Peterboro Conservation Mountboards
Peterboro Conservation mountboards are manufactured using the very highest quality facing papers, core board and backing paper. All meet or exceed every aspect of the FATG standard for Conservation mountboard.
Cores are made from chemically purified alpha-cellulose wood fibre which meets the most stringent standards for stability and permanence. The lignin has been removed and it is effectively free of acid.
The face papers have an alkaline-based sizing. None of the materials contain optical brightening agents, OBA’s. They are coloured only with pigments to ensure that the boards comply fully with the standards of durability set and monitored by the Fine Art Trade Guild. No dyes are used.
An alkaline pH of 7.5 - 9.5 is indicated using TAPPI Method T509. Tests conducted using absorption spectroscopy showed a minimum content of 3% calcium and magnesium carbonate buffers.
The extensive colour range includes the very popular Peterboro White, Off-White and Cream shades and many colours which are not available elsewhere.
