Matsui

Matsui SI0331 Yama Super White is an ultra-high opacity silicone ink designed for bold, brilliant whites on even the most challenging performance fabrics. Built for athleticwear, team sports, compression garments, swimwear, and premium retail apparel, Yama Super White delivers superior coverage, stretch, and durability on polyester, nylon, and spandex blends.

This advanced silicone system produces a smooth, bright white finish with excellent elasticity and rebound — ensuring prints maintain flexibility without cracking or fading, even under heavy stretch and high-intensity wear. Yama Super White can be used as a stand-alone white or as a powerhouse underbase to drive maximum color vibrancy in the Yama silicone ink system.

Engineered for high-end production, this ink cures quickly, resists dye migration, and maintains long-term wash performance, making it the go-to silicone white for elite apparel printers.

Mixing Instructions

Stir base thoroughly before use
Add 10% Matsui Silicone Catalyst (90% ink : 10% catalyst)
Mix thoroughly until smooth and uniform
Allow mixture to rest 5–10 minutes to release air bubbles
Only mix what will be printed within pot-life window

Printing Guidelines

Print 1–2 strokes for ideal coverage
Flash between layers as needed (~220°F / 5–8 sec)
Keep screens flooded to prevent ink build-up
For high-bleed synthetic fabrics, use a silicone blocker base

Curing Requirements

Cure at 300–320°F (150–160°C)
Ensure ink film reaches >250°F (121°C) for full cure
Always confirm cure with:
- Stretch test
- Wash test
- Temperature probe on ink film

Silicone inks reflect heat — slow belt speed or slightly raise dryer temp when needed.

Best Practices

✅ Use blocker base on bleed-prone fabrics
✅ Allow proper dwell for complete cure
✅ Test fabric & cure settings before production
✅ Maintain clean, consistent squeegee pressure

❌ Do not mix with non-silicone ink systems
❌ Do not over-catalyze (reduces pot-life and performance)
