1807-1

DESCRIPTION:

1807-1 adhesive is a high strength, two component, Epoxy Resin system designed primarily for core bonding and composite to composite bonding of large laminates. It is ideally suited for the bonding of main load bearing structures in Wind Turbine Blade assembly. It is available in different curing speeds allowing processing over a large range of ambient temperatures.

APPERANCE:

 1807-1- AB (Epoxy Resin)

Density at 20 0c (ISO 1675)         1.40– 1.45 g/cm3

Flash Point (ISO 2719)                 > 120 0c

1807-1A-AHA / 1807-1B-AHA (Adhesive Hardener)

Density at 20 0c (ISO 1675)         0.9– 1.00g/cm3

Flash Point (ISO 2719)                 > 120 0c

APPLICATION DATA:    Mixing

                                Mixing Ratio by weight      100 Parts 1807-1 resin to 35±3 Parts 1807-1 hardener

                                Mixing Ratio by Volume     100 Parts 1807-1 resin to 48±3 Parts 1807-1 hardener

The components should be mechanically mixed thoroughly at medium speed ensuring that no unnecessary air is entrained. Both sides and bottom of container should be scraped during mixing process.

Suggest using the mixing machine to mix the resin and hardener, which can avoid the generation of microbubble efficiently and make the properties of material into full play. The manufacturers of mixing machine are as follows: 2KM,Dekumed, Graco, Dopag/Huk and so on.
