Name

Thomas moisture resistant structural adhesive    (THO511-2)

Outline

It is a high-gloss two-component modified resin structural adhesive.it cures at room temperature or when heated.It is resistant to temperature shocks and with good resilience. The most distinguishing feature is that the adhesive remains pliable and tough after the bonding formed.

Applications

It is applied to the bonding of polystyrene, PVC, ABS, PET, Kevlar,silicone rubber, polyurethane etc. It also used to bond ceramics and metals.

Features

Part A is sticky liquid with light color. B is sticky and colorless liquid.

Curing time: at the temperature of 25 degC, the maximum bonding strength is reached within two and a half days; If it is heated at the temperature of 80 degC, the good bonding strength will be reached within 8 hours.

Being weather and 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 acquiring no strict treatment, which makes it so convenient to use.

You’ll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes.

if long-term exposed to the atmosphere, surface and the performance of its fundamental unchanged

Being stable, its storage time is one and half a year.

The main technical parameters are as follows:

Heat resistance scope：- 70°C－+ 220°C

peel strength ≥29kn/m  Shearing strength≥28.5MPa

Water Absorption 100℃，RH100% ，0.01%

(3000hours later) tensile strength 35MPa, pressing strength 175MPa

Impact ductility 17KJ/m*m surface resistivity 2.5×1015Ω  volume resistivity 251×1015Ω.cm  voltage resistivity 20-25kV/mm

shearing strength≥26.8MPa(25°C) 13.4MPa(200°C)  hardness D65

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 at a proportion of 3:1-1.2, mix them well.

3. Apply the mixture on the substrates evenly. Put them together together and apply some strength.

Notes

1. temperature influences the curing time, the higher the temperature is, the faster the curing time will be. But heating temperature shouldn’t be higher than 110 deg C.

2. Use another can or container to blend A with B. The tools used to get A and B should be different.

3 Aand B should be mixed well.

4 It is necessary to keep it well ventilated and away from fire.

5 If it has contact with skin, you should wash thoroughly with soap and water.

6 It can be stored at well-ventilated places with low temperature, and keep them away from fire.

7 Cover the lip after using it.
