Prime Rez 1200 Low Mod LV
Prime Rez 1200 Low Mod LV is a two-component, very-low-viscosity epoxy in a 2:1 Quick Mix cartridge, MPN 1250, for structural cracks in concrete, masonry, and stone that see shock or vibration. Viscosity is 70 to 90 centipoise at 73 F, so the resin injects or gravity-feeds hairline cracks. Compressive strength is 6,120 psi and tensile elongation is 35%. It conforms to ASTM C881 Type II and III, Grade 1, Class B and C.
Key Features
- Low-modulus epoxy is used on cracks that see shock or vibration
- Viscosity is 70 to 90 cP at 73 F
- Injects or gravity-feeds hairline cracks in concrete, masonry, and stone
- Compressive strength is 6,120 psi by ASTM D695
- Tensile elongation is 35% on the cured epoxy
Applications
- Hairline cracks in walls, floors, tanks, and decks that see vibration
- Gravity feed of tight cracks in horizontal slabs
- Bridges, retaining walls, and foundations with movement in the crack

Frequently Asked Questions
What cracks is Prime Rez 1200 Low Mod LV used on?
Structural hairline cracks in concrete, masonry, or stone that see shock or vibration. Typical work includes walls, floors, tanks, dams, parking decks, bridges, retaining walls, and foundations. The extra-thin resin injects or gravity-feeds those tight cracks.
What cartridge is Prime Rez 1200 Low Mod LV on this page?
A 2:1 Quick Mix cartridge, MPN 1250. Ratio is A:B 2:1 by volume. The datasheet also lists 3 gallon and 15 gallon units of the same chemistry.
What viscosity does Prime Rez 1200 Low Mod LV have?
70 to 90 centipoise at 73 F, the very-low range on the Prime Resins scale, so it enters tighter cracks than a high-modulus resin. Solids are 100% with no VOCs. Color is amber clear.
What strength does Prime Rez 1200 Low Mod LV reach?
Compressive strength is 6,120 psi (ASTM D695). Tensile is 4,230 psi with 35% elongation. Flexural is 2,760 psi. 14-day dry bond is 2,900 psi by ASTM C882. Shore D is 70.
What ASTM C881 class does Prime Rez 1200 Low Mod LV meet?
Type II and III, Grade 1, Class B and C. Do not use below 32 F, because ice in the concrete will block bond. Precondition to 70 F to 80 F.
What shelf life does Prime Rez 1200 Low Mod LV have?
1 year from manufacture in unopened containers stored dry between 40 F and 80 F. Do not freeze. Off-ratio material will not reach full strength.
