What’s the Difference?
Over the years, we’ve heard all sorts of questions about our silicone roof coatings. With a large product line, we understand that some of the subtle differences between our silicone can get confusing. Of all the questions we’ve been asked, however, the one that has been surfacing a lot lately is, “What’s the difference between HS 3201 and HS 3201 – High Build”? They’re both high solids, they’re both in our 3200 series, and even the buckets look almost identical. So where does the difference lie? This article will answer this question once and for all!
High Solids
- Can be spray-applied or roll-applied
- White, tan, light gray, and dark gray in stock
- Custom colors available upon request
- Available in 5-gallon buckets or 55-gallon drums
- Specific gravity at 25°C – 1.24 (weight per gallon)
- Tensile strength of 247 (strength of the silicone)
- Elongation strength of 237 (how far it can stretch before tearing)
High Solids High Build
- Can only be roll-applied
- White in stock
- Custom colors available upon request
- Available only in 5-gallon buckets
- Specific gravity at 25°C – 1.26 (weight per gallon)
- Tensile strength of 350 (strength of the silicone)
- Elongation strength of 174 (how far it can stretch before tearing)
So Which is Better?
Depends on the job. If you’re spraying your silicone, HS 3201 is definitely the one for you. HS 3201 also has more colors available on short notice and can be shipped in 55-gallon drums for larger jobs. If you’re applying your silicone with a roller, you may like HS 3201 – HB better. HB has high solids content, can be applied thicker per coat, and has a higher tensile strength. Due to this, for smaller or rolling jobs, HB could be a better option.
At the end of the day, both silicones are a great for nearly any roof type. The best thing you can do to figure out which silicone is right for your specific job is contact your regional manager. You can find your Regional Manager here!
