High-solids, solvent-borne unsaturated polyester resin designed for excellent flow and leveling in coil coating systems.
Optimized for fast cure kinetics under standard industrial coil line conditions (e.g., 250–300 °C peak metal temperature).
Delivers outstanding gloss retention, hardness development, and resistance to humidity and UV-induced chalking.
Compatible with common amino crosslinkers (e.g., melamine-formaldehyde) and conventional coil coating additives.
Consistent batch-to-batch performance with tight control on acid value and viscosity for reliable production stability.
Prefinished metal substrates for architectural wall panels and roofing systems.
Appliance front panels requiring high-gloss, durable decorative finishes.
Industrial HVAC enclosures exposed to thermal cycling and atmospheric weathering.
Automotive non-structural trim components requiring coil-coated aesthetics and corrosion protection.

Q1: What is the primary application area for DUROFTAL PE 912 60SNA?
A: DUROFTAL PE 912 60SNA is a solvent-based unsaturated polyester resin designed primarily for high-performance coil coating and metal decorating systems, where excellent gloss retention, hardness development, and resistance to weathering and chemical exposure are required.
Q2: Is this resin suitable for low-bake curing applications?
A: Yes, DUROFTAL PE 912 60SNA is formulated to achieve full crosslinking at relatively low cure temperatures—typically in the range of 180–220 °C—making it well-suited for continuous metal coil lines with constrained thermal budgets.
Q3: How does PE 912 60SNA differ from conventional polyester resins used in coil coatings?
A: Unlike standard saturated polyesters, PE 912 60SNA incorporates a tailored unsaturation profile and molecular architecture that enables rapid film formation, enhanced crosslink density, and superior mechanical properties—particularly flexibility and impact resistance—without compromising surface hardness or gloss stability.
Q4: What solvents are recommended for diluting this resin?
A: DUROFTAL PE 912 60SNA is compatible with common aromatic and ketonic solvents such as xylene, Solvesso™ 100, methyl isobutyl ketone (MIBK), and butyl acetate. Solvent selection should be based on desired viscosity, evaporation rate, and compatibility with the full formulation—including crosslinkers and additives.
Q5: Can PE 912 60SNA be used in combination with melamine-formaldehyde crosslinkers?
A: Yes, it is specifically engineered for use with high-alkylated melamine resins, delivering excellent cure response, storage stability in one-component systems, and balanced performance across flexibility, hardness, and chemical resistance.
