PennCoat Installs Slip-Resistant Floors

Slip Resistant Floors by PennCoat

Slip Resistant Floors

Slippery floors are a constant problem in manufacturing work environments.  While a slip-resistant floor is safer for pedestrians and vehicles, especially in environments where liquids spill or accumulate, the downside is that highly slip-resistant floors are harder to clean. Scientists measure slipperiness with the coefficient of friction (COF), which is a scale ranging from 0.01 (the least friction) to 1.00 (or higher for rubber-coated floors). The ANSI minimum COF to be rated as “high slip resistance” is 0.43. Ramps are required to have a COF of 0.46.

PennCoat Installs Urethane Cement Floors

Urethane Cement

Urethane Cement

Urethane cement is a superior flooring top coat. It is stronger than epoxy, abrasion resistant, chemical resistant, and thermo-shock resistant. It is a preferred floor for pharmaceutical and food manufacturing facilities. Normally, urethane cement is applied over a concrete substrate, but it can also be applied to marine-grade plywood subflooring.

Components

The product is packaged in three pre-measured parts: a pail of resin, a pail of hardener and a bag of aggregate:

  • Resin: The water-based resin is a blend of polyester-ether polyol and glycol ester, with coloring oxides and carbon black. The resin is free of volatile organic compounds.
  • Hardener: The hardener is an aliphatic polyisocyanate consisting of hexamethylene diisocyanate (HDI), the homopolymer of HDI, and a pinch of methylenedicyclohexyl diisocyanate. The hardener gives the coating its abrasion and UV resistance.
  • Aggregate: The sand/cement aggregate is a dry mixture of Portland cement, quartz and calcium/magnesium hydroxide. The material’s dust can cause lung injury or cancer, so it’s important to take suitable precautions.

The Epic Showdown – Epoxy Coatings vs. Polyaspartic Coatings

Epoxy Coatings vs. Polyaspartic Coatings

Ever since the construction of the first concrete floor, humanity has searched for a way to protect and beautify the surface. Epoxy coatings have been around for some time and have been popular protectors of concrete floors Fairly new to the party, polyurea polyaspartic coatings have quickly become the darlings of those who want a fast dry time. Let’s examine each of these contenders and see how they stack up against each other.

Epoxy Coatings

Epoxies are resin polymers composed of epoxide units, which are cyclic three-atom ether rings containing an oxygen atom and two carbon side-groups. The triangular units are electronically strained and are therefore quite reactive. Normally, epoxy resin is formed by reacting bisphenol A and epichlorohydrin, but variants popular for concrete floor applications include novolac and aliphatic epoxy resins. A typical application consists of an epoxy primer, a color base coat and two layers of polyurethane.

PennCoat – Hi-Temp Industrial Painting

Hi-Temp Industrial Painting

High-Temperature Coatings for Industrial Painting Contractors

We sometimes take on jobs requiring us to apply coatings that can withstand extreme temperatures. One such product, Hi-Temp 1027, is a paint/primer that can resist dry temperatures up to 1,400° F and protect “cryogenic equipment in continuous or cyclic operation from minus 300° F to 1000° F.” The coating can also:

  • Prevent corrosion when applied under insulation
  • Prevent stress cracking from corrosion
  • Adhere to rusted metals
  • Act as a low-vapor, high-build primer

Physical and Chemical Characteristics

Hi-Temp 1027 is an inert multipolymeric matrix consisting of a blend of aromatic hydrocarbons, solvents (xylene, naphthalene, ethylbenzene, dimethyl carbonate) and ground mica — about 7 to 13 percent by weight. The mica provides a number of benefits, including:
