Coatings for Wood and Wood-Based Substrates

The special needs of wood as a substrate are considered, with special reference to the coating of wood in buildings and furniture. Coating formulation is set in a context of legislation, operational requirements and the background of European Standards activity.

Description

The course opens with an account of the structure of wood at the microscopic and macroscopic level and the influence this will have on the performance of coatings. Derived products such as MDF and other board products are also considered.

For exterior coatings special emphasis is placed on the issues influencing durability and service life. The hazards facing wood in buildings from moisture, sunlight and biological attack will be linked to the principal lines of defence through good design combined with appropriate surface coatings and preservation treatments. In considering solutions, both maintenance and industrial coating practices will be critically reviewed.

Interior coatings will include flooring and furniture. The need to meet VOC and other legislation has created the need to change from traditional to 'compliant' coatings. Operational factors then become major determinants on the choice of technology, which can include water-borne, high solids, powder and radiation curing.

There will be some flexibility within the course to meet specific interests of attendees.

Who should attend

The course will be useful for those involved in any aspect of formulating or specifying coatings for wood. In the case of buildings this would include the maintenance of existing structures. Detailed technical knowledge is not required.
