Description
Overview & Shop Floor Performance
Texsource ProCoat is a premium, pre-sensitized 1-part SBQ pure photopolymer emulsion designed specifically for textile screen printers demanding ultra-fast burn times, crisp edge definition, and dependable exposure latitude. Formulated with a balanced 41% solids content, ProCoat glides smoothly across mesh counts ranging from coarse athletic weaves to fine detail halftones—eliminating screen room bottlenecks and delivering sharp, repeatable print runs.
- Ready Straight from the Container: Pure photopolymer formulation requires no diazo mixing, deionized water, or settling period—extending shelf life up to 24 months (2 years).
- Extreme Exposure Speed: Blazes through exposures up to 4x to 8x faster than standard dual-cure emulsions, making it the ideal upgrade for LED exposure units and multi-screen production shops.
- High Humidity & Tack Resistance: Resists softening, peeling, and tackiness even in high-humidity shop environments, keeping stencils firm and easy to handle.
- Exceptional Detail & Resolution: Excellent edge bridging captures intricate fine lines, halftones, and four-color process separations with precision.
- Fast, Mesh-Safe Reclaiming: Breaks down quickly in washout booths using standard emulsion strippers without locking into polyester mesh fabrics.

Frequently Asked Questions & Troubleshooting
Q: What is the main difference between Texsource ProCoat and Texsource Tex-Blue?
A: Both are pure photopolymer SBQ emulsions that do not require mixing. ProCoat features a 41% solids content with balanced flow, making it ideal for standard textile printing and fine halftones. Tex-Blue features a higher 45% solids content, which yields a slightly thicker stencil build per coat for heavy ink deposits.
Q: Why are my fine halftones and line details closing up during exposure?
A: Overexposure or light scatter is the primary cause of stencil closing. Because ProCoat is highly light-sensitive, ensure your positive film has a true D-max opacity of 3.0+ and use an exposure calculator to prevent light undercut.
Q: Does ProCoat work with water-based or discharge inks?
A: ProCoat is primarily optimized for standard plastisol and UV inks. For high-volume water-based or discharge production runs, post-harden the dried stencil with an emulsion hardener, or consider a dedicated water-resistant dual-cure emulsion.
