Introduction
Darbond 3495 is two component, room temperature curing epoxy adhesive. Pour mixed material into cavities between wear-resistant liners and support structure to achieve no gap filling and bonding; Cured material can strongly support the cone and liner, for high impact and shock resistance. It is
Convenient and fast to use, with long working period and high efficiency.
T ypical Application
Used for China made PY series cone crusher and cone/gyratory crusher (such as Nordberg, Sandvik), filling the gap between liner and cone; Also can be used for equipment stand leveling. Mainly used for mining and smelting, hydro-plant, road building and building material industries. It also can be used for building, landscape stones, concrete and steel structure
Bonding and metal railing imbedding etc.

Directions for Use
Cleaning and Preparation: Remove the remained filling
Materials and rust in cone and liner. Assemble cone and liner.
Keep the cone and liner at 10-28, preheat or cool under
Safe conditions. Before operation, store 3495 A and B
Component at temperature 15-26. It' s recommended to use
Electric blender and high shear disc type mixing propeller
Below800rpm, and complete other pouring preparation.
Mixing: Open A component container, stir A component with
Electric blender up and down for about1 minute. Shake B
Component thoroughly and evenly. Add B component in
While stirring A component. Stir up and down for2-3 minutes
To achieveuniform color.
Pouring: After mixing evenly, pour immediately. Pour at one
Place and allow backing material to fill the cavity and push
Out the air in front of it. Use dam (tin, cardboard or clay, etc. )
To direct the flow when necessary, until full. Unmixed resin
(different color clinging to the sides and bottom) should not
Be drained into the crusher. For one package 3495, the time
From mixing to pouring should not beover10 minutes.
Curing: Keep cure temperatureof15-26.
Note: The lower temperature, the longer pot life, but higher
Viscosity (hard to pour). In case low temperature is below
10, it is recommended to raise the temperature of epoxy,
Liner and cone to 10-25 before work. In case the
Environment temperature is higher than 28, the pot life is
Shorter, shorten working time or reduce mixing quantity.
Another way is to use one package material for many times.
Cautions
Keep out of reach of children.
Operator should wear gloves.
It is recommended to use at well ventilated place.
In case of contact with skin, wipe away, then rinse with clean
Water immediately; In case of contact with skin, rinse with
Clean water immediately; If symptom goes on, call a physical
Attention.
