VYLON GK-360 is a high molecular weight copolyester, with high Tg. VYLON GK-360 has an excellent weather resistance compare to other grades, and has good adhesion to PET and metal substrates. VYLON GK-360 is suitable for can and coil coatings, screen printing inks, primers, coating and adhesion, heat seal lacquers for flexible food packaging. VYLON GK-360 is compliant with FDA 175.105.

ROSKYDAL 500 A is a formulation of clear and pigmented, wax-free coatings for wood and furniture, high-gloss to matt, with good chemical resistance and very good flow properties and scratch resistance. Also in the formulation of spray and curtain-coating fillers for wood, metal and plastic. Coatings based on ROSKYDAL 500 A cure to formhard, scratch-resistant films. The addition of ROSKYDAL 550 (up to 50 %, calculated on the resin supply form) or E 70 (up to 30 %) improves the flexibility and polishability of the films without reducing the scratch resistance. Fillers and putties can be flexibilized with ROSKYDAL E 65 or E 70. The use of ROSKYDAL E 65 is particularly recommended because of its air-drying properties. As is commonwith unsaturated polyester systems, coatings based on ROSKYDAL 500 A are cured with a cobalt/hydroperoxide combination. The cobalt not only splits the peroxide into free radicals but also promotes surface drying. It thus influences two independent but simultaneous reactions. As the breakdown of the hydroperoxide accelerates at higher temperatures, even without the addition of cobalt, it may be necessary to reduce the amount of cobalt added. Otherwise the surface drying will be much quicker than the polymerization of the film, which may result in surface defects. The cobalt/hydroperoxide ratio must be optimized for the formulation, film thickness, application method and drying conditions selected. The standard addition at room temperature is 0.02 - 0.05 % cobalt metal and 1 – 3 %

RESYDROL AZ 6710W/41WA does not contain organic co-solvent and can be used as sole binder for (trim) paints, primers and wood-stains.

SETATHANE D 1150 is applied in the formulation of tough-elastic coatings. It is used in combination with other polyols such as SETATHANE D 1145, 1155 and crosslinked with Desmodur® VL, SETATHANE D 1150 is suitable for use in the formulation of two-component coatings. These are mainly used on concrete and asphalt floors and steel surfaces. After crosslinking and curing of SETATHANE D 1150 with Desmodur VL, the resultant coatings are tough and flexible, hard-wearing and hemicalresistant. It can also be combinedwith Desmodur L to formulate highly resistant sealing compounds.
