RESAMIN® HF 480 Features & Benefits
Applications & Uses
Resamin HF 480 has the properties of a plasticizer as well as that of a soft resin. It contains no organic solvents. It is light-fast and heat resistant and stable against hydrolysis.
Resamin HF 480 is mainly used as a soft resin in nitrocellulose lacquers for the coating of wood and paper to improve flexibility, adhesion, gloss and outdoor durability.
Resamin HF 480 can also be used in stoving systems based on alkyd/amino resins or in coatings based on thermoplastic resins to improve flexibility and adhesion. In combination with thermoplastic resins like Hostaflex (PVC) or Butvar (poly vinyl butyral), pigmentation and gloss development are improved as well.
Because of its excellent compatibility with other binders, there are hardly any problems in processing or milling with pigments and fillers. The dosage of Resamin HF 480 in nitrocellulose lacquers is from 20 % (for paper coatings) to 40 % (for wood coatings), calculated onto solid nitrocellulose. In stoving systems and washprimers, the dosage should not exceed 5 % (on total solids) in view of its strong plasticizing action and threat of surface tack. In most coating formulations, e.g. wash-primers based on Butvar, a dosage of 0.5 to 2% is effective as compatibility promoter. Opalescence resulting from other binders or solvents will disappear if Resamin HF 480 is added.
Technical Details & Test Data
Resamin HF 480 is compatible with most of the synthetic resins used in the coating industry. Resamin HF 480 is unlimited dilutable with aromatic hydrocarbons, esters, glycolethers, ketones and chlorinated hydrocarbons. Resamin HF 480 is largely dilutable with lower alcoholes and aliphatic hydrocarbons.

Storage & Handling
At temperatures up to 25 °C storage stability packed in original containers amounts to at least 1080 days.
A cloudiness, which may occur is reversible and has no effect onto the quality of the product. A short warming to approx. 60 °C will return it to its original state.
