Fast-Dry Universal Ink Receptive Boehmite
Catalog No.: JYS-4535 CAS: 1318-23-6 EINECS: 215-284-3
Solution grade for packaging substrates and scalable production efficiency
Best Fit For
Packaging substrate producers and coating system integrators who need reliable fast drying on multiple paper/board grades, stable color density, and strong coating adhesion and converting robustness.
What We’re Solving
• Slow drying → set-off, blocking, line speed limitation
• Cracking or wrinkling during converting
• Unstable color density across different paper grades
• Frequent formula tuning during scale-up
KPI Targets
• Fast dry time for high-speed production
• Stable Color Density and color consistency
• Strong adhesion / no powdering / anti-cracking
• Excellent wrinkle resistance in post-processing
Coating-System / Mechanism
JYS-4535 is universal-grade boehmite designed for packaging paper systems. Good pore volume and ink holding support balanced density and stability; strong coating adhesion supports converting reliability; wide formulation window simplifies scale-up and adjustment.
Recommended Applications
• Coated art paper for packaging and commercial print
• Fast-dry inkjet and label papers
• White coated paperboard (WLC / coated duplex board) and specialty papers
Engineering Notes
• Designed to help integrators run one grade across multiple substrates
• Works well in packaging inkjet coatings that require adhesion and flexibility
• Available as ready-to-coat ink-receptive slurry on request
Recommended Use Range
• Recommended solid content in coating: 6–22% (system-dependent)
• Typical addition level: 15–50% of pigment portion
• Target coating weight: 5–15 g/m² for packaging paper/board and label stocks
• Designed for wider formulation window and easier scale-up.
Note: values are for reference only and should be validated per substrate/ink system.
Typical Coating Layer Role

Proof & Typical Results
Typical improvement directions
In packaging inkjet coating systems, JYS-4535 is commonly linked to:
• faster drying and improved runnability
• more consistent Color Density across paper and board grades
• stronger coating adhesion and reduced converting defects (wrinkle/crack tendency, set-off, powdering risk)
How customers validate
Packaging substrate teams often validate via:
• production line dry time / set-off testing
• adhesion and coating integrity tests (tape/rub/fold)
• blocking resistance under stacking
• print consistency checks across multiple substrate lots
Optimization notes
This grade is designed for scale-up:
• used to standardize coating systems across multiple substrates
• supports “one-grade” production strategy with a wide formulation window
• slurry option can reduce dispersion variability and improve consistency in large-scale operations
