Material Description
CAFCO® SC125 is a single pack, ready to use, synthetic
latex, water based emulsion for use as an elastomeric sealer. It is designed for application to primed steel.
CAFCO® SC125 forms part of the Cafco
MANDOLITE®
CP2 passive fire protection systems.
Building types that will benefit from the use of CAFCO® SC125, include
a wide range of educational, leisure and entertainment centres, commercial and industrial projects.
Advantages
|
Suitable as a sealer over alkali sensitive primers that have been applied to internal steel or concrete substrates
where flexing or distortion (within normal design codes) may occur. |
|
Will accommodate such movement and minimise the risk of the debonding or consequent cracking of
Cafco MANDOLITE® CP2. |

Typical Mechanical Properties
| Properties and
performance |
|
|
Colour and finish |
Yellow with a slight sheen (nearest to BS4800: 1981, colour code 06 E 50). May be applied by spray, roller or
brush. |
|
Typical thickness |
55-82 microns dry film thickness (DFT) from 100-150 microns wet fillm thickness (WFT).
Do not apply less
than 100 microns (WFT).
|
|
Practical coverage |
Dependent on surface texture, substrate porosity, application method and technique. |
|
Theoretical coverage |
8m²/litre at 125 microns (WFT) |
|
Number of coats |
One or more as required dependent on application technique. Additional coats may be applied once the previous
coat is touch dry. |
|
Over coating interval |
Touch dry ½ to 1 hour at 20ºC and RH 50% |
|
Maximum over coating time |
2 months with either additional coats of CAFCO® SC125, Cafco
MANDOLITE® CP2. |
|
Cure |
By air drying |
|
Drying time |
2 to 6 hours at 20ºC and RH 50%. The drying time will vary with ambient conditions, but high
humidity, low
temperature and low air change can extend cure time significantly. |
|
Solids by weight |
55% |
|
Density |
1.25 |
Please consult nearest Promat office for specific details relevant to local conditions.
|
|
| Typical substrates |
Primed steel and concrete |
| Substrate preparation |
The substrate shall be clean, dry and free from visible moisture (including condensation), dust, loose mill
scale, loose rust, oil and any other condition preventing good adhesion. |
|
|
| Initial steps |
Stir contents before use. Do not thin. |
| Methods |
CAFCO® SC125 may be applied with an industrial
type airless or air-assisted spray, or lambs wool roller. It may also be applied with a wide, soft nylon brush
in small (maximum 1m2) areas only. |
| Limitations |
CAFCO® SC125 may be applied when the substrate
and air temperatures are at least 2ºC and rising. Maximum air and substrate temperature is 45ºC.
Substrate temperature should be at least 2ºC above dew point temperature.
Protect from rain, hail etc. until dry. |
|
|
|
Packaging |
20 litre plastic drums. |
|
Storage |
Protect from frost, excessive heat (above 45ºC) and strong radiant sunlight. |
|
Shelf life |
Maximum 6 months. |
|
Environmental |
Do not discharge into drains, watercourses or soil. |
