Hardens the surface layer itself
The design targets resistance to peeling, cracking, water, alcohol, heat, abrasion, and mold by strengthening the surface layer rather than relying only on a film.
PRODUCT / PENETRATING POLYMER
Remia
A plant-derived biodegradable penetrating-hardening polymer made by polymerizing pine resin and metal pigments. It penetrates the surface layer of wood and biomaterials, then hardens the material itself.
Remia is a plant-derived varnish for situations where wood must retain its appeal while gaining resistance to water, alcohol, heat, abrasion, and mold.
The name combines Resin, Metal, and the suffix ia. It reflects the calcified-colophonium material design that brings pine resin together with metal pigments.
Many plant- and mycelium-derived biomaterials are inherently vulnerable to water. Remia aims to address that weakness through a plant-derived penetrating-hardening approach.
Material Logic
Why penetrating hardening?
Conventional varnishes protect materials by placing a film on the surface. In harsh environments with frequent scratches and wear, that film can peel away and lose its protective function.
Remia penetrates into the surface structure of wood or bio-leather and then hardens. Instead of only adding a coating, it is designed to reinforce the surface layer of the material itself.
Benefits

03
Three functional values.
Wet gloss with black depth
A very thin application preserves the original look and feel. Layering creates a wet, refined gloss while the transparent black tone adds depth and restraint.
Natural-origin and biodegradable
Remia uses only naturally derived ingredients, aiming for a protective material that does not depend on petroleum-derived resin or microplastic pathways.
Applications
For wood and biomaterials.
MATERIAL
Pine resin / persimmon tannin / iron acetate / slaked lime / natural turpentine oil
FUNCTION
Water, alcohol, heat, abrasion, and mold resistance
FINISH
Thin coat preserves texture / layering adds gloss and depth
REFERENCE
Target price JPY 15,000 / 500 g
The target price reflects the premium wood varnish market while adding value through plant-derived composition, non-petroleum design, heat resistance, and penetrating-hardening durability.
