CHT Wood Coatings

For thousands of years, wood has been a natural, renewable construction material which may be universally applicable but which has also a limited lifetime. For ensuring durable and sustainable wood constructions the material wood must be sufficiently protected and nourished.

Coatings, stains or oils keep moisture as well as microorganisms of plant or animal origin away from the wood, which prolongs the lifetime of the material to a great extent and leads to an appealing look.

Important pre-requisites for this are an optimum application and wetting as well as an unobstructed film formation of the coatings in use. Selected additives and hydrophobic agents of the CHT Group impart an optically and functionally perfect coating.

Typical application fields of the high quality CHT additives in the field of wood coatings:

  • Wood coatings
  • Wood stains
  • Furniture coatings
  • Wood impregnations
  • Wood oils


Our wide range of modern additives listed below supplements and optimises your wood coatings in various ways:

Hydrophobic treatment

  • Control of the surface hydrophobicity and beading effects
  • Reduction of the water absorption

Substrate wetting

  • Improvement of the substrate and pore wetting
  • Prevention of pinholes, craters and other surface defects
  • Increase and improvement of the intercoat adhesion in multi-coat systems

Defoaming and deaerating

  • Foam prevention during pigment grinding and let-down
  • Defoaming during the application

Surface design

  • Prevention of orange peel effects
  • Improvement of the levelling and surface properties
  • Increase of the surface slip
  • Improvement of the scratch resistance
  • Control of the overcoatability


  • Targeted adjustment of the production and printing rheology
  • Improvement of the storability through reduced pigment and filler sedimentation
