Frequently asked questions about DOWSIL™ silicone sealant
01. What methods are commonly used to increase the adhesion of the DOWSIL™ Silicone Sealant?
Four common and useful methods to increase product adhesion include:
1/ Clean the application surface with a suitable solvent.
2/ Use primer.
3/ Change the surface energy.
4/ Grind the construction surface.
For more details on these methods, please contact Quoc Huy Anh's team.
02. Can the DOWSIL™ Silicone Sealant be used underwater?
Quoc Huy Anh does not recommend using DOWSIL™ Silicone Sealant on surfaces that are frequently flooded.
03. Can DOWSIL™ primer (auxiliary product) be used in place of surface cleaning?
No, the application surface is required to be properly cleaned in all cases, whether or not a primer is used.
04. Can the DOWSIL™ Silicone Sealant be diluted for spraying or soaking?
As a rule of thumb, you can dilute DOWSIL™ products with naphtha liquid DOWSIL™ OS, DOWSIL™ 236 Dispersion and XIAMETER CTG-1890 Protective Coating.
05. How long can DOWSIL™ Silicone Sealant last in outdoor conditions? Can they become brittle and break apart?
DOWSIL™ Silicone Sealant products will maintain their performance properties (stiffness, duration, elasticity) if the product is properly applied according to the solutions of Quoc Huy Anh Corp's technicians.
06. How should primer be used?
DOWSIL™ offers different types of specialized primers for each surface. When applying, you should apply a single thin layer to maximize the adhesion of the sealant and wait 30 minutes. If white spots appear on the surface, use a clean cloth to wipe them away. After 60 - 90 minutes, the paint will be completely dry and you can pump the sealant onto the primed surface.
07. Why does the primer appear white spots? Is this good?
When the primer is exposed to the outside environment, some chemical reactions can occur, leading to the appearance of white spots. You need to use a clean cloth to remove them to keep the paint in the best condition. Remember to close the can and store it in a cool place to avoid affecting the quality.
