FAQs About Surface Treatment for Coating Applications
Why is corona treatment important for coating adhesion?
Many substrates used in coating applications have low surface energy, which makes it difficult for coatings to bond effectively. Corona treatment modifies the surface at a microscopic level, increasing surface energy and allowing coatings to adhere more uniformly and durably. Without proper surface treatment, coatings may peel, flake, or fail to cure correctly.
How does surface treatment improve coating performance?
Corona-treated surfaces offer several performance advantages, including:
- Stronger coating adhesion
- Reduced risk of delamination or edge lift
- Improved surface uniformity for consistent coating thickness
- Enhanced durability under handling or environmental stress
It also reduces the need for costly primers or mechanical abrasion steps.
Can corona treatment help with sustainability or process efficiency?
Yes. By improving coating adhesion naturally, corona treatment can reduce or eliminate the need for primers or additional chemical pretreatments. This simplifies the process, reduces material use, and supports more sustainable production by lowering chemical waste and improving coating line efficiency.
Is corona treatment compatible with high-speed coating lines?
Yes. Corona treatment systems from Pillar Technologies are designed for high-speed production and continuous roll-to-roll processing. Our systems can be configured to maintain consistent treatment across the entire web, even at elevated speeds, ensuring high-quality coating application without slowing down your operation.
