High Demand Item – Frequently Reordered by Contractors
Everkem EvoSeal MS (Gray) is a high-performance, single-component MS hybrid polymer sealant that delivers the flexibility and waterproofing of silicone with the paintability of acrylic — without the trade-off. Meeting ASTM C920 with ±25% joint movement, it stays flexible from -75°F to 220°F and bonds tenaciously to EPDM roofing, aluminum, Kynar-coated metals, PVC, vinyl, steel, glass, masonry, and concrete. Solvent-free, low-VOC (19 g/L), paintable, and applies in cold conditions down to 30°F — built for commercial glazing, EIFS, facade, roofing, and movement-joint work.
Applications
- Expansion and movement joints
- Commercial glazing, curtain wall, and facade
- EIFS and exterior insulation systems
- Window and door perimeter sealing
- EPDM, metal, and membrane roofing details
- Commercial and industrial construction and maintenance

How It Compares — EvoSeal MS vs. OSI Quad Max
If you've been buying OSI® QUAD® MAX, the Everkem EvoSeal MS is the same class of product — an advanced MS/SMP hybrid polymer sealant that's flexible, weatherproof, and paintable, meeting ASTM C920. The two are tuned for slightly different work: Quad Max leans toward siding color-matching and maximum movement, while EvoSeal leans toward commercial/industrial joints with a wider service-temperature range — and ships in the same order as your firestop and PVF supply.

Frequently Asked Questions
Is it paintable?
Yes — with latex paint after about 2 hours, or oil-based paint after 24+ hours. Unlike silicone, EvoSeal MS accepts paint.
How much joint movement does it handle?
±25% per ASTM C920. For joints needing greater movement, verify the design against the sealant rating.
What substrates does it bond to?
EPDM roofing, aluminum, Kynar-coated metals, PVC, vinyl, steel, glass, marble, brick, concrete, wood, and many plastics.
Can I apply it in cold weather?
Yes — it applies in conditions down to 30°F and stays flexible across a wide service range of -75°F to 220°F.
Is it solvent-free?
Yes — solvent-free, low-odor, and low-VOC at 19 g/L.
