S-LEC K(KW, KX)
Water-based Polyvinyl acetal resin
S-LEC K ( KW, KX )
Overview
Eco-friendly water-based polyvinyl acetal resin capable of improving adhesion and strength
- S-LEC (PVB) is composed of three units:acetal group, acetyl group and hydroxyl group.
- Soluble in water and alcohols and develop various functions such as adhesion and toughness.
- Can be used in a wide range of applications such as binders, dispersants and adhesives
Applications
- Primers / Adhesives
・Primer for plywood printing - Ink receiving layer
・For inkjet printing
・For dye-sublimation printing - Paints / Inks
・Water based coatings ( automobiles, etc.)
・Anticorrosion paints
・Water-based paints for printing
・Whiteboard inks
Material Properties
■Sheet Strength
Strength of resin film was measured by tensile tester.
■ Water resistance (S-LEC K KX)
Resin films were kept in various humid conditions.
■Antifogging property (S-LEC K KX)

Control of Material Properties
S-LEC KX and KW are water-based polyvinyl acetal resins obtained by adjusting the ratio of the three units that compose the resin to increase the polarity of the molecules. Because they exhibit a variety of chemical and physical properties, it allows us to propose suitable grades with properties that meet your needs.
