Polyester Resins



High-molecular weight copolyesters.

Medium-molecular weight copolyesters.

By developing saturated polyesters, Evonik has played an important role in influencing and extending the possible applications of precoated metals.

These coating raw materials are suitable for the production of coatings with very good adhesion offering an optimum of flexibility and formability together with an excellent surface hardness. For this reason, lacquers based on DYNAPOL® have proved particularly suitable for stampable and deep drawable coatings.

A wide range of products is available for various requirements of the paint and coating industry. DYNAPOL® polyester resins are mainly used for stoving enamels

in combination with amino resins. Special properties, such as chemical resistance, weathering resistance and flexibility, can be improved by using blocked polyisocyanate resins. Stoving enamels based on high- molecular weight copolyesters show particularly good mechanical properties. Medium molecular weight polyester resins containing more hydroxyl groups are suitable for the manufacture of stoving enamels with good reactivity and high solids content. In combination with high- molecular weight copolyesters the quality of films can be optimized.

Depending on the technical requirements and the method of processing,

DYNAPOL® grades can also be used to manufacture industrial coatings.

Saturated polyester resins for stoving enamels



Blocked one pack

polyester-polyurethane systems.

PUR systems

for stoving enamels DYNAPOL® UB systems are made from sa-turated, hydroxylated polyester resins and blocked, cycloaliphatic polyisocyanate crosslinkers.

Evonik pioneered the development of PUR chemistry for coatings and now offers a range of high quality monomers, polyisocyanates, prepolymers and PUR systems based on VESTANAT®. DYNAPOL® UB systems are suitable for the manufacture of industrial coatings, particularly coil coatings with high formability, good surface hardness and outstanding weatherability.

Because of these properties special DYNAPOL® UB types are also used to

formulate high quality, storage stable, 1-pack PUR spray coatings.

The performance profile of DYNAPOL® UB-stoving enamels can be adjusted to the various enduses by suitable paint formulations. Particularly the modification with special Polyamide 12 fine powders (VESTOSINT®) results in special surface textures along with outstanding abrasion resistance and reduced tendency for dirt pick-up.

DYNAPOL® polyesters – your product of choice.

DYNAPOL® for Packaging Coatings

Our paint binders are the products of choice for every paint film on pre-coated rigid metal containers for food and non-food applications. They combine superior protection properties with high flexibility, sterilisation resistance, film hardness and scratch resistance.

Due to their excellent adhesion to various metal and plastic foil substrates our poly-esters are also an essential part, as binder or co-binder, in many kinds of flexible packaging applications like pre-printing primers, printing inks, hot laminating adhesives or as a component for heat- seal laquers.

DYNAPOL® for Coil Coatings

Our paint binders are available to meet every different requirement. Their out-standing performance is the base for safety and reliability when used for wall claddings, roofing, garage doors, blinds, window frames, domestic appliance body housings, ceiling panels, air condition devices, pre-coated automotive parts and any other interior and exterior pre-coated metal application you can imagine.

Methods of determining characteristic values

Glass transition temperature

Determination by DSC method (differential scanning calorimetry)

Molecular mass

Values calculated based on contents of hydroxyl- and carboxyl endgroups

Viscosity number

DIN 53 728. The procedure is to dissolve 0.5 g of the substance in 100 ml of solvent, consisting of 50 parts by weight of phenol and 50 p.b.w. of 1,2-dichlorobenzene, and to measure the efflux time of this solution

in an Ubbelohde capillary viscometer at a temperature of 25 °C.

The viscosity number is calculated with the following formula:

VZ = 100 (cm3/g)

t1 = efflux time of the solution

t2 = efflux time of the solvent

OH value (hydroxyl value)

DIN 53 240-2. Approx. 3 g of polyester are dissolved in dichloromethane. The OH groups contained in the solution are

esteri-fied at room temperature with acetic an-hydride, 4,4-dimethyl amino-pyridine be-ing used as a catalyst. Followbe-ing the hydrolysis of the anhydride, the titration is made using 0.5 N methanolic KOH solution.

Acid value

DIN EN ISO 2114. Approx. 4 g of polyester are dissolved in 50 ml of dichloromethane or tetrahydrofurane.

A titration is made with 0.1 N methanolic or ethanolic KOH with phenolphthalein as indicator.
