Usage Examples

Silaplane™ is a reactive polydimethylsiloxane (PDMS) having reactive functional groups at one or both ends of the linear siloxane chain.

Usage Examples of Silaplane™

01 — Synthesis of Silicone Modified Polyurethane Resin

FM-DA series, since it has hydroxy groups, can form urethane bonds by reacting with various isocyanates.

Reaction Example:

FM-DA26 — Reaction example showing the synthesis of a silicone-modified polyurethane resin using Silaplane™ (サイラプレーン®).Silaplane™ (サイラプレーン®) is a reactive silicone macromonomer; adding a small amount (1–5% )of it during resin formation imparts water repellency, stain resistance, slip properties, and durability to the resin. Silaplane™ (サイラプレーン®) can be applied to coating agents, synthetic leather, and resins for building materials.

Imparted Characteristics:

Slip Properties
Abrasion Resistance
Water/ Oil Repellency

Application Example:
Artificial Leather

02 — Synthesis of Silicone Modified Acrylic Resin

FM-07 series can be polymerized with various vinyl monomers since it has a methacryloxy group.

Reaction Example:

This is an example of a reaction for synthesizing silicone-modified acrylic resin using Silaplane™ (サイラプレーン®)FM-0721. By adding a small amount (0.2-5%) of Silaplane™ (サイラプレーン®)during resin modification, silicone properties such as water repellency, stain resistance, and slip resistance can be imparted to the resin, resulting in surface modification effects. Silaplane™(サイラプレーン®) is used in paints, coatings, and functional surface treatment materials.

Imparted Characteristics:

Slip Properties
Antifouling Properties
Water/ Oil Repellency

Silicone modified acrylic resin has water and oil repellency and can be used as an alternative to PFAS.

03 — Use of Silaplane™（Silicone） as filler dispersant

When used as a filler dispersant, FM-04/0815J has the effect of lowering the viscosity of filler dispersion liquids and improving the filler filling rate.
