High Viscosity UV Coating — TWGU6400 UV High Gloss Ink Duct

TWGU6400 is a specialist high viscosity UV high gloss coating formulated for application via the ink duct on commercial offset printing presses. Unlike standard UV coatings applied through the coating tower, this high viscosity formulation is designed to run through the offset ink duct system, allowing UV gloss coating to be applied in-line using a standard offset printing unit for applications where a dedicated coating tower is not available.

Engineered for reliable performance on commercial sheet-fed offset presses, TWGU6400 delivers excellent gloss levels and rub resistance with the convenience of ink duct application, providing UK commercial printers with a flexible in-line UV gloss coating solution.

Key Features:

• Ink Duct Application: High viscosity formulation specifically designed for application via the offset press ink duct rather than a coating tower.
• High Gloss Performance: Delivers excellent UV gloss levels for enhanced visual impact on commercial print and packaging.
• UV Curable: Cures instantly under UV lamps for efficient in-line gloss coating on commercial offset presses.
• Offset Press Compatible: Formulated for reliable performance on commercial sheet-fed offset printing presses.
• Excellent Rub Resistance: Provides durable, scuff-resistant gloss coating on commercial print and packaging substrates.

TWGU6400 is the specialist high viscosity UV ink duct coating for UK commercial offset printers requiring in-line UV gloss coating performance without a dedicated coating tower.

Frequently Asked Questions

What is high viscosity UV coating used for in commercial printing?

High viscosity UV coating such as TWGU6400 is specifically formulated for application via the ink duct on a commercial offset press, rather than through a dedicated coating tower. This allows UV gloss coating to be applied in-line using a standard printing unit, making it ideal for presses without a separate coating tower.

How does high viscosity UV coating differ from standard UV coatings for printing?

Standard UV coatings for commercial printing are typically low viscosity formulations applied via a dedicated coating tower on the offset press. TWGU6400 is a high viscosity formulation specifically engineered for application through the offset press ink duct, providing an in-line UV gloss coating solution without requiring a separate coating unit.

What are the best practices for applying high viscosity UV coating on an offset press?

TWGU6400 should be applied via the ink duct in a similar manner to offset ink, with the coating unit configured appropriately for the coating viscosity and target coating weight. UV curing must be configured for the coating film weight and press speed. Contact Triwill Group’s technical team for press-specific application guidance.

Which UK suppliers offer high viscosity UV coatings for commercial printing?

Triwill Group supplies TWGU6400 and our complete UV coating range for commercial offset printing across the UK. We offer competitive bulk pricing and fast, reliable delivery. Contact our team for product specifications and technical guidance.

What are the health and safety guidelines for handling UV coatings in production?

UV coatings should be handled with appropriate PPE including nitrile gloves and eye protection as uncured UV coatings can be skin sensitisers. Avoid prolonged skin contact and ensure adequate pressroom ventilation. Follow COSHH regulations and refer to the product SDS for specific handling guidance for TWGU6400.

Can I order high viscosity UV coating in bulk from Triwill Group?

Yes, Triwill Group offers bulk ordering of TWGU6400 and our complete UV coating range. Competitive pricing and fast UK-wide delivery are available for commercial offset printing operations.
