[frameconnews] Re: Oil Tempered Hardboard
>>>1 What exactly it is and how it is different from normal
hardboard<<<
Oil tempered hardboard is a fiberboard that has be "tempered" with
oil.
This is a form of hardening. Oil temperd hardboard is smooth on both
sides and has a dark smooth finish.
Regular hardboard is lighter in color and in most cases is smooth on
one side and textured on the other.
>>>2 Is it formaldehyde free<<<
It appears to be. Material Safty Data Sheets for the product indicate
the following ingredients.
Wood Fibers
Paraffin Wax
Clay
Titanium Dioxide
Calcium Carbonate
Talc
Vegtable Oil
>>>3 Is there a downside to using it in conservation framing<<<
Right off the bat, my knee jerk reaction is to never use wood in any
conservation framing other than the frame.
>>>4 Availability in UK<<<
Sorry, can not help with this one as I am in the US.
The oil tempered version is not carried by all lumber yards here. The
last time I bought some, I had to use a specialty yard that caters to
wood workers as opposed to construction.
>>>I believe that hardboard is called Masonite in some countries, and
Ian Marsh's original question probably refers to that<<<
Masonite is a brand name used by the Masonite Corporation. Hardboard
was invented by William Mason in 1924.
