Matsui

Matsui Silicone SI0326 Ink Catalyst is a required crosslinking additive designed specifically for use with Matsui Yama Series Silicone Inks. This catalyst activates the silicone ink system, enabling proper curing, durability, stretch performance, and wash resistance when printing on performance apparel and technical fabrics.

SI0326 allows screen printers to control pot life and curing behavior, making it ideal for professional production environments printing athleticwear, compression garments, swimwear, and premium stretch fabrics. Once added, the catalyst initiates the chemical crosslinking process that gives silicone prints their signature elasticity, abrasion resistance, and long-term durability.

⚠️ Note: Matsui Yama Silicone Inks are not pre-catalyzed. SI0326 must be added before printing.

Technical Specifications

Technical Specifications – Matsui Yama Silicone Catalyst

Product Purpose

Catalyst for curing Matsui Yama Silicone Ink System; enables crosslinking, durability, stretch, and wash fastness.

Mixing Instructions

Stir silicone base thoroughly before adding catalyst
Mix 90% silicone base + 10% catalyst (by weight)
Mix until completely smooth and uniform
Add pigments after catalyst if tinting is required
Allow mixture to rest 5–10 minutes to release air bubbles
Only mix what will be used within the 4–6 hour pot life

Screen Setup

Component	Recommendation
Mesh	80–160 (31–63T) depending on opacity and detail
Squeegee	70–80 durometer or triple-durometer blade
Stencil	Solvent-resistant emulsion

Printing

Print 1–2 strokes per layer
Flash between layers if needed
- Flash temp: ~220°F (104°C)
- Flash time: 5–8 seconds
For polyester or migrating fabrics, print over a silicone blocker base

Curing

Step	Setting
Cure Temp	300–320°F (150–160°C)
Dwell Time	1–2 minutes depending on dryer
Ink Film Temperature	Must exceed 250°F (121°C)

Full cure is required for maximum stretch, adhesion, and wash resistance.

Clean-Up

Use silicone-compatible ink cleaner
Avoid unapproved solvents — they may alter ink chemistry

Best Practices

✅ Keep screens flooded to prevent drying
✅ Pre-test on performance/elastic fabrics
✅ Store at 65–77°F (18–25°C); keep container sealed
✅ Label mixed ink with time to track pot life

❌ Do not mix with non-silicone ink systems
❌ Do not over-catalyze — reduces pot-life and may cause defects

Product Properties

Property	Value
Mix Ratio	90% base : 10% catalyst
Pot Life	4–6 hours after mixing
Flash Temp	~220°F (104°C)
Cure Temp	300–320°F (150–160°C)
Mesh	80–160 (31–63T)
Squeegee	70–80 durometer
Storage	65–77°F sealed
Shelf Life	12 months unopened
System	Matsui Yama Silicone Ink System
