Metal Repair

A controlled structural repair system for rigid metal. Mix true 1:1, build it past the damage, clamp it — takes load in 24 hours.

01The compound

XE-S300-1 is a two-part structural epoxy. Resin and hardener mix in a true 1:1 ratio — blended to one uniform color, no streaks — and cure into a hard, waterproof body.

1:1 — one uniform color, no streaks

Working time

Up to 30 minutesAt 77°F (25°C). The clock starts when mixing starts.

Initial set

3–4 hoursClamp through the set. Don’t touch it while it sets.

After 24 hoursNothing gets loaded before 24 hours.

Hardness, fully cured

Shore D 85–90

03The method

The method is the product.

1 · PREPARE

Clean, dry, sanded — in that order.

2 · PURGE

Purge the cartridge until both sides flow even.

3 · MIX — TRUE 1:1

One uniform color, no streaks.

4 · BUILD

Build past the damage — extend 0.5–1″ beyond every edge. 1/16–1/8″ thick for small repairs; 1/8–1/4″ for load-bearing.

5 · ALIGN

Set the parts in position.

6 · CLAMP

Clamp it through the set. Bring your own clamp.

7 · CURE

Hands off for 3–4 hours. No load before 24 hours.

04Honest limits

The repair won’t be invisible — but once cured, it takes load.

Not for polyethylene (PE), polypropylene (PP), PTFE, silicone, soft or flexible parts, fuel and brake lines, exhaust manifolds, or pressure-critical and safety-critical repairs. If it is safety-critical, replace the part — don’t bond it.

05Longevity

“Fix it tonight. Back to work tomorrow.”

Questions

How long until I can use the part?+

Up to 30 minutes working time, 3–4 hours initial set, and 24 hours before the repair takes load.

Can I drill, sand, or paint it after curing?+

Yes — after 24 hours the cured body machines like metal. Drill it, sand it, paint it.

Do I need a glue gun?+

No. A push rod is in the box and does the job. An AB glue gun is optional.

What if the repair fails?+

Follow the method card — if the repair fails within 30 days of delivery, you choose a full refund or a free replacement box. How to claim →
