HJ-523 Mold release agent

Product Performance

· Low-Pressure Short-Cycle Impregnation: Beyond standard release properties, HJ-523 enhances the flowability of the resin. This reduces surface streaking on the impregnated paper and minimizes uneven resin distribution.

· Phenolic Resin Applications: When used with laminated phenolic resin impregnated papers, it acts as a high-efficiency release agent. Compared to similar products, it requires a significantly lower dosage.

· Key Characteristics: The product features low viscosity, low toxicity, and high stability.

· Ease of Use: HJ-523 is user-friendly and disperses easily within the resin. It provides effective release performance even for minor Urea-Formaldehyde (UF) resin overflows, ensuring a near-perfect impregnation finish for the film.

Application Guidelines

· Phenolic Resin (50% Solid Content): The recommended initial dosage is 0.5%. Once the process is stabilized, the dosage can be gradually reduced to a minimum of 0.3%.

· Melamine Resin: For applications such as impregnated furniture paper, the standard dosage is 0.3%–0.5% of the weight of the second-stage liquid resin.

· Urea-Formaldehyde (UF) Resin: To achieve superior release results, an appropriate amount of the product can be added to the UF resin. An initial dosage of 0.3% is suggested, with the final amount determined by the customer's production evaluation.

Instructions & Precautions

· Mixing: Stir at low speed before use to ensure a uniform mixture.

· Sequence: Important: The release agent must be added to the resin before the curing agent. The curing time should only be tested after the release agent has been fully integrated.
