Moisture transmittance through concrete slab is a common problem that can cause severe issues for subsequent flooring systems, including concrete flooring and resilient flooring (tile, carpet, vinyl). Moisture in concrete can occur from a variety of sources: ground moisture that contacts the slab through either capillary action or as water vapor, high air humidity or drastic changes in relative humidity in its environment, and more.
Ancamine® 2800 is a cost-effective and environmentally friendly, a CTL certified curing agent for moisture vapor barrier (MVB) flooring applications. It has a good combination of a long pot-life that offers an easy handling and a fast cure speed that provides a fast return to service.
Ancamine® 2803 is a unique epoxy curing agent that can be formulated as a 1:1 mix ratio with a standard liquid epoxy resin without the need of a urethane modifier. It provides the hardness, adhesion, and durability of epoxies with a degree of flexibility common to polyurethane and cure speed common to polyrueas.
Ancamine® 2803 is recommended for use as a flexible membrane in various applications where it is important to protect a structure from damages due to repeated shift and movement, including parking and bridge deck, joint sealant, and crack repair. It also provides cured coatings with the flexibility and strength needed for heavy stress concrete flooring.
Today’s petrochemical market provides new challenges to coatings manufacturers. Changes in the location, type, methods of drilling are resulting in higher temperatures and pressures that new coatings must withstand. Additionally, as the composition of the crude changes, chemical resistance becomes ever more important.
Ancamine® 2791 curing agent provides a solution to today’s challenges. This new low viscosity epoxy curing agent is designed to be used with standard liquid epoxy resin (LER) for normal conditions and with Novolac/Bis-F resins for harsher conditions and perform equally well.
As the flooring industry continues to look for ways to reduce time on the job and to improve safety, we continue to innovate and bring new alternatives to the industry.
Anquamine® 725 is a waterborne curing agent optimized for use in concrete flooring systems. This curing agent offers everything formulators need to create successful and long-lasting flooring systems. Developed primarily for use with liquid epoxy resins, Anquamine® 725 is a short recoat time primer and can be used as a topcoat – enabling one curing agent for both coats.
The world of composites tends to be constrained by existing process technology and well-established product performance. Now, Ancamine® 2903 and 2904 curing agents are enabling composite technology to move forward by providing improved performance properties as well as improved processing costs.
Ancamine® 2903 provides longer potlife than conventional cycloaliphatic curing agents, excellent mechanical strength and high ILSS (interlaminar shear strength) for moisture or water exposed applications.
We are pleased to share the article, “Encouraging Innovation: Environmental Regulations Drive Epoxy Formulation”, that appeared in the April 2015 Journal of Protective Coatings and Linings by Marcelo Rufo.
In this article, Marcelo explains the different definitions of VOCs and presents novel epoxy curing agents to address the challenge of today’s VOC regulations without sacrificing performance.
In addition to the conventional approach to reducing VOC’s through the use of waterborne technologies, Air Products offers the following game-changing solutions that eliminate fugitive plasticizers to the market, as referenced in the article.
