SYNTEVEN 463 is a medium-reactivity unsaturated polyester resin dissolved in styrene, offering strong flexibilizing properties. It enhances elasticity and adhesion on various substrates like galvanized steel and plastic, and it's suitable for non-"direct polished" polyester systems. Widely used in primers for U.V. photo-curing systems, automotive putties, and direct gloss resin-based paints, it maintains excellent adhesion and sandability without compromising gloss or scratch resistance, making it ideal for demanding industrial sectors. Preliminary compatibility tests are recommended before use.

ROSKYDAL K 65 VT is Amine-accelerated unsaturated polyester resin of high reactivity which is cold-curing, even around 0 °C, and yields highly flexible polymers, to be used as a binder for highly filled, coarse and fine knifing fillers for use on metal, wood and mineral substrates.

DUROFTAL PI 6181/75X can be thinned with esters, ketones, glycol esters and aromatics hydrocarbons. However, the solutions formed must be tested for their storage stability. Prolonged storage of a solution with low binder content may result in turbidity and sedimentation. Only PU grade solvents should be used (< 0.05 % water, free from other reactive impurities).

ROSKYDAL K 60 is a binder for highly filled, coarse and fine knifing fillers with long potlife. ROSKYDAL K 60 enables formulation of fillers with long potlife of 30-45 min. using the standard hardener Di-Benzoylperoxide. ROSKYDAL K 60 is also suitable for fillers with overbaking resistance at temperatures up to 170°C. Fillers based on ROSKYDAL K 60 cure fully when applied in both thin and thick coats.They can be made harder by the addition of e.g. ROSKYDAL K 14 M or ROSKYDAL K 36. Formulation Talc, dolomite/calcite and powdered barytes with low iron content have proven suitable as extenders, with talc as the main component because it improves the adhesion to the substrate. Only coarse and blended talcs should be used to formulate fillers with overbaking resistance up to 170°C.
