A quite revolutionary fine fibred 8.5gsm Japanese fibred tissue coated with an acrylic acid estercopolymer adhesive. This pH neutral tissue support is lignin free, free from hemicelluloses and has a high alpha cellulose content. The ombined pH of the coated heat sensitive tissue is pH 9.6. Filmoplast R has proven itself to have excellent strength and ageing qualities. Simply apply at 80-90ºC for 20-30 seconds. Filmopast R is the ideal choice for making both full and localised archival repairs to manuscripts, paper and charts. Less likely to block than some similar products and easier to reverse, with spirits. Size: 620mm x 50 metres, 24.5 feet x 164 feet
