6 74 Timecare Heritage conservation quality Designed for conservation, this 100% Cotton Museum Board has set the standard for the highest specification of Museum mounting. Cotton is born pure being almost 100% pure alpha cellulose and therefore requires less processing than wood sourced fibres. It is laminated with EVA plasticiser-free adhesive which is more resistant to acid hydrolysis than other cheaper synthetic adhesives. The board passes the and Silver Tarnish tests and is therefore suitable for all media including photographs. This board combines the utmost purity with excellent cutting and erosion properties. Surface absorption is appropriate for wash line mounts because of the special sizing applied to the surface of the paper.

7 Patrimony Timecare Conservation quality 75 An economical alternative to cotton board, made from high quality chemically purified wood fibres. High in alpha cellulose, buffered with calcium carbonate to resist air-borne pollution and to maintain a neutral environment around the object. The paper is neutral sized internally with AKD and externally with starch. It is 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 gases i.e. acetic acid in the micro-environment of a frame or a box the object enclosed will be damaged. The board may be easily cut and gives a smooth edge which will maintain its colour without yellowing throughout the life of the board. The board is suitable for ink and wash line decoration because of the surface sizing of the paper.. Chemically purified wood fibre. High alpha cellulose content. ph 7,5 to 9.

14 82 Corrugated Microchannel Premier TM Premier Archival Fluted Boxboard is a high quality corrugated board made from the same acid and lignin-free long fibred conservation quality paper used to make the solid centre Premier Archival Folding Boxboard. Offered in 3 styles of flute construction. Because of its fluted structure corrugated board has the advantages of being lightweight yet rigid. It has many applications and is particularly useful for oversized boxes. Conservation By Design s Heritage Archival photokraft papers (HAPK) are used to make this board, they meet European and American standards for Archival Long Life Papers and Boards.

Test and have excellent water resistance having being internally sized with AKD and externally with starch. The high percentage of long kraft fibres gives enhanced fold and tear strength to the board. Corrugated boxes, when produced in volume, offer a lower cost and good protection against handling. This is why they are used for commercial packaging/ shipping and display applications.

20 88 Gatorfoam Gatorfoam is an extremely rigid lightweight composite display board which combines excellent strength-to-weight values and versatility with archival quality which allows its use for display mounting of museum artefacts and materials requiring a non-acidic environment. Resin impregnated, chemically purified wood pulp boards are bonded to both sides of a high density, smooth-cutting polystyrene core. The smooth finish board accepts screen printing, acrylic and oil paint, and is sufficiently water resistant to withstand exterior use. Uniform density allows cutting by hand and power tools, use of screw or wire fixings, and a variety of adhesives and laminating fabrics. When mounting acid-intolerant material for prolonged display it is advisable to laminate the mounting surface of Gatorfoam with an alkaline paper or board mm White Sheet X White X White x White x White 15.
