Cafco® PSK 101 - Sealer & Keycoat
INTRODUCTION
CAFCO® PSK 101 is a single pack, multi purpose synthetic latex, water based emulsion for use as a sealer and keycoat as a component of the Cafco FENDOLITE® integrated fire protective coating system.
CAFCO® PSK 101 is suitable for on site or off site application to construction elements such as steel or concrete sections and metal decks.
Onshore oil and gas, petrochemical and power industries will benefit from the use of CAFCO® PSK 101.
| Properties and performance |
| Colour and finish |
Dark green (nearest to BS 4800: 1981, colour code 10 B 25). May be applied by spray, roller or brush |
| Typical thickness |
100-150 microns wet fillm thickness (WFT) Do not apply less than 100 microns 55-82 microns dry film thickness (DFT) |
| 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. May be recoated once previous coat is touch dry |
| Maximum over coating time |
2 months with either more CAFCO® PSK 101 or Cafco FENDOLITE® MII |
| Cure |
By air drying |
| Drying time |
Touch dry ½ to 1 hour at 20ºC and RH 50% Fully dry 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 will hinder cure significantly |
| Solids by weight |
55% |
| Weight |
1.25kg/litre |
ADVANTAGES
Strongly bonded coating system.
| Preparation |
| Typical substrates |
Unprimed or primed steel |
| Substrate preparation |
The substrate must be clean, dry and free from dust, loose millscale, loose rust, oil, visible moisture (including condensation) and any other condition preventing good adhesion
|
| Application |
| Initial steps |
Stir contents before use. Do not thin |
| Methods |
CAFCO® PSK 101 may be applied with an industrial type airless or air-assisted spray, or lambswool roller. It may also be applied with a brush in small (maximum 1m2) areas only |
| Limitations |
CAFCO® PSK 101 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
