(MFD, TO IS: 3384-1986)
TIKI PRIMER OB is a liquid bitumen of low viscosity which penetrates into a prepared surface upon application. It is commonly used for priming concrete and masonry surfaces prior to the application of the first mopping coat of melted bitumen in laying built-up roofings or membrane waterproofing, so as to promote the bonding of the bitumen with the concrete roof deck or masonry surface. This standard is intended to cover the minimum requirements for bitumen primer for use in waterproofing and damp-proofing of building.
TIKI PRIMER OB is applied to concrete and masonry surfaces and to be used with bitumen in damp-proofing and waterproofing below or above ground level.
The surface should be free from dust grease, rust and loose particles.
The primer shall conform to the requirements given below:
|1. Viscosity by standard tar viscometer, 4mm orifice, in sec at 25°C||4 to 24|
|2. Distillation fractions, percent by volume of the primer:
a) Upto 225°C Min.
b) Upto 360°C Max.
|3. Flash Point Pensky Martens closed type, Min||40°C|
|4. Water Content, percent. Max||0.2%|
|5. Test on residue from distillation upto 360°C
a) Ductility, 25°C, Min
b) Penetration at 25°C, 100gm, 5sec in 1/100cm
c) Matter soluble in Carbon disulfide or carbon tetrachloride
or trichloroethylene, percent by weight Min.
20 to 50
