Look at a snap shot of major innovations introduced by CONVERGENT which has transformed the industry as we know it.
A patent for hardening / sealing concrete and masonry substrates to provide protection against moisture and salt intrusion. This includes various reactive lithium treatment technologies for enhancing surfaces and mitigating ASR.
This included the acquisition of intellectual property from FMC including a strategic supply agreement and trademarks. ADVAN then launches CONVERGENT CONCRETE TECHNOLOGIES, LLC to commercialize these technologies.
Introduction of the PENTRA brand a line of specialty products for distribution.Introduction of PENTRA®-SIL Lithium Silicate Densifier replacing sodium and/or potassium silicate densifiers. This creates a new standard in the flooring industry for hardening, densifying, and sealing concrete.
Introduction of Patented Pentra®-Sil (244+), an advanced Hardener, Densifier and Sealer that provides moisture, salt and effloresce protection.
Introduction of Pentra®-Guard (HP) ~ the first “GUARD,” a micro-film forming inorganic Hardener/Sealer Hybrid to provide enhanced wear, chemical resistance, and stain protection for industrial floors.
Introduction of Pentra®-Paint a patented lithium inorganic coating as a protective colored coating for industrial floors and line marking paint.
Introduction of Pentra®-Guard (EXT) the first “EXT” ~ an inorganic Hardener/Sealer Hybrid for exterior applications providing enhanced wear, chemical resistance, and stain protection for pavers and other masonry substrates.
Introduction of the First “at-time-of-placement” Densifier allowing a curing compound to be applied directly over the densifier application; now PENTRA®-Sil (NL/H)
Introduction of Nano-Lithium® (ADVAN’s engineered lithium polysilcate technology) into a family of specialized performance products that offer higher performance for specific applications. These formulated (NL) products offered a unique strength and unmatched performance compared to conventional treatments allowing for optimized applications faster drying, higher solids, and more complete reactions.
PENTRA®-SIL Voted #1 Brand on the market Introductory range of Lithium products
Pioneering of the maintenance market with “micro-film forming treatment” (alternative to mechanically grinding and polishing method) using inorganic hybrid treatment and high-speed burnishing with diamond impregnated pads – enhancing gloss, stain and wear resistance. This process changed the way floors are maintained as well as constructed today.Introduction of Pentra®-Sil (C&N) and Pentra®-Sil (AC) Surface Sweating Alkalinity Control Formula and Primer, to neutralize surfaces suffering from alkalinity problems.
Introduction of Pentra-Protective Coating an Industrial Protective Coating as a breathable industrial product.(currently Pentra-Clad)
Introduction of SiRE™ a next generation reactive lithium silicone by ADVAN/DOW-CORNING under the “Powered by Dow Corning” program.
Introduction of Pentra®-Sil HD+C a patent-pending membrane film forming hardener that meets ASTM C309.Introduction of PENTRA®-FINISH a patented “non-whitening, non-streaking” inorganic hybrid treatment (High-gloss or Low-gloss) for concrete, tile, terrazzo and stone applications.
Introduction of Pentra®-Shield an anti-scale resistance treatment for concrete providing freeze-thaw protection against moisture and corrosive deicing chemicals Introduction of Pentra®-Melt a novel non-corrosive, fast-acting lithium deicer that will not cause ASR as a technology licensee from
Introduction of TRANSIL™ for diamond grinding and shot blasting patent pending composition and system for enhancing concrete wear and abrasion resistance protecting surfaces from rutting, skid loss and other distress.
Pentra®-Pel (SI) is a dual component product—mixing Part A with Part B provides Advanced Micro-bonding Stain Protection for stone, masonry and concrete. Pentra®-Pel (SI)’s reactive, hydrophobic and water-repellant properties protect porous and absorbent surfaces prone to water-borne staining, efflorescence, dirt and grime build-up.
Pentra®-Cure (MH) cures, hardens and densifies in a single application after finishing, creating a protected surface during the construction phase from accidental spills and staining which can damage the substrate’s intended profile. This all-in-one treatment minimizes hairline cracking, dusting, spalling and other surface defects common to improperly cured concrete.
The COLORFAST™ SYSTEM is a complete line of quality products designed and engineered specifically for the architectural polished colored concrete. The complete system includes: Stain, Micro-Coating, Finish and Gloss, everything needed to install – from surface preparation, application and finishing to reparation, protectiion and maintainance.
Nano-Lithium is engineered lithium silicate with high lithium purity and quality.
Nano-Lithium reacts effectively with concrete to form calcium silicate hydrate. This creates a harder, denser surface that is abrasion and stain resistant.
Sodium and potassium react violently in concrete, creating uneven clumps of calcium throughout the surface layer. These clumps form weak, erratic bonds that result in a shorter life cycle. Nano-Lithium’s small molecule size allows it to penetrate deeply and evenly, creating stronger bonds, increasing durability, and extending the life of concrete.
Reactive Silicon Hybrid Polymer (SiRE™) chemistry is cross-linked with Nano-Lithium® technology. Unique lithium polymerization and reactivity creates the best performance available today.
This stable but highly reactive silicon/lithium compound offers flexibility when formulating product-specific applications. Products using SiRE technology don’t just coat concrete with a top layer of protection; they penetrate the surface and chemically react to fortify and protect from the inside, out.
Treated concrete has enhanced resistance to staining and abrasion. SiRE also facilitates water repellency and stain resistance.
Rapid Separation Technology is an engineered chemistry that divides into layers for maximum efficiency and performance in a single application.
The curing component migrates to the surface as a film-forming moisture barrier while the Nano-Lithium Silicate penetrates and reacts with the free-lime and cement, forming CSH.
RST provides true curing and hardening in one application. The film created meets ASTM C-309 specifications and can easily be removed compared to alternative film-forming cures. RST saves time, labor, and money.
Convergent Group take the term “partnership” with customers very seriously. This means providing adequate technical support and training, meeting specifications and deadlines, and always standing behind and ensuring the quality of our compounds.
