RMS K1-40 800L

K1-40 is a rapid breaking cationic bitumen emulsion designed to be used as a cold applied tack coat classified according to BS EN 13808:2013 as Bitumen Emulsion C40B3.

K1-40 are cold applied, liquid bitumen emulsions, used in the construction and repair of pavements, driveways, roads, and highways

K1-40 should be spray-applied, following the guidance and rates of spread advised in BS 594987. The emulsion film should be allowed to fully break (turn black) before the overlay is applied.

Dispensing taps also available for 200L Drums:   3/4" Brass Tap

Where to use

K1-40 is primarily used as a tack coat, to provide a bond between the existing surface
and overlays e.g hot rolled asphalt, macadam and slurry seals, or between courses in road construction.

It serves two purposes in this instance:-
1. Minimizing the risk of spillage between the two courses.
2. Ensuring that during laying of the new overlay, pushing and sliding are reduced, resulting in improved compaction.

K1-40 is also used in mist spraying and concrete curing operations.

Coverage

200KG  | 60M2 - 100M2

k1-40 can be used at the ambient temperature at the spray rate of 0.25 to 0.70 litre per square meter (0.05 to 0.15 gallon per square yard).

This grade must only be applied in dry, frost-free conditions which will remain throughout the film drying period. Temperatures of between 5°C and 35°C should prevail.

Before application drums should be well rolled to agitate contents before use. Cationic emulsions should be applied by brushing with hand broom or squeegee. Spread in one direction only and avoid scrubbing often. It is more practical to apply by spray as this provides a uniform distribution and even film. Spray equipment should conform to BS3136: Specification for Cold Emulsion Spraying Machines for Roads.
Spray evenly to avoid ponding in hollows as this may cause localized “fatting up” of the subsequent courses.
