This product is mainly used to repair and seal external cracks and defects of automobile and ship cylinder block, all kinds of metal shell and water tanks. It can cure at room temperature or heat cure. The adhesion strength is high in room and medium temperature. The cured material is with high hardness and it can work for long time from 150°C to 250°C.

Conventional performance:

Instructions and procedures:

In cold weathers or conditions, automobile, motorcycle and ship cylinder blocks sometimes would be frost crack or broken in some parts. It’s very uneconomical to replace a new cylinder block. There would have extended crack or leakage welding if use traditional welding method to repair, and it needs very professional welder. Forsen cylinder block repairing agent adhesive uses FEITIAN type technology. It’s easy to operate and economical. It can repair cylinder block quickly.

Bonding process:

1. Clean the cylinder block defective or frost-cracked parts, then find out the crack end and make the crack arresting hole.
2. Process the crack into V groove in order to fill adhesive.
3. Use hardware tools, grinding wheel or sandcloth to grind the surface flat.
4. Use cleaning agent to clean the glued surface until the surface has no stain and rust.
5. Group A and group B volume ratio should be 2:1 and well mixed. Surface to be repaired should be glued with enough adhesive both two sides.
6. After gluing, use tools to knock on the surface slightly to make the adhesives bond crack fully.
7. Strengthening treatment by iron plates or copper plates if crack or damages are serious. Strengthening treatment by fiberglass cloth if crack or damages are not serious.

① Strengthening treatment by fiberglass cloth: use 2 layers or 3 layers fiberglass cloth. Bond the fiberglass cloth from small to large. Every layer shall be soaked with enough adhesive for better bonding strength.
② Strengthening treatment by iron plates or copper plates: plates thickness should be 5mm to 8mm. Plates surface shall be flat and clean, contact cylinder block tightly and fix the plates with cylinder block by screws.

8. 24 hours after bonding, the cured adhesive strength can reach 60%-70% at 20℃-25℃. If heat to 80℃, the cured adhesive will reach to maximum strength. It can also reach to maximum strength without heat treatment if cylinder block works in high temperature condition.
