JM - 98 epoxy putty

JM - 98 epoxy putty

JM - 98 epoxy putty is based on epoxy putty to join thixotropic agent, filler, flame retardants, treating agent, curing agent and so on, at the beginning of viscous force is strong, not sag, hard and have a flexible adhesive solution after curing, mainly suitable for LPG and LNG ship gas cylinder saddle filling glue or move with the supporting frame.

(3) the construction process:

1. Before pouring construction should be liquefied gas cushion layer of contact surface is clean, remove grease, oil, water, mottled rust and paint, etc., and during construction shall be maintained without grinding, welding and pollute the environment.

2. The last must use solvent (acetone) to wipe clean gas cylinder saddle.

3. Will need A and B two components epoxy putty lid open, ready to stir.

A, play

1. The JM - 98 epoxy putty B component in A component.

2. The material must be even at low speed, to achieve the same color A, B two components.

Second, the casting

1. According to the requirements of the stamper thickness plus a certain margin (about 10 mm), starting from the lower slope upward to perfusion, must achieve irrigation.

2. The stamp is according to the thickness of each point, use ruler to measure, can reach the requirements before put the pot, put on both sides should reach tank after tank can go out of be bored with child.

3. A small amount of saddle groove in 20 mm, in the case of guarantee saddle bottom perfectly, on both sides of the casting is allowed.

4. JM - 98 epoxy putty best thickness 25 to 40 mm, maximum thickness must not exceed 50 mm, otherwise it will affect the construction.

Three, the construction time

When the ambient temperature of 25 to 30 ℃, the construction time is 1.5 hours or less.

Four, curing conditions

Environmental temperature 25 ℃ or higher (96 hours) and cole hardness of 30 or more.

Five, the matters needing attention

1. Ambient temperature is too high, application of volatile solvent for cooling.

2. Epoxy putty and tank should saddle
