It is easy and convenient to use for it cures at room temperature and bonds well. No bubbles appear after curing thus making the surface smooth and bright. Its liquidity, color and heat-resistance quality are adjustable Applications It applies to the encapsulating electronic components, chips and cable wires to protect them against moisture, chemicals, excessive heat, vibration, mechanical impact and thermal shocks. Features Component A is pasty, non-solid particle. component B is in tinted paste shape. Fast curing velocity. At 25 °C, within 1-3 hours, its surface cures, 18 hours later, it reaches its maximum bonding strength. Being durable and resistant to ultraviolet light once the bond has formed. Being heat-resistant, it adapts to a wide range of temperature and bonds well under high temperature. Mix the two components in a certain proportion, apply it to the surface of the substrates directly, which makes it so convenient to use. You'll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes. Non-toxic after solidification, though it is a little smelly. Shelf life is one and a half year. The main technical parameters are as follows: Heat resistance scope：- 52 °C—+ 250 °C volume resistance: 1×1015Ω.cm sheet resistance 2.5×1015Ω voltage withstand 20-25kV/mm hardness shore D68 Water absorbing capacity 24h＜0.1% Tg:250℃ contraction coefficient 1.5 Tensile strength≥25MPa; Shearing strength≥20 MPa Instruction 1. Clean the surface of the material, make sure they have no dust or oil on them, wait until they are dry. 2. Mix A and B in a proportion of10：1-1.25 and apply it evenly on the substrates. 3. Spread the mixture on the substrates, put them together and apply some strength on them, finally, let them dry for 2-4 hours Notes 1. The tools used to get adhesives should be different. 2. It is necessary to keep it well ventilated and away from fire. 3. If it has contact with skin, you should wash with soap. 4. It can be stored at well-ventilated places with low temperature, and keep them away from fire. Cover the lip after using it. Copyright © 2005-2010 Thomas Technology, Inc. All Rights Reserved.
