Pentra®-Sil (HD+C)

Hardener, Densifier and Cure


Pentra®-Sil (HD+C) is a hardener, densifier and curing compound engineered with Responsive Separation Technologyô (RST). This combination creates a membrane barrier on the surface -Liquid Film Forming Curing Compound- preventing water from evaporating while allowing the Nano-Lithiumô component to penetrate and react with the free-lime and unhydrated cement particles. This novel layering process improves both curing and hardening characteristics, creating a tougher, long-term, abrasion-resistant surface IN ONE APPLICATION.

Pentra®-Sil (HD+C) is a water-based, clear, dissipating membraneforming curing compound, hardener and densifier. This single component application forms a tougher, abrasion resistant surface compared to traditional methods requiring post-densification (28 days later). Excellent for commercial and industrial concrete floors that need long-term protection against heavy wear and abuse, moisture, dirt and grime buildup. This earth friendly / bio based compound contains no solvents and has a VOC content<100g/L making it compliant in Europe.

  • The performance of a true cure, hardener and densifier in a single application.
  • Cost-effective, all-in-one curing and hardening
  • Easy auto-scrub final cleanup
  • This earth friendly / bio based compound contains no solvents
  • VOC content<100g/L -compliant in all regions of the United States.

We’ve Redefined Curing

A true cure takes the high road, meeting the current ASTM C-309 specifications for maximum performance results. Pentra-Cure (MH) combines Nano-Lithium densifying technology and curing into one.

It’s the cure, reinvented.

Innovation at its Best

For years, curing and densifying have required multiple applications by different contractors. Using Rapid Separation Technology (RST), Convergent has merged these processes into a single one-step product that does both.

Responsive Separation Technology (RST)

The emulsion naturally returns to separate layers on the slab. The curing compound 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.
