The effect of weathering on surface characteristics of chemically modified scots pine (pinus sylvestris) wood

Scots pine (Pinus sylvestris L.) sapwood of 200×20×80 mm3(L×R×T) was treated with both cell wall filling and lumen filling chemical agents (low-molecular phenol-formaldehyde, bio-oil, N-methylol/N-methyl compounds, sorbitol-citric acid, polysiloxane), which were fixed inside the wooden structure dur...
