Uviflex Mate SP-077 RT: UV Matte Flexographic Varnish for High Resistance and Flexibility
The Uviflex Mate SP-077 RT UV matte flexographic varnish is a high-performance coating designed for instant curing via ultraviolet light. It creates a flexible layer with an elegant, anti-reflective matte finish, providing exceptional chemical resistance to alcohols, cleaning agents, and greases, as well as high scratch and abrasion resistance. Formulated to ensure no loss of durability or inline productivity, this varnish is ideal for premium packaging, folding cartons, labels, and materials subjected to intense mechanical handling or direct contact with chemical agents.
Operational Advantages on Press
- Premium matte and anti-reflective finish: Delivers a sophisticated, high-quality corporate image, substantially improving readability on dark backgrounds and fine texts.
- Superior chemical and mechanical resistance: Ensures total protection against alcohols, mild detergents, oils, and greases, keeping the print flawless during use, transport, and post-production processes thanks to its scratch and abrasion tolerance.
- Structural flexible layer: Its formulation allows application on substrates intended for folding, creasing, and shaping without causing micro-cracking.
- Instant UV curing: Optimizes productivity, offering maximum stability and speed on UV flexography lines.

Logistics and Handling
- Equipment and Post-production: Strict control of UV (or LED) dose and irradiance is essential to ensure complete curing and guarantee resistance properties. It exhibits excellent behavior in die-cutting, cutting, and creasing processes, allowing for COF verification and adjustment according to the needs of automatic lines and stacking.
- Storage: Keep in original, tightly closed containers. Store in dry, well-ventilated areas away from direct sunlight, any source of UV emission, and heat.
- Shelf Life: Consult the batch-specific technical data sheet to determine the months of viability under optimal storage conditions.
- Regulatory and Safety: For applications intended for sensitive sectors such as food or cosmetics, it is necessary to confirm migration suitability according to applicable legal regulations and conduct prior internal testing.
