Comparison SAR306 vs 999

Same reactivation Temperature: 60/70°C
Dry content similar on compared

samples 16,0% vs 15,7%
Open time similar 3’30’’ vs 4’
Viscosity very similar 50’ vs 45’
Better Initial Heat resistance at 70°C (1,5cm opening in 10’ vs 3cm)
Slightly better 24h Heat resistance at 85°C (9cm opening after 15’ vs 12cm)

Comparison SAR306 vs SAR06W

All measured features are quite similar, within the

method tolerance
SAR06W has a slightly longer open time
Solvent mix of SAR06W allow to accomplish Ukraine solvents limit
