Blending
A multinational company required a cost-effective 2mm granule of a waxy product used as surface coating additive .
The product had not been previously extruded. The material was supplied as a waxy solid block with a melting point below 100 ºC.
The material also required careful handling as it was corrosive and a significant aim was to reduce contact hazards.
Surface Coating Additive Milling
Exwold was approached by a leading chemical company to process a range of automotive surface coating additives.
The surface coating additive is produced as a molten solid in drums. Once cooled it forms a waxy, solid mass. The material has a low melting point <50ºC. The client required this in physical form to charge into coating with a specific particle size distribution to ensure dispersion.
Coating Processing
A powder coating manufacturer contacted us to establish whether a process could be established to recycle fines (the fine powder generated and removed during powder coating manufacture).
The company was sending around 10-25mt of fines to landfill each year and wanted to reduce the environmental and financial impact. The fines ranged in PSD but were typically 150 microns.

ESG Report 2025
Our ESG Report embodies our commitment to sustainability, ethical business practices, and transparency. Through this report, we detail how we measure and manage our environmental impact, uphold human rights and employee well-being, and enforce high standards of corporate governance. By doing so, we build trust with stakeholders and demonstrate accountability, showing that profitability and responsibility can go hand in hand.
Particle Size Distribution
Particle Size Distribution (PSD) is a key factor that determines how powders and granular materials behave during processing and final use. Even with identical chemistry, variations can affect flow, stability, reactivity, and product appearance.
This guide outlines what PSD is, why it matters, and how effective measurement and control lead to greater efficiencies and quality.
