AcryPeak1060 Thermoplastic Methacrylate Copolymer – TDS, Properties & Applications
Meta Description: AcryPeak1060 is a thermoplastic methacrylate copolymer with high adhesion, low acid value, and good heat and moisture resistance. Learn its typical properties, compatibility, and uses in 3C coatings, metal coatings, UV coatings, and IMD inks.
Introduction
AcryPeak1060 is a thermoplastic acrylic resin supplied as solid crystal granules. Chemically, it is a methacrylate copolymer with 100% effective content. According to the product technical data sheet (TDS), it is designed for plastic coatings, metal coatings, ceramic and inorganic composite surfaces. It can also be used in UV coating and UV ink systems.
This article summarizes the typical properties, performance characteristics, compatibility, and application considerations of AcryPeak1060 for formulators and coating engineers.
Product Overview
AcryPeak1060 is positioned mainly in two roles. First, it can be used as a main resin in 3C electronic plastic surface coatings. Second, it can be used as a co-resin in metal coatings to improve metal adhesion, or as a functional additive in UV systems to improve adhesion and reduce volume shrinkage.
The resin dissolves in esters, aromatic hydrocarbons, and alcohol ethers. It is not soluble in a single alcohol solvent, but it can dissolve in mixed solvents containing alcohol and ether. This gives formulators flexibility when designing solvent-borne systems.
Typical Properties
The following values are typical values from the TDS. Actual batch data should be confirmed with the certificate of analysis (COA).
| Property | Typical Value | Unit |
|---|---|---|
| Appearance | Crystal granules | - |
| Tg | 65 | °C |
| Molecular weight (GPC) | 15,000 | - |
| Elongation at break | 50 | % |
| Colour, Gardner | 1 | - |
| Acid value | max. 5 | mg KOH/g |
| Density | 1.05 | g/cm³ |
| Effective content | 100 | % |
| Packing | 25 | kg/drum |
Tg 65°C is a medium-to-high glass transition temperature for a thermoplastic acrylic resin. It can support anti-blocking and dimensional stability at room temperature. The 50% elongation at break provides a useful level of flexibility.
The acid value of max. 5 mg KOH/g is low. Low acid value is generally helpful for water and moisture resistance because there are fewer hydrophilic carboxyl groups. The molecular weight of 15,000 (GPC) is moderate, offering a balance between solubility, application viscosity, and film formation.
Key Performance Characteristics
Adhesion
AcryPeak1060 is described in the TDS as a high-adhesion thermoplastic acrylic resin. It is suitable for plastic, metal, ceramic, and inorganic composite substrates. In metal coatings, it can be used as a co-resin to improve adhesion to metal surfaces.
Moisture and Boiling Water Resistance
The TDS states that AcryPeak1060 provides good resistance to humid heat and stringent boiling water testing. The low acid value may contribute to this performance. However, final water resistance depends on the full formulation, crosslink density, substrate preparation, and curing conditions.
High-Temperature Baking
AcryPeak1060 shows no yellowing and no cracking in 210°C high-temperature baking tests. This makes it suitable for applications that require high-temperature post-baking or high-temperature processing.
Use in UV Systems
AcryPeak1060 dissolves quickly in UV-curable monomers. When added to UV coatings, it can help improve adhesion, reduce volume shrinkage, and maintain moisture and boiling resistance. This is useful for UV coatings on plated or oxidized metal surfaces, where shrinkage can affect adhesion.
Main Applications
3C Electronic Plastic Coatings
AcryPeak1060 can be used as a main resin in 3C electronic plastic surface coatings. It is suitable for common plastic substrates such as ABS, PC, and HIPS when used with appropriate solvents and additives.
Metal Coatings
In metal coating systems, AcryPeak1060 can be blended with polyester, epoxy, polyurethane, phosphate ester, and acrylate polymers. It helps improve metal adhesion and can be used to adjust formulation performance.
UV Coatings
In UV coatings, AcryPeak1060 can improve adhesion to plating and oxidized metal surfaces while reducing cure shrinkage. It is suitable for UV primer and topcoat systems where adhesion is important.
UV Inks
In IMD high-stretch molding inks, AcryPeak1060 can help improve thermal shock resistance and elongation. The 50% elongation at break supports flexibility during thermoforming and injection molding. It can also be used in printing inks for metal coatings or high-hardness surfaces.
Compatibility and Solubility
Monomers: Miscible with conventional monomers.
Solvents: Miscible with esters, ketones, and aromatic hydrocarbons. Not soluble in single alcohol solvents. Soluble in mixed solvents containing alcohol and ether.
Polymers: Compatible with polyester, epoxy, polyurethane, phosphate ester, and acrylate polymers. This makes it suitable for formulation adjustment.
Formulation and Handling Notes
Use ester, ketone, aromatic, or alcohol-ether mixed solvents.
Add resin granules slowly with agitation to avoid lumping.
Pre-test compatibility when blending with other resins.
The 210°C baking data is a typical value. Actual performance depends on film thickness, baking time, and formulation.
Packing: 25 kg per drum.
More detailed application references and MSDS are available from the supplier.
Selection Considerations
AcryPeak1060 may be suitable for:
Solvent-borne thermoplastic acrylic coatings requiring medium Tg and low acid value.
Metal coating formulations needing improved adhesion.
UV systems requiring reduced shrinkage and improved adhesion.
IMD high-stretch UV inks requiring thermal shock resistance and elongation.
Summary
AcryPeak1060 is a thermoplastic methacrylate copolymer with a balanced property profile. Its key features include high adhesion, low acid value, light color, good compatibility, moisture and boiling water resistance, and 210°C baking resistance without yellowing or cracking. For 3C plastic coatings, metal coatings, UV coatings, and IMD inks, it is a product worth evaluating. Final performance should always be verified in the complete formulation.
