APPLICATIONS

JOINFLEX 126 Construction PU Sealant is used for bonding or sealing joints between most construction materials, where high or middle bond strength is required.

Trafficable floor joints

Assembly of metal framed buildings

Cover plates and covings

Bolted lap joints

Prisons, gaols, grand stands

 

APPLICATION LIMITS

JOINFLEX 126 Construction PU Sealant is not suitable for adapting to structural fitting and following situations:

1. To all surfaces that bleed oil, organic acid, alkali, plasticizers or solvents such as wood immersed in oil, oil crack filler, and some uncured or sulfurized fat and to surface where is wet;

2. To the substrate that the surface temperature exceeds +45°C or apply at temperatures below +5°C;

3. Use in the manufacturer of IG units;

4. To the surfaces that with direct touch of food.

5. Not recommended for use in below ground joints or trafficable

6. Joints where abrasion and physical abuse are encountered.

7. Not recommended for none of both surfaces is porous.

8. Avoid exposure to high level of chlorine.

9. Avoid contact with alcohol and other solvent cleaners during cure.

10. Do not apply when a moisture vapour transmission condition exists at time of application, as this can cause bubbling within the sealant

 

HOW TO USE

APPLICATION TEMPERATURE:   +5°C to +45°C

Cleanse with a cleaning agent, to keep the substrate surfaces completely clean(JOIN LEADER also provide the cleaning agent for your convenience).

Use the sealant after cleaning agent dries, around 1~2mins later. You can use two different cloth, one for cleaning agent, and the other for sealant. (Notice that the two can’t be mixed use together, and the second cloth will be better purified cotton and no picking.)

For better appearance, cover outside of joint areas with masking taps before application.

Cut nozzle to desired size and extrude sealant to joint areas.

Tool immediately after sealant application, make it smooth and remove masking tape before sealant skins.

 

SHELF LIFE

12 months in unopened packaging in a cool and dry storage place at temperatures between +5°C and 25°C.

 

COLOR
