THCMB 100% Cotton Core 550 - TG Offwhite

Designed for conservation, this 100% Cotton Museum Board has set the standard for the highest specification of museum mounting since the early 1980s and from that time has been the board of choice for major museums in Great Britain and Europe. Cotton is ‘born’ pure being almost 100% pure alpha cellulose and therefore requires less processing than wood sourced fibres.

Specified by the founder of Conservation By Design, it was the world’s first board to be laminated with EVA plasticiser-free adhesive which is more resistant to acid hydrolysis than other cheaper synthetic adhesives. This is important if you are looking for the maximum level of protection because, if the adhesive breaks down and ‘off-gasses’ in the micro environment of a frame or a box, the object enclosed may be damaged. The board passes the PAT and Silver Tarnish Test and is therefore suitable for all media including photographs. This board combines the utmost purity with excellent cutting and erasion properties. Surface absorption is appropriate for washline mounts because of the special sizing applied to the surface of the paper.

For mounting certain types of photograph such as gelatine, albumen and dye transfer prints, which prefer a less alkaline environment, TG - Off White and Dull White is offered in an unbuffered version.

Unbuffered boards are also used by textile conservators for the mounting and storage of wool and silk.

The standard alkaline buffered board is available in Museum Cream, Off White and White.
