[Product Features]: This series consists of thermoplastic phenolic resins produced by the polycondensation of phenol and formaldehyde. Advantages include good flow, fast curing, high flexural strength, low free-phenol content and resistance to shell peeling. They are mainly used to prepare resin-coated sand for shell molding in foundries.

1. Easy coating, with good coated-sand flow, moisture resistance, high strength and good collapsibility.

2. Low gas evolution, smooth casting surfaces and high dimensional accuracy.

3. High production efficiency, especially suitable for high-volume core production for a single part.

[Applications]: Coated sand for cast iron, ductile iron, general steel castings and non-ferrous castings; also suitable for foundry coatings and specialty zircon coated sand.

[Packaging and Storage]: Packed in 25 kg woven bags. Store in a cool place away from direct sunlight. Do not stack filled bags too high, to avoid caking.
