Dymonic® 100

High-Performance, High-Movement Single-Component, Polyurethane Sealant

Dymonic® 100 is a high-performance, high-movement, single-component, medium-modulus, low-VOC, UV-stable, non-sag polyurethane sealant.

Basic Uses
  • Dymonic 100 is a durable, flexible sealant that offers excellent performance in moving joints and exhibits tenacious adhesion once fully cured.
  • Typical applications for Dymonic 100 include expansion and control joints, precast concrete panel joints, perimeter caulking (windows, doors, and panels), aluminum, masonry and vinyl siding.
  • Dymonic 100 is also an excellent choice as a fluid applied flashing material in rough opening perimeters for fenestration/window, door and curtain wall applications.

Product Details, Safety, and Installation
  • How damp can the substrate be prior to sealant application?

    Concrete should not be wet to touch; a quick method to test substrate for surface dampness is to apply tape (duct or masking preferred). If the tape adheres to the substrate, the surface is dry enough to apply sealant. If there is no adhesion between the tape and the substrate, repeat the test in 30-minute increments. The concrete can be damp during application, but do not apply sealant where there is standing water in or close to the joints.

    Please note that a clean and sound substrate is always required when applying any sealant.

  • When is it acceptable to apply Dymonic 100 to green concrete?

    Dymonic 100 can be applied to green concrete 24 hours after the forms have been removed. All concrete sealers or curing agents need to be removed by grinding before applying sealant.

  • What is the minimum batch size for a custom color order?

    Increments of 20 cases. Lead time, upcharge and minimum order quantities on special colors are listed on current customer policy documents.

  • What does the “100” stand for?

    Dymonic 100 has been tested and confirmed by ATI to have +100% extension and -50% compressions per a modified ASTM C719 test.

  • Are product samples available?

    All standard colors in cartridges will be available for sampling.
