SIGMAGUARD™ 260
RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES
Substrate conditions
• Steel; blast cleaned to a minimum of ISO-Sa2½
• Blasting profile 50 – 100 µm (2.0 – 4.0 mils)
• The substrate must be perfectly dry before and during application of SIGMAGUARD 260
Substrate temperature and application conditions
• Substrate temperature during application and curing should be above 5°C (41°F)
• Substrate temperature during application should be at least 3°C (5°F) above dew point
INSTRUCTIONS FOR USE
Mixing ratio by volume: base to hardener 87:13
• The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be
required to obtain application viscosity
• Adding too much thinner results in reduced sag resistance and slower cure
• Thinner should be added after mixing the components

SAFETY PRECAUTIONS
• For paint and recommended thinners see INFORMATION SHEETS 1430, 1431 and relevant Material Safety Data Sheets
• This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between
the wet paint and exposed skin or eyes
WORLDWIDE AVAILABILITY
It is always the aim of PPG Protective and Marine Coatings to supply the same product on a worldwide basis. However, slight
modification of the product is sometimes necessary to comply with local or national rules/circumstances. Under these
circumstances an alternative product data sheet is used.
