TABLE A: FLUOROALKYL SILICONE INFORMATION
Procedures
In system I, a solventborne 2 part heat cured polyurethane
is modified with various fluoroalkyl silicones at 1% use level
and evaluated for appearance, slip, mar resistance, and stain
resistance.
TABLE B: FORMULATION OF SYSTEM I, A 2K SB/PU
FORMULATION
Preparation of System I: the fluoroalkyl silicone was added to
the A side at 1% of the total weight. Part A and B were mixed
in the ratio above. Five minutes later a 1 mL sample was drawn
down on an aluminum panel with a #10 wire wound rod. the
panel was heated to 110°C for 1 hour and then cooled/condi-tioned in ambient for two hours before testing.
In system II, a UV cured urethane acrylate formulation was modified
with various fluoroalkyl silicones (FAs) at 1% use level and evaluated.
TABLE C: FORMULATION SYSTEM II, A UV CURABLE
URETHANE ACRYLATE SYSTEM
Preparation of System II: 0.5 ml of the coating above is drawn
on a 4”X6.5” white Leneta Chart paper with a #5 wire wound
rod. the wet film was immediately cured in a UV box using a
15 watt UVP bench lamp with two long-wave tubes. the entire
panel was exposed to the UV tubes at a distance of 3” from the
tubes for one hour.
In system III, the epoxy acrylate coatings prepared were
based on adding the FAs additive at 1% level into the resin
manufacturer’s starting formulation.
TABLE D: FORMULATION OF UV CURABLE EPOXY
ACRYLATE SYSTEM
each sample is drawn down on a Leneta paper using a wire-wound rod #10 to create a 1 mil thickness coating. that film
was then cured for at least 1 hour in a 10 mW/cm2 UV box.
