Treatment of particleboard with isocyanate resin to impart improved dimensional stability and water repellency
2000 - IRG/WP 00-40178
Standard particleboard panels (for interior use) of 16 mm nominal thickness were cut into samples measuring 6.4 mm x 78 mm2. The samples were divided into 4 end matched batches. Two batches were treated with isocyanate resin and cured. The other 2 batches were left untreated. One of the treated batched and 1 of the untreated batches were edge sealed with epoxy resin prior to isocyanate resin appli...

The hydrolysis of organo-boron compounds in treated particleborard
2000 - IRG/WP 00-40180
Standard particleboard (manufactured for interior applications) was treated with trimethylborate and modified trimethylborate and then left to hydrolyse for specified periods. The percentage residual trimethylborate was determined by placing samples in kerosene and analysing the kerosene for boron after 3 days of leaching. There was a significant correlation between the percentage hydrolysis of tr...

Soil bed studies of the dimensional stability of composite products
1999 - IRG/WP 99-40134
The influence of boron and isocyanate resin on the dimensional stability of high moisture resistant particleboard was assessed after burial in a soil bed for one month. The samples were treated with two levels of a boron compound and coated in isocyanate resin. The samples were randomly placed in a fungal cellar in soils of two different water holding capacities. Weight differences and dimensional...

The emission of boron compounds from treated particleboard
2000 - IRG/WP 00-40179
The emission of chemical vapours can be harmful both during treatment and service of wood and wood products. Samples of Standard particleboard (for interior use) were treated with trimethylborate, and a number of modified organo-boron compounds. Treated samples were placed immediately under a desiccator lid and air was drawn across each samples to 3 water traps. Water samples were taken after 30, ...
