Resins for Polyurethane Dispersions, Reactive Polyurethane Adhesives and Solvent-based Polyurethane for Textiles and Leather

Sun Chemical and its parent company, DIC Corporation, manufacture resins for a variety of textile and leather applications.

Polyurethane Dispersions

DIC offers a wide range of polyurethane dispersions like binders, primers, adhesives, coatings. These can be used in sophisticated applications such as artificial leather, textiles, automotive, aircraft, flexible films, optical films, metal pre-treatment, and sizing agents.

Key attributes and features:

• Environmentally friendly, bio-based grades are available
• Excellent adhesion to various substrates
• Superior texture, abrasion resistance and flexibility properties
• Food contact compliant primer grades
• Non-yellowing, high durability and breathability
• Excellent workability in various fiber processing

DIC’s HYDRAN WL Series are PUDs designed for production of artificial leather and feature skin layer, adhesion and coagulation grades.

DIC’s HYDRAN AP Series are primers and coatings for various kinds of flexible plastic films.

DIC’s HYDRAN CP Series are used as chromate free metal pretreatments.

DIC’s VONDIC are especially suitable for glass and carbon fiber sizing applications.

Reactive PU Hot Melt Adhesive

DIC’s reactive polyurethane hot melt adhesives are used in automotive, wood, textile, shoe, and other industrial applications.

Key attributes and features:

• Optimized for numerous textile applications
• Superior penetration of textile fibers
• Exceptionally rapid bond strength
• Best-in-class bond strength for faster line speeds

DIC’s TYFORCE more easily penetrates textile fibers and quickly builds bond strength. Additionally, TYFORCE exhibits outstanding flexibility and allows for exceptionally fast line speeds.

Solventborne PU for Synthetic Leather Applications

DIC solventborne PU are well used in synthetic leather for furniture, hospitality, automotive, clothing and aerospace application

Key attributes and features:

• Optimized for artificial leather applications
• Industry-leading abrasion resistance
• Exceptional light resistance
• Provides improved flexibility and texture

DIC’s CRISVON resins offer artificial leather surface coatings with improved abrasion resistance, light resistance, and flexibility. CRISVON abrasion-resistant resins improve texture as needed.
