Thermally Conductive Silicone Adhesive TSE3280-G

Transcription

1 Thermally Conductive Silicone Adhesive TSE38-G TSE38-G is a one-component, heat curable silicone adhesive designed for thermally conductive applications. The product adheres well to a variety of substrates, such as metals, plastics, ceramics and glass without the use of a primer. KEY FEATURES Excellent thermally conductivity Ready to use one component Heat accelerated cure Excellent adhesive properties; primerless adhesion to many types of substrates Non corrosive to metals APPLICATIONS Sealing and bonding for thermally conductive applications Heat generating elements, Regulators, Rectifier, Thyristor, etc TYPICAL PROPERTY DATA (JIS K 649) UNCURED PROPERTIES Appearance Flowable paste, Gray Viscosity (3 C) Pa s {P} 6 {6} CURED PROPERTIES ( 5 C) Appearance Elastic rubber, Gray Density (3 C) g/cm 3.3 Hardness (Type A) 6 Tensile strength MPa {kgf/cm } 3. {33} Elongation % Adhesive strength * MPa {kgf/cm }. {} Linear expansion * /K.5-4 Thermal conductivity W/(m K) {cal/(s cm C)}.88 {. -3 } Volume resistivity Ω cm.5 4 Dielectric strength kv/mm Dielectric constant (6Hz) 4.3 Dielectric loss (6Hz). *: Aluminum lap shear *: In-house test method Typical property data values should not be used as specifications. /5

2 CURE TIME VS. TEMPERATURE Actual cure time will depend on the type and efficiency of the oven used, and the shape and heat capacity of the parts and containers. A sample test should be conducted to determine the appropriate cure time. Typical cure times and temperatures are as follows. TEMPERATURE CURE TIME C h ADHESION CAPABILITY Suitable substrates Metal: Aluminum, Copper, Ni plated, Stainless Steel Plastics: PPS, PBT, Epoxy resin, Polyester, Phenolic resin Rubber: Heat cured silicone rubber Inorganics: Glass, Ceramics Unsuitable substrates Plastics: PP, PE, Fluorocarbon resin Rubber: RTV silicone rubber, Sulfur vulcanized rubber, Fluorocarbon rubber ADHESION STRENGTH VS.

5 HANDLING AND SAFETY Materials such as water, sulfur, nitrogen compounds, organic metallic salts, phosphorus compounds, etc. contained in the surface of the substrate can inhibit curing. A sample patch should always be conducted before proceeding to determine compatibility. All parts should be as clean and dry as possible prior to application. Wear eye protection and protective gloves as required when working with this product. Maintain adequate ventilation in the work place at all times. STORAGE Store in a refrigerator (- C) to prevent viscosity increase. When returning to room temperature, allow the contents to return to room temperature before opening the container to avoid condensation. Keep out of the reach of children.
