Product description:
BD811 high strength structural adhesive is consist of high performance modified toughening resin and so on.
It can effectively achieve the connection between the same materials and dissimilar materials,partial replace riveting,
welding,threaded connections and other traditional process.

Performance features of BD811 high strength bonding repair epoxy compound structural adhesive:
1.The stress distribution is uniform
2.don’t need to heat,without heat effect and thermal deformation to the parts.
3.With the high bonding strength, partial can replace riveting, welding and other process.
4.Can achieve the connection along different materials.

How to use:
1.Surface treatment: Grinding or sand blasting to clean up the dust,greasy dirt and rust on the surface of adherend,
clean it by cleaning agent(can use Anhydrous alcohol acetone, ethyl acetate, etc) and dry it by airing in the end.

2.Configure adhesive: Make A and B two component mix uniformly according to specified requirements,
the mass ratio A:B=4:1

3.Using adhesive: Make the configured adhesives spread coating on the pending-bonding surface uniformly,
then fold it and compress it to be compacted,avoid getting into the air in the middle.

4.Curing:Initial curing for 4 hours at the room temperature,fully curing for 48 hours.
When the temperature is below  15℃,need to heat it up to the temperature of 80℃ and keep this temperature
for 2 hours after initial curing,then do the last curing,in this way,can get higher combination property.

Packaging specification:
Two-component,250g/set,8 sets/carton or 16 sets/carton

Storage:
This product is general chemicals,should pay attention to waterproof and fire prevention during transportation
and storage, save it in a cool and dry place,the storage period is 12 months.
