CRL 960805323 Tremco DyMonic FC Limestone Polyurethane Sealant

CRL 960805323 Tremco DyMonic FC Limestone Polyurethane Sealant

C.R. Laurence 960805323 Limestone Tremco DyMonic FC Polyurethane Sealant offers unparalleled performance for demanding sealing applications. This fast skinning, one-component, moisture-curing polyurethane sealant is designed to provide a smooth, consistent finish once cured. With a rapid skin time of just one hour at 70°F (21°C), it minimizes dirt pick-up, making it ideal for various construction environments. DyMonic FC excels in its primerless adhesion on most common substrates, simplifying the application process. It is supplied in a non-sag consistency that guns easily with standard caulking tools, allowing for efficient and effective sealing of dynamic joints in precast concrete panels, curtain walls, and tilt-up panels. This sealant is particularly effective for expansion and control joints, as well as perimeter caulking of windows and doors. Meeting stringent industry standards, including ASTM C 920 and U.S. Federal Specification TT-S-00230C, DyMonic FC is engineered for durability and weather resistance. Its high strength and low modulus ensure that it can withstand moisture, shear, and deflection movement over time. However, it is essential to apply it to clean, dry surfaces and avoid using paint over the cured sealant to prevent cracking. With a 12-month shelf life, it's a reliable choice for all your sealing needs.

Limestone Tremco DyMonic FC Polyurethane Sealant

• Fast Skin Time, Less Dirt Pick Up
• Primerless Adhesion on Most Common Construction Substrates
• Regular DyMonic® Available in Sausage Packs

CRL Tremco® DyMonic® FC is a fast skinning, high performance, low modulus, one-component, moisture curing, polyurethane sealant. DyMonic® FC features a smooth, consistent surface when cured. It requires no priming when used on most common substrates, provided surfaces are dry, clean, and free from contaminants. It is supplied in a non-sag consistency which will gun easily with conventional caulking equipment. Because it skins in only one hour at 70°F (21°C) there is less dirt pick up compared to other polyurethane sealants. Regular DyMonic® typical skin time is 16 hours at 70°F (21°C).


Basic Uses
DyMonic® FC can be used to seal dynamic moving joints in precast concrete panels, curtainwall, and tilt-up panels. Also for expansion and control joints, perimeter caulking of windows and doors, bedding of mullions, frames, and panels. It develops a strong adhesive bond that will not deteriorate, and exhibits excellent weather resistance. Its balance of properties (high strength, low modulus, high recovery) makes it able to withstand moisture, shear, and deflection movement. Dymonic® FC exhibits a tenacious adhesion which will not diminish over product life.

Technical Data
Meets U.S. Federal Specification TT-S-00230C, Type II, Class A; Canadian standard CAN/CGSB-19.13-M87; and ASTM C 920, Type S, Grade NS, Class 50 (DyMonic® FC) Class 25 (DyMonic®), Use NT, M, A and O.

Limitations
Do not apply to damp or contaminated surfaces. Some substrates may require priming, such as certain high performance paints and architectural finishes. Painting over DyMonic is not a recommended practice since paint may crack and peel when joint movement occurs. Check cartridge label and Specification Data Sheet for additional limitations.
