50g Bondloc Steel-Reinforced Repair Epoxy Putty Stick

Our 50g Bondloc Steel-Reinforced Repair Epoxy Putty Stick is a hand kneadable, speciality epoxy putty that mixes in 1 minute for permanent repairs to many substrates. This putty contains a fading black dye that becomes grey after mixing.

It may be applied underwater (fresh or salt), and bonds to: fibreglass, metal, wood, concrete and glass. This type of putty will not yellow with exposure to UV, and hardens in 10 minutes, back in service in an hour, with it becoming full strength in 24 hours.

Applications uses

This adhesive putty is ideal for the following uses:

• Steel
• Repairing tanks and drums
• Patching holes in pipes
• Stopping leaks
• Repairing porosity holes in castings

Instructions for use

Proper surface preparation is essential to a successful application. The following procedures should be considered:

Degrease the surface, oil, grease and dirt must be removed before applying any epoxy material.

All surfaces must be thoroughly roughened ideally by grit blasting (8-40 mesh grit), or by grinding with a coarse wheel or abrasive disc pad. An abrasive disc may be used provided white metal is revealed. This creates an increased surface area for better adhesion. A 3-5 mil profile is desired for an application.

Do not “feather edge” epoxy materials. Epoxy materials must be “locked up” by defined edges and a good 3-5 mil profile.

Metal that has been handling seawater or other salt solutions should be grit blasted and high-pressure water blasted and left overnight to allow any salts in the metal to “sweat” to the surface: repeat blasting to “sweat out” all the soluble salts.

A test for chloride contamination should be performed prior to any epoxy application.

The maximum soluble salts left on the substrate should be no more than 40p.p.m (parts per million).

Under cold working conditions, heating the repair area to 38C – 43C immediately before applying is recommended. This procedure dries off any moisture, contamination or solvents and assists the epoxy in achieving maximum adhesion to the substrate.

All prepared surfaces should be repaired as soon as possible, to eliminate any changes or surface contaminants.

This epoxy is very good in water, saturated salt solutions, leaded gasoline, mineral spirits, ASTM # 3 oil and propylene glycol.

However, please note this product is generally not recommended for long term exposure to concentrated acids and organic solvents.

For immersion applications this product is not recommended.

Twist or cut off the required amount from stick. Then knead with fingers to a uniform colour. All black colour dye must be gone and uniform pure grey colour is left. Apply to surface to be repaired within 2 minutes of mixing. The mixed epoxy does not show much bond strength at this time but can be kneaded or formed into any cracks or holes to be filled. Once set this can then be sanded and painted as required.
