Technical Information

CURE MECHANISM

The curing of Sikadur® Blade Repair Kit-90 takes place by chemical reaction of the two components. Higher temperatures speed up the curing process and lower slow it down.

CHEMICAL RESISTANCE

In case of chemical or thermal exposure conduct project related testing.

Application

Application Information

Surface Preparation

It is necessary to prepare the substrates prior to lamination to ensure optimal adhesion and strength. Surfaces must be clean, dry and free from grease, oil, dust and contaminants. After the cleaning process, a physical or chemical pretreatment might be required, depending on the surface and type of material.

Removal

Uncured Sikadur® Blade Repair Kit-90 may be removed from tools and equipment with Sika® Cleaner P. Once cured, the material can only be removed mechanically.

Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.

Do not use solvents on skin.

STORAGE CONDITIONS

Sikadur® Blade Repair Kit-90 has to be kept between 5 °C and 35 °C in a dry place. During transportation, a maximum temperature of 60 °C must not be exceeded. Do not expose to direct sunlight. If crystallisation of resin occurs, heat the MixPax up to 60 °C for 1 ─ 2 hours.
