Euclid Eucolastic 1NS Polyurethane Hybrid Sealant, White 10.1 oz Cartridge
Euclid Eucolastic 1NS is a single-component, non-sag, moisture-cured polyurethane hybrid sealant. It is formulated with a silane-terminated polyurethane polymer for dynamic joints. It is used on vertical and overhead control and expansion joints, including precast panels, EIFS, masonry, and window perimeters, above and below grade. The sealant stays bonded through temperature cyclic movement.
Key Features
- Single-component, non-sag polyurethane hybrid
- Silane-terminated polymer for dynamic joints
- Remains adhesively and cohesively bonded during temperature cyclic movement
- +/- 35% movement capability
- Paintable after full cure
- Typically bonds without primer on common substrates
Applications
- Concrete control and expansion joints.
- Precast concrete panels.
- EIFS and masonry.
- Window and door perimeters.
- Interior or exterior, above or below grade.

Frequently Asked Questions
What movement capability does Euclid Eucolastic 1NS have?
Typical laboratory movement capability is +/- 35% (ASTM C719). Euclid Eucolastic 1NS remains adhesively and cohesively bonded during temperature cyclic movement. Expect reasonable variation under field conditions.
Where is Euclid Eucolastic 1NS used?
Euclid Eucolastic 1NS is used on vertical and overhead dynamic joints: concrete control and expansion joints, precast panels, EIFS, masonry, and window and door perimeters. It is used interior or exterior, above or below grade.
What Shore A hardness does Euclid Eucolastic 1NS show?
Typical laboratory Shore A hardness is 25 (ASTM C661). Expect reasonable variation under field conditions.
What skin time does Euclid Eucolastic 1NS hold at 75 F?
A skin forms on the surface in about 1 hour at 75 F and 50% relative humidity. Cure rate is about 1/16 in per day. Time increases or decreases as temperature and humidity fluctuate.
How soon can Euclid Eucolastic 1NS be applied to concrete?
New concrete should be at least 28 days old. Joints must be clean, sound, and dry. Wet or damp joints cause bubbling.
What application temperature does Euclid Eucolastic 1NS need?
The substrate must be at least 40 F and rising, and below 150 F, at the time of application. Store Euclid Eucolastic 1NS at room temperature prior to application.
