Surfacine

The Surfacine Advantage

 
    Surfacine Medical Grade Disinfectant Antimicrobial Agent Compounded Into Bulk Polymer Silver Deposited On Surface

Mode of Application

  Molecularly designed surface treatment Floods surface Antimicrobial agent is compounded with polymer Metallic silver surface film by vacuum deposition, ion sputtering, etc.

Mode of Action

  Surface contact only, microbial surface contact exposes organism to antimicrobial agent Chemically compromises micro-organism depending upon nature of disinfectant Active agent diffuses to the surface where it may be leached away by contact with liquids, other surfaces, etc. Surface contact with micro-organisms, as well as significant slow leaching into solution

Bio Availability

  Very high for surface contact, none in solution High while immersed, none thereafter High on fresh surfaces, low on surfaces in contact with clean solutions High for surface contacts, moderate in bulk of solution

Duration of Activity

  Long term Short term. Active only while surface is wetted with agent and agent is not chemically exhausted Depending on compatibility of active agent with polymer. Short to medium term Long term

Reservoir Capacity

  High None Depending on compatibility of active agent with polymer. Low to high High

Leaching into Solution

  Less than 50 ppb, often below 10 ppb Depending on the disinfectant, often 5 to 10 ppm or higher Depending on solution contact time with surface. Often exceeds 100 ppm Greater than 5 ppm, depending on the contact solution

Time to Kill Micro-organisms

  Moderate Fast Slow to moderate depending on surface concentration Moderate

Spores Activity

  Low Moderate Low Low

Virus Activity

  Undetermined Depending on disinfectant Typically none None

Toxicity to Humans

  None High Depending on active agent Low to none

Sensitivity to Surface Fouling

  High Low Low Moderate

Vulnerability to Crevices

  Low High Low Low

Limitations

  Activity will be reduced with surface fouling Must be applied repeatedly, wetting all surfaces and crevices, and remaining undiluted Activity related to surface concentration and availability of leaching agent. Appropriate to polymeric materials Microorganism may either come into contact with surface or reside in a solution that has been in contact with the surface

Substrates

  Most Most (some surfaces may be damaged by disinfectants) Polymeric Most

Mechanical Robustness

  Can be engineered to meet requirements over wide range Not applicable Equivalent to properties of base material Low

Manufacturing Compatibility

  Flexible post-manufacturing process Not part of the device Changes material's manufacturing and mechanical properties Vacuum line-of-sight deposition

Cost of disinfection activity

  Low for long term protection High, assuming repeated applications Generally low, depending on agent High for long term protection
