Product Description
Product Overview
This high-performance copolyester hot melt additive enhances mechanical and surface properties of thermosetting powder coating systems including polyester, epoxy, and hybrid resin types. Supplied in granule form, it functions as a thermoplastic modifier that improves flexibility, toughness, and adhesion without interfering with curing chemistry.
Key Features & Benefits
- Enhanced flexibility and toughness - Reduces brittleness in cured coatings and increases resistance to cracking and deformation
- Improved substrate adhesion - Strengthens bonding on difficult surfaces including aluminum, steel, and pretreated metals
- Excellent melt flow and leveling - Promotes better flow during curing for smoother, more uniform surfaces with reduced orange peel
- Thermoplastic reversibility - Enables limited thermal reactivation or reshaping after curing in specific applications

Frequently Asked Questions
Will it affect gloss or color appearance?
Typically improves surface leveling and can help achieve more uniform finishes. However, in high-loading levels, it may slightly affect gloss or haze depending on the base formulation. Testing is recommended.
Can it be used in clear or transparent powder coatings?
Yes, it can be used in clear systems. Its thermoplastic clarity allows for use in transparent or semi-transparent coatings, though optical effects should be validated in formulation trials.
