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

Rheology

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