1- Resins for Air Drying

Long oil alkyd resins• DIY• Cost–effectives alkyd resins • Public furniture and wooden doors- gloss or matt varnish

Urethanated oil & alkyd resins• DIY• Outdoor garden furniture• Interior parquet floor and wooden door with excellent hardness and abrasion resistance

2- Resins for Nitrocellulose

• Fast drying system with excellent quality in combination with nitrocellulose resin• NC sanding sealer & NC varnish for interior house furniture and o�ce furniture

3- Resins for 2K PU

Moved from NC to 2K PU to get higher performance, excellent chemical, abrasion and alcohol resistance of �nish coating.

Alkyd resins for 2K PU • Short alkyd resins used for formulation of 2K PU sanding sealer & 2K PU varnish for high quality excellent durability 2K PU system finish.• Interior house furniture, office furniture and parquet floor gloss and matt

N.B. for high gloss finishes you can use unsaturated polyester sealer as a prime coat.

Hydroxy acrylic resins for 2K PU • High quality, excellent durability, high chemicals and solvent resistance• High resistance for blocking with excellent flexibility• Varnish with hard thin layer to show the wood grown

4- Resins for Unsaturated Polyester Filler

• Excellent filling power and durability• Can be cured even at high film thickness • Help to have finish coat with mirror effect (dry film thickness = wet �lm thickness)

5- Resins for Acid Curing Varnishes

• Hard, durable, clear finish designed for professional application of wood flooring • High scratch, solvents and heat resistances.• Disadvantage of this system is the undesirable formalde- hyde emission into the surrounding during the curing process.
