Any surface to be touched up or recoated should be protected. When the
recoat material is applied, the surface must be dry and free of all dirt, dust,
debris, oil, grease and other contamination.
INSPECTION
Degree of surface preparation shall conform to appropriate specifications as
outlined in SURFACE PREPARATION section. Film thickness of each coat
and total dry film thickness of the coating system shall be determined with a
non-destructive magnetic gauge properly calibrated.
RECOMMENDATIONS
Apply only on a clean, sound, properly prepared substrate.
Minimum ambient or substrate temperature is 50°F/10°C, at the time
of application. Optimal temperature is 75°F/24°C.
Maximum ambient or substrate temperature is 100°F/38°C.
Relative humidity should be between 0-90%.
Substrate temperature should be 5°F/3°C above the dew point.
Application and curing times are dependent upon ambient conditions.
Consult Carboline’s Technical Service Department if conditions are
not within recommended guidelines.
PRECAUTIONS
PLASITE Thinner #71 is recommended for clean up of the PLASITE 4550
material.
Before handling and application of this material consult the MSDS sheets.
As with any product, those handling PLASITE 4550 materials should
employ proper safety practice. Hypersensitive persons should wear
protective clothing, gloves, and use protective cream on any exposed
areas.
When PLASITE 4550 is used as a tank lining or in an enclosed area
circulation should be used during and after the installation. Circulation can
be discontinued once the material has cured. The ventilation equipment
should be capable of preventing the solvent concentration from reaching
the lower explosion level for the solvents used. The applicator should
monitor the exposure levels or use MSHA/NIOSH approved air respirators.
NOTES
Material Safety Data Sheets on PLASITE 4550 are available upon
request.
Specific information regarding the chemical resistance of PLASITE
4550 can be found by contacting Carboline’s Technical Service
Department.
A staff of technical service engineers is available to assist with product
application, or to answer questions related to Carboline products.
Requests for technical literature or service can be made through local
sales representatives and offices worldwide.
