In Teknos, we are on our mission to provide technically advanced exterior coating solution to protect wooden windows and doors from sunlight and rain to extend its service life in the tropical climate.

Teknos Coating’s Solution

Teknos waterborne coating products are solvent free, non-flammable and low VOC that minimise the impact to the environment and human health. Unlike solvent based products, waterborne products maintain its elasticity over time which allow the coating film to follow the wood's natural movement without cracking or flaking. Waterborne coatings can be diluted with water to allow viscosity adjustment to attain good flowability in the application and the coating equipment (roller/spray) can be washed by just using water.

Apart from these, Teknos coatings provide good wetting during application and good interlayers adhesion upon curing. The water vapour permeability allows the wood to breathe through the micro-porous coating layers which equilibrates the wood inner moisture along the year. This can greatly reduce the risk of moisture accumulating inside the wood and avoid discolouration and fungal growth.

TEKNOSEAL 4000 (End Grain Sealer)

Teknoseal 4000-00, an aqueous product for sealing of end grain of new wood designated for exterior use; it can be applied by brush and is used to close end grains in both softwood and hardwood species.

AQUA PRIMER (Wood Preservative)

AQUA PRIMER 2907-02 is an aqueous preservative for new untreated wood to enhance wood dimensional stability. The treated area will be protected against wood destroying and wood discolouring fungi and satisfies the performance requirements of EN 599-1. This product can be applied by flow coat, vacumat, dipping (manual or automated), brush machine and brush (manual).

ANTISTAIN AQUA (Tanning Blocker)

ANTISTAIN AQUA 2901 is a waterborne primer for hardwood, and for non-durable hardwood that has been pre-treated with a wood preservative. It reduces surface discoloration, especially on opaque topcoat caused by tannins in hardwood.

AQUATOP (Topcoat)

AQUATOP 2600 is a waterborne topcoat to provide good resistance for outdoor exposure. This topcoat can be applied by all conventional spraying systems - both hand, automated and robot spraying such as airless and airmix spray equipment. It provides good moisture resistance and can typically be applied on pre-treated wood substrates. AQUATOP 2600-23 shows good opacity and less-yellowing film, while dried to a clear and non-hazy film to retain the natural texture and surface characteristics.
