Permahyd Application
Substrate preparation
When applying water-borne products, the substrate must always be prepared with great care using only
products recommended for water-borne coatings.
Metal substrates should preferably be cleaned with Permahyd® Silicone Removers 7085, or 7096.
Clean sanded surfacer areas and old finishes with Permahyd® Silicone Removers 7085, or 7096 (see Data
Sheet 770.2). Plastic surfaces must be carefully prepared in accordance with the System Data Sheet for
painting plastics (see Data Sheet 901.1) and cleaned once more with Permahyd® Silicone Removers 7085,
or 7096 before further recoating.
Masking
Use only waterproof masking tape and masking paper or plastic sheeting.
Spray guns/spray equipment
It is not advisable to use the same spray gun/spray equipment to alternately apply water-borne and
conventional products. The components of spray guns/spray equipment coming into contact with waterborne products in the course of application must be made of a corrosion-resistant material (stainless steel).
It is important to review the product TDS for proper spray gun set up prior to application.
Mixing containers
For mixing and adjusting the viscosity of water-borne products use only tins made of compatible plastic or
coated containers.
Material temperature
Since the viscosity and thus the application characteristics of water-borne products depend to a great extent
on the material temperature, water-borne products must be at least 65°F (18ºC) at the time of viscosity
adjustment / application.
•
Store at min. 65°F (18ºC) or allow corresponding warming time before viscosity djustment/application.
Minimum reaction temperature
When applying water-borne products, the minimum reaction temperature given in the Technical Data Sheet
must always be allowed for drying.
•
See respective Product Data Sheet.
Maximum mixing temperature
If the maximum mixing temperature of water-borne products is exceeded the pot life may be reduced by
such an extent that application is no longer possible.
•
See respective Product Data Sheet.
•
Store correctly.
•
Cool down before mixing if required.

Permahyd Application
Application
The application of water-borne products is influenced to a great extent by temperature and air humidity.
This may restrict the application or make it even impossible unless certain conditions are fulfilled.
Assuming that in an up-to-date paint shop an application temperature of at least 68°F (20ºC) is guaranteed,
particular measures are required only with regard to the air humidity if it is outside the application range.
Controllable Factors
Spray booth temperature
Mixing ratio
High Humidity
Increase Temperature
Permahyd- use less VE6000
Hi-TEC – increase amount of 6050
Spray gun size, set up
Air pressure
Spray gun distance
Gun speed during application
Reducer selection
Smaller nozzle
Increase
Increase distance to panel
Faster passes
Permahyd- use VE6000
Hi-TEC – use 6050
Low Humidity
Decrease Temperature
Permahyd- use more VE6000
Hi-TEC – decrease amount of
6051
Larger nozzle
Decrease
Decrease distance to panel
Slower passes
Permahyd- use VE6000 with 6002
Hi-TEC – use 6051 with an
addition of up to 10% VE6000
Intermediate and final flash-off times, recoating times
When applying water-borne products, the flash-off times between individual coats and final flash-off or
recoating times are adversely affected by low temperatures and high air humidity. The drying processes
between the individual coats and before further recoating can be accelerated by:
1.
Accelerated evacuation of moist air
• blow with air diffuser
• Use Speed Dry air jet system
• Increase air rate in the spray booth (Modern spray booths take account of this option.)
2.
Use of drying energy
• IR
• Combination booth
• Oven
Important Regulatory Information
•
•
For industrial use only by professional, trained painters. Not for sale to or use by the general
public. Before using, read and follow all label and MSDS precautions. If mixed with other
components, mixture will have hazards of all components. Do not sand, flame cut, braze or
weld dry coating without a NIOSH approved air purifying respirator with particulate filters or
appropriate ventilation, and gloves.
