Silicone Sealing Materials for Construction

Silicone Oil

Silicone Oil is generally a clear, colorless liquid with excellent resistance to heat, cold, and water. They have excellent resistance to heat, cold and water. They also show little change in viscosity over a wide temperature range and have excellent electrical properties. In addition, silicone oil has mold-releasing properties, water repellency, antifoaming properties and lubricating properties.

 Product Features

● Heat Resitance

It has excellent stability against thermal oxidation.

● Cold Resitance

Excellent resistance to cold; low-temperature methylphenyl silicone oil remains fluid even at -65°C.

● Viscosity Stability

Little change in viscosity over a wide temperature range, from low to high temperatures.

● Chemical Stability

Extremely chemically inert. At room temperature, it is virtually unaffected by alkaline solutions of less than 10% and acid solutions of less than 30%.

● Non-Corrosiveness / Influence on Other Materials

It has almost no adverse effect on metals and many other materials.

● Low Serface Tension

It exhibits extremely low surface tension values compared to water and ordinary synthetic oils.

 Main Products

Silicone Resin

Silicone resin is a resin composed of a three-dimensional mesh structure and is used as a resin material in most cases. Their films have numerous properties such as heat resistance, weather resistance, electrical insulation and water repellency. In addition, they are available in a variety of properties from highly viscous liquids to solids, and are useful for improving durability, safety and reliability in a wide range of fields, especially in paints, coatings and electrical applications.

 Properties when used as a Resin Material

● Heat Resistance

Withstands heat up to 250°C.

● Weather Resitance

Excellent UV resistance.

● High Hardness

Forms a high-hardness film due to its three-dimensional mesh structure.

● Water Repellency

Forms a film with good water repellency, especially for products containing methyl groups.

● Electrical Insulation

Excellent electrical properties over a wide temperature range.

 Main Products

One-Component Liquid Rubber (RTV Rubber)

One-component liquid silicone rubber can be worked by simply pushing it out of a container such as a tube or cartridge, and after curing, it becomes a rubber elastic material. It is used in a variety of applications because of its ability to adhere well to almost any material upon curing.

 Features

● Electrical Characteristics

Excellent electrical characteristics such as voltage resistance and resistance value

● Heat and Cold Resistance

Can be used in a wide range of temperatures from -40°C to +180°C.

● Shock Resitance

After rubber curing, it absorbs vibration and shock with its excellent rubber elasticity.

● Weather Resistance

Excellent resistance to ultraviolet rays, ozone and water, so it hardly deteriorates even when exposed to wind and rain for a long time outdoors.

● Workability

Since the product is filled in a tube or other containers, it can be easily worked by simply pushing it out.

LIMS (Liquid Silicone Rubber Injection Molding System)

LIMS (Liquid Injection Molding System) is a molding process system that combines liquid silicone rubber, which has excellent properties, with a molding machine that precisely and stably injects it. The entire process from mixing to molding can be automated, simplifying and shortening the process while facilitating the molding of high-quality products.

 Features

● Shorter Process

Since liquid silicone rubber is cured by an addition reaction, the curing speed is fast and the molding time can be shortened.

● Improved Productivity

Since the material is in liquid form, it can be molded at low injection pressure. It is also suitable for molding precision parts.

● Automation of Molding

Applicable to burr-free and runnerless molding. In addition, it has excellent mold-release properties after curing, making it possible to automate the molding process.

● Environmental Consideration

No byproducts from curing reactions. Burr-free and runnerless molding eliminates the need to dispose of waste materials, enabling environmentally friendly manufacturing.

Grease and Oil Compounds

Silicone grease is a product made by blending a base oil of silicone fluid with various additives and thickening agents such as metallic soap. They have excellent thermal oxidation stability and water resistance over a wide temperature range, and are mainly used for lubrication.                                                                               Silicone fluid compounds are grease-like products made by blending silicone fluid as a base oil with silica fine powder and other additives. They have excellent thermal oxidation stability, electrical properties, and water repellency over a wide temperature range, and are used for electrical insulation, sealing, heat dissipation, water repellency, and other purposes.

 Features

● Heat and Cold Resistance

The Silicone oil has excellent heat and cold resistance, high drop point, low oil release and low volatile content as a base oil.

● Water Resistance

It is resistant to moisture and humidity. In the case of silicone greases, even if they are left in water for a long time, the surface only turns white and there is almost no internal change.

● Safety

The silicone oil is chemically inert, making it extremely safe for living organisms as a base oil.

● Efficiency

A small amount is all that is needed to achieve excellent performance.

 Main Compounds

Does not cause stress cracks in plastics. Good steel-to-steel lubricity
