Thomas Teflon conveyor belt adhesive |
|
|
Name High temperature resistant teflon adhesive (cures at room temperature)(THO4096-2) Outline It is heterocyclic adhesive which cures at room temperature. it is temperature resistant and easy to operate. No bubbles appear after curing thus making the surface smooth and bright. Applications Because the corrosion-resistant quality of the eteline or teflone, the materials are often used to make pipelines, vessels, bumps and valves. Our adhesive solve the problem of bonding or coating such materials themselves and to metals, alloys which may be used in high frequency communication devices and other devices which works in harsh conditions. These materials include PTFE, TFE, FEP, ETFE, CTFE, E-CTFE, PVF2, PVF, PP, PE and so forth. Features Component A is transparent liquid, Component B is viscous fluid. Its surface sets within 8 hours, and it reaches its maximum bonding strength within 36 hours. It is resistant to shock, ultraviolet light and extreme weather once it cures because it is durable and with good ductility and low contraction coefficient. Being heat-resistant, it adapts to a wide range of temperature and bonds well under high temperature. Being moderate in viscosity, the surface appears smooth and bright after curing. Apply the adhesive to the surface of the substrates directly or fill it into the gap, then heat it... You'll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes. Non-toxic after it cures and it is upto the RoHS standard. Shelf life is half a year. The main technical parameters are as follows: Temp. resistance scope:- 52 °C—+220 °C voltage withstand 20-25kV/mm hardness shore D60 at120°C, uniform tensile strength 50N/cm; right angle tensile strength: 45N/cm flush tensile strength, 42N/cm Instruction 1. To get the best results, it is better to sand the substrates several times in the clockwise and counterclockwise direction, and then immerse the eteline materials in the liquid “A” specially made by our company for 5 minutes, take them out, wash them clean in the running water, or for the best result, in the distilled water, dry them. Then cleanse the two bonding substrates with liquid “B”. wait till they are dry. bond them in time. 2. Mix A and B in a proportion of 3:1-5:2, stir the mixture well before using. 3. Spray the adhesive on the substrates, put them together and apply some strength on them. Notes 1. Better to keep the working place well ventilated. 2 .If it has contact with skin, you should wash with soap. 3. It can be stored at well-ventilated places with low temperature, and keep them away from fire. Cover the lip after using it. Copyright © 2005-2011 Thomas Technology, Inc. All Rights Reserved.

Name High temperature and moisture resistant adhesive(THO4095-II) Outline It is heterocyclic adhesive which cures fast when heated. it is temperature resistant and easy to operate. No bubbles appear after curing thus making the surface smooth and bright. Its viscosity and heat resistant property is adjustable. Applications It applies to the coating, infiltrating and encapsulating of device surface, electronic components and chips in electric engine, capacitor, thermocouples, transformers, rectifiers, electronic modules LSI and other products to protect them against moisture, chemicals, excessive heat, vibration, mechanical impact and thermal shocks. It also applies to the bonding of metals, alloy, ceramics, glass and transparent compound which work under water or in some humid environment. Features It is one-component transparent thick liquid. It cures within one minute when heated with the temperature 120 deg.C for one minute. It is resistant to shock, ultraviolet light and extreme weather once it cures because it is durable and with good ductility and low contraction coefficient. Being heat-resistant, it adapts to a wide range of temperature and bonds well under high temperature. Being moderate in viscosity, the surface appears smooth and bright after curing.

The main technical parameters are as follows: Temp. resistance scope:- 52 —+ 325deg.C volume resistance: 1.7×1015Ω.cm sheet resistance 2.5×1015Ω voltage withstand 28-35.5kV/mm hardness shore D85 dielectric coefficient:4.4 Tensile strength≥35MPa; bending strength≥65 Mpa compressive strength≥175MPa shearing strength≥28.8Mpa shock strength≥17KJ/m*m Instruction 1. To get the best results, the two surfaces being bonded should be free of oils, dirt, moisture and other contaminants and should be slightly roughed or sanded to remove gloss. 2. Spray the adhesive on the substrates, put them together and apply some strength on them, heat it with 120°C, wait for one minute and let it dry Notes 1. Better to keep the working place well ventilated. 2 .If it has contact with skin, you should wash with soap. 3.
