VINYZENE SB-27 is an antimicrobial solution of
Dichloro-2-n-octyl-4-isothiazolin-3-one in Polyvinyl chloride
polymer carrier. VINYZENE SB-27 additive is an effective
anti-bacterial & anti-fungi for use in Vinyl, polyurethane and
other polymeric compositions requiring antimicrobial protection,
providing long term preservation against bacterial/fungal attack
and will help prevent surface growth, permanent staining,
embrittlement and premature product failure.
VINYZENE™ SB-27, US EPA Approval: No. 2829-140
Normally antimicrobial material is applied to plastic in liquid
solvent (like VINYZENE BP-505) or in powder carrier. While using
antimicrobial in powder might cause dust hazard to human and
equipment, antimicrobial in liquid solvent might cause danger to
human skin and eyes.
VINYZENE SB-27 is provided in small pellet and will not cause dust
or irritation hazard to human skin and eyes. No special measure is
required for handling.
VINYZENE SB-27 is compatible with most of the resin and easily
mixed with resin in any stage of the process. SB-27 will not change
color or reduce the physical/chemical property of final product.
Just mix like pellet color master batch during intrusion.
The product with VINYZENE SB-27 properly applied should be
prevented from attack of bacterial and microorganism, even under
exposure to high temperature and atrocious weather for long term.

RECOMMENDED USE LEVELS
In general, VINYZENE SB-27 prevents growth of bacterial and
microorganism at a low dosage. The dosage should be determined by
sensitivity of final product to bacterial & microorganism,
requirement to antimicrobial effect, the usage purpose of final
product, outdoor condition. Following is a recommended dosage rate
basing on a result of laboratory and actual working circumstance of
Indoor usage: for PVC floor, wall paper, pad, automotive interior parts, parts
inside refrigerator, bath curtain – 1.0% VINYZENE SB-27
Outdoor usage: for automotive exterior parts, raincoat, rain canopy, water
drainage, pad for swimming pool, decoration for ships – 1.2%
VINYZENE SB-27 (12kg/1000kg mixture).
The total resistance ability of plastic to atmospheric exposure
might influence the activity of bacterial and microorganism exposed
to atrocious weather. Rohm and Haas provide extensive
microbiological, chemical and physical testing in order to assist
the manufacturer in determining the optimum level of antimicrobial
agent required for each compound.
