CIOL Wood - Scientific Innovations in Wood Modification for Enhanced Performance and Usage
2025 - IRG/WP 25-20743
CIOL® is a wood modification technology designed as an environmentally friendly alternative to traditional wood preservatives. Utilising a biobased formulation based on sorbitol and citric acid, CIOL® enhances wood's chemical structure, improving its durability, stability, and resistance to decay. This paper provides an overview of the advancements made in CIOL® technology, including its improv...

Performance Verification of Water-Based Outdoor Wood Protection Coatings Based on Weather Resistance Evaluation
2025 - IRG/WP 25-41015
Recent trends in wood protective coatings: Concerns over volatile organic compound (VOC) emissions and the need to reduce maintenance costs have increased demand for environmentally friendly and highly durable coatings. While conventional solvent-based paints are superior in durability, they have been associated with problems such as environmental impact and odour during application. As an alterna...

Enhancing Wood Greying: A Study of Pre-Treatments and Iron(II) Sulphate Application
2025 - IRG/WP 25-41018
Recent trends in architecture and environmental policies have increased the demand for natural, unprotected wood in outdoor applications. However, wood exposed to the elements tends to grey unevenly, which can be problematic for visually important applications like timber façades. One solution is artificial greying with iron ions, providing a uniform colour that later transitions to natural greyi...

Effect of biodiesel-containing solvents on the performance of Copper Naphthenate and Pentachlorophenol: 118-month assessment and depletion analysis
2025 - IRG/WP 25-41022
Solvent systems are incredibly important in determining the performance of oilborne wood preservative systems and they can cause early failures in commodities treated with an otherwise effective preservative system. It is important to assess new solvent performance with oilborne preservative systems to ensure these systems continue to function with the changes. One solvent/preservative combination...

Colorimetric performance of temperate wood species under tropical weathering
2025 - IRG/WP 25-41041
The appearance of wood, including its color and texture, is one of the most important features for its application as solid products, such as furniture, cladding, and terrace decking. Weathering can cause significant changes in the color of wooden products in outdoor applications, influencing their market acceptance and long-term performance. This study evaluated the colorimetric performance of fo...

Migration of polycyclic aromatic hydrocarbons (PAHs) in soil from creosote-treated Douglas-fir and southern pine posts in the first 12 months since installation
2025 - IRG/WP 25-50404
Creosote is a widely used industrial wood preservative largely used for infrastructure-related applications such as utility poles, railway ties, and in marine pilings for protection against fungi, insects, and marine wood borers. Creosote is a coal tar distillate consisting of a complex mixture of organic compounds that together function as a biocide. Polycyclic aromatic hydrocarbons (PAHs) are th...
