Fast Drying Acrylic SR-10: High-Productivity Flexographic Varnish for Paper
The SR-10 acrylic varnish is a technical flexographic overprint coating designed to optimize print quality on all types of paper. Its ultra-fast drying water-based formulation provides superior surface protection, visual enhancement of colors, and high mechanical resistance. It is specifically engineered for high-performance flexographic lines, drastically reducing waiting times and maximizing the overall efficiency of the packaging and label production process.
Operational Advantages on Press
- Ultra-Fast Drying: Minimizes process and in-line curing times, ideal for long runs and high-speed machinery without the risk of set-off.
- Aesthetic Improvement & Flexibility: Provides uniform gloss and strong printed color pop; additionally, it offers the option of a matte finish formulation upon request.
- Advanced Functional Protection: Significantly reduces the risk of scratching, abrasion, and mechanical wear during the handling and transport of the finished product.
- Universal Compatibility: Guarantees excellent adhesion over flexographic inks and all types of paper substrates (coated, uncoated, and recycled).
- Sustainable and Operational Profile: Its water-based formulation ensures low volatile organic compound (VOC) emissions and allows for quick and easy press cleaning.

Recommended Uses, Logistics, and Regulations
- Main Applications: Ideal for food and non-food paper/cardboard packaging, labels, folding cartons, wrappers, and graphic applications requiring high visual standards.
- Food Contact Compliance: Complies with EU Reg. (EC) 1935/2004 and Reg. (EC) 2023/2006 (Good Manufacturing Practice). Specific migration validation is required if intended for indirect food contact.
- Technical Considerations: It is always recommended to test compatibility over specific inks and papers, as well as to verify resistances in post-processing procedures (die-cutting, folding, and friction).
- Usage Recommendation: A joint validation plan with the client is suggested to ensure the finish, mechanical resistance, and in-line performance based on the complete structure of the packaging.
