Introducing TRI-Funori™

TRI-Funori™ is a new conservation product that is effective in three distinct areas of application: as a fixative, as a cleaning agent, and as a light adhesive.

TRI-Funori is derived from two species (Gloiopeltis furcata and Gloiopeltis tenax) of red seaweed (“funori” in Japanese) harvested along the coast of Japan. The key component of the seaweed is a unique polysaccharide starch. HPCS imports the raw untreated funori directly from Japanese harvesters and extracts the starchy material using simple mechanical processes.

The characteristic that makes this polysaccharide starch valuable is its interesting ability to bind large amounts of water relative to its mass. This means that it does not wet the surface to which it is applied. In turn, it does not mobilize salts and therefore does not leave tide lines.

As a fixative, it dries matte. As an adhesive, it is fully reversible with water. These performance characteristics are why funori has had such a long tradition of use in the conservation of books, paper and art objects.

TRI-Funori is packaged in a Faraday Shield re-sealable vacuum bag. Unopened shelf life can be measured in years.

Most importantly, TRI-Funori maintains the same properties and performance characteristics that made the liquid product so successful.


TProduct and PackagingRI-Funori™ is available in 1, 5 and 15 gram quantities as well as a 3 litre liquid “Bag in a Box” for large scale architectural projects.
