POLYTONE K-94 is practically acid less, unsaponifiable ketone formaldehyde resin which is very light in colour, has excellent light resistance and show but very slight tendency to solvent retention.
Addition of this resin in general improves gloss, hardness, filling, adhesive strength and durability. Polytone k-94 is available in pearl shaped granules. POLYTONE K-94 is used in the manufacture of flexo graphic inks, gravure inks, lamination inks and ball point pen inks. This resin is highly effective in imparting gloss, adhesiveness in the inks and also in increasing the solid content in flexo & gravure inks. Use of this resin in ball point pen inks ensure that pastes and inks in writing instruments do not dry quickly yet set quickly after writing.
POLYTONE K-94 is used in the manufacture of all types of nitrolacquers and is most suitable for
paper lacquers. This resin is useful in the manufacture of pvc lacquers and for polishing lacquers and finishes for the surface treatment of wooden furniture and articles.
solubility POLYTONE K-94 is soluble in alcohols(not in methanol), ketones, esters, glycol ether acetates, as well as in some aromatic & chlorinated hydrocarbons. It is however not soluble in water and in aliphatic hydrocarbons.
POLYTONE K-94 is compatible with different types of nitrocellulose, cellulose, ethyl cellulose, cellulose acetate, polyvinyl chloride, chlorinated rubber, as well as in many synthetic resins e. G. Alkyd resins, phallic resins, uf resins, polyvinyl butyryl resins, polyamide, phenol formaldehyde condensation resins etc and a multitude of plasticizers.
available in 25 kg bags.
