PHENODUR® PR 909w/50WA

PHENODUR® PR 909w/50WA is a water-dilutable, thermosetting, plasticized phenolic resin primarily used as a binder for the production of solvent-resistant interior coatings for non-food metal packaging goods. Here are the key points from its technical datasheet:

Type: Water dilutable, thermosetting, plasticized phenolic resin

Form of Delivery (f.o.d.): 50% in water (50WA)

Product Data:

• Dynamic Viscosity: 290 - 1490 mPa.s (25 1/s; 23 °C)
• pH-Value: 7.0 - 9.5 (10%)
• Iodine Colour Number: <= 100 (slight opalescence possible)
• Non-Volatile Matter: 48 - 52% (1 h; 125 °C; 2 g)
• Color/Appearance: Dark brown, clear
• Density (Liquids): Approx. 1.10 g/cm³ (20 °C)
• Flash Point: > 100 °C (Pensky-Martens)

Special Properties and Use:

• Used as a sole binder for producing solvent-resistant interior coatings for non-food metal packaging goods.
• Application is typically done by roller- or spray-coating methods.
• Diluted paint pH-value (10%) should be in the range of 8.0 - 8.5, with adjustment made using dimethyl ethanol amine.
• Baking condition: minimum 15 min / 200 °C.

Storage:

• Recommended storage temperature: up to 25 °C.
• Shelf life in original containers: at least 365 days.
• Products containing water may freeze below 0 °C, requiring extended heat treatment for regeneration.

Distinguishing Features:

• Compared to Resydrol AM 410w, PHENODUR® PR 909w/50WA has a lower solvent content and better solvent resistance.

This resin is tailored for specific applications requiring solvent resistance and durability, particularly in non-food metal packaging coatings.
