Enhancing Flexibility in UV OPV Paper Formulations with SOLVACOAT RAD 442

Polyester acrylate resins are widely used in various UV coating applications due to their excellent balance of flexibility, adhesion, and film-forming properties. These resins are particularly valued for their ability to enhance the durability of coatings while maintaining critical characteristics like gloss and adhesion. Polyester acrylates are known for their low viscosity, which makes them easy to handle during formulation, and they excel in applications where flexibility is a priority, such as in paper, wood, and plastic coatings.

In UV overprint varnishes (OPVs), polyester acrylate resins offer enhanced flexibility without compromising the coating’s optical properties, such as gloss. This makes them highly sought after in industries that demand both high-performance coatings and visual appeal. 

Introducing Solvacoat RAD 442 To Enhance UV Coatings Flexibility

Maha Solvacoat RAD 442 is a two-functional polyester acrylate oligomer that is specially designed to meet the high demands of UV OPV formulations. It brings a unique set of features that make it ideal for manufacturers looking for a balance between flexibility, gloss, and ease of formulation.

Key Features of SOLVACOAT RAD 442

1. Excellent Flexibility Without Compromising Gloss One of the biggest challenges in UV OPV formulations is to maintain both flexibility and a high-gloss finish. SOLVACOAT RAD 442 addresses this perfectly by offering high flexibility, which prevents cracking and peeling, while preserving the desired gloss level.
2. Good Adhesion and Leveling Adhesion and levelling are critical factors in ensuring a uniform, high-quality finish. SOLVACOAT RAD 442 maintains a good offer in both areas, providing strong adhesion to a variety of substrates, including wood, and paper. Its excellent leveling properties ensure a smooth, even coating without defects.
3. Ultra-Low Viscosity for Easy Handling The ultra-low viscosity of SOLVACOAT RAD 442 simplifies the process of adding it to formulations, making it easier to blend with other components. This characteristic enhances production efficiency while delivering consistent, high-quality results.
4. Cost-Effective and Versatile In addition to its performance benefits, SOLVACOAT RAD 442 is a cost-effective option. Its high solid content and low viscosity mean formulators can achieve optimal results with minimal effort, making it a valuable solution for budget-conscious manufacturers. Moreover, it can partially replace TPGDA, providing even more flexibility and cost savings.
