Product Description

Product Overview

Polyester Acrylate 5312 is a high-performance UV resin featuring excellent compatibility with most UV monomers and resins. Specially engineered for large-area spraying, printing varnishes, and inks, it provides a comprehensive balance of performance attributes, including fast curing speed, superior leveling, excellent ink wettability, high gloss, and robust substrate adhesion—serving as a premier choice for industrial coatings and graphic printing applications.

Designed to streamline high-throughput production lines, Polyester Acrylate 5312 delivers elevated production efficiency, refined aesthetics, and long-term film durability across multiple industrial formulations.

Key Performance Advantages
Fast Curing Speed

Promotes instantaneous film formation under UV irradiation, notably reducing production cycles and optimizing throughput in automated lines.

Superior Leveling

Flows out uniformly during application to eliminate common surface imperfections such as brush marks, orange peel, or streaks.

Good Ink Wettability

Facilitates seamless pigment wetting and substrate compatibility, generating sharper print definition and vivid color rendering.

High Gloss Finish

Cures to a crystal-clear, mirror-like gloss with full-bodied optical depth that elevates overall finished part aesthetics.

Strong Adhesion

Establishes a firm, cohesive bond to diverse substrates, effectively mitigating risks of peeling, edge lifting, or delamination.

Frequently Asked Questions (FAQ)
What resin classification does 5312 belong to?

Polyester Acrylate 5312 is a trifunctional (functionality 3) polyester acrylate UV resin presented as a transparent viscous liquid with excellent broad-range compatibility.

What makes 5312 suitable for high-speed printing and large-area spraying?

Its fast UV curing speed accelerates film drying times, while its self-leveling behavior ensures uniform coverage without surface streaks, directly boosting processing speed and operational efficiency.

What are the standard viscosity and acid values for this UV resin?

Polyester Acrylate 5312 has a standard viscosity range of 400~1500 mPa.s at 25ºC and an acid value of ≤5 mgKOH/g, with a chrominance rating ≤50 Pt-Co.

Why must a 15% air headspace be maintained in storage containers?

Oxygen is an essential stabilizer for acrylic double bonds in UV systems. Leaving at least 15% air space prevents unintended dark polymerization during shipping and storage.

What packaging sizes are offered, and what is the shelf life?

The product is supplied in 20 kg or 200 kg closed standard steel drums with a guaranteed warranty period of 90 days when stored properly below 35°C away from sunlight.
