Talk:Hardboard

Merge
Should they be merged? Masonite is only a type of hardboard so it seems like it could constitute an article in its own with a some more information. -c14


 * The only editor to comment was against it. It's been in place for a few months with no action, so I removed the merge tag. Tom Harrison (talk) 02:17, 4 December 2005 (UTC)

Masonite is different. it contains no resin/glue while Hardboard can. 69.230.109.239 08:08, 21 July 2007 (UTC)

May have a slight difference, but they are so closely related that they should be merged..

Method of tempering
Numerous sources confirm the common method of tempering hardboard by coating with linseed oil & heating, as seen here, here, here, and here for instance. I don't cite these sources in the article because they are primarily commercial sites and the information is not signed, but the immersion method used in the 40s and 50s is now sourced, and I hope to find an authoritative reference for the modern method in the next week. I can find no support for the claim that hardboard is tempered by coating with polyurethane varnish. Ewulp (talk) 07:01, 22 February 2008 (UTC)

My understanding of "tempered hardboard" differs in that a form of oil is used to (in the better products) thoroughly saturate the board, and the heat treating results in the formation of a chemical not unlike phenolic. I cannot find a reference, but most references to hardboard have been clobbered by litigation

(And Masonite corporation (when it made hardboard at all) did indeed make tempered hardboard, as both (dark colored) panels and siding.)drh (talk) 14:40, 25 May 2014 (UTC)
