CRL 960806323 Tremco DyMonic FC White Polyurethane Sealant

CRL 960806323 Tremco DyMonic FC White Polyurethane Sealant

C.R. Laurence 960806323 White Tremco DyMonic FC Polyurethane Sealant is a high-performance, moisture-curing sealant designed for professionals seeking durability and reliability in their projects. This one-component sealant boasts a fast skin time of just one hour at 70°F (21°C), significantly reducing dirt pick-up, making it ideal for construction environments. With primerless adhesion on most common substrates, it simplifies application while ensuring a strong bond that withstands the test of time. DyMonic FC is perfect for sealing dynamic moving joints in precast concrete panels, curtainwall systems, and tilt-up panels, as well as for expansion and control joints around windows and doors. Its non-sag consistency allows for easy application with traditional caulking tools, enhancing user efficiency. The sealant meets stringent industry standards, including U.S. Federal Specification TT-S-00230C and ASTM C 920, ensuring it meets professional requirements. However, it is essential to apply DyMonic FC to clean, dry surfaces, as damp or contaminated substrates may require priming. Additionally, painting over the cured sealant is not recommended due to potential cracking. With a shelf life of 12 months and supplied in convenient 10.1 oz. cartridges, this sealant is a reliable choice for any glazing or construction professional.

White 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.
