Spraying
Bulk
SRC
needs to be thinned with
SRC Thinners (DCT)
before spraying. The optimum viscosity to give
coating quality and thickness depends on the spray equipment and conditions but a starting point could be 2
parts coating to 1 part thinners. If bulk coating material has been agitated, allow to stand until air bubbles
have dispersed. The nozzle of the spray gun requires to be selected to give an even spray to suit the
viscosity of the coating material.
SRC
is suitable both for use in manual spray guns and computer controlled airless spray equipment that
only coats the required areas of the PCB, eliminating the need for masking.
To ensure penetration of the coating beneath the components and in confined spaces, spray the assembly
from all directions to give an even coating.
After spraying, the boards should be placed in an air-circulating drying cabinet and left to dry for 2 hours at
room temperature prior to any heat curing.
Brushing
Ensure that the coating material has been agitated thoroughly and has been allowed to settle for at least 2
hours. The coating should be kept at ambient temperature. Gently apply the coating with a good quality
brush so as not to leave brush marks and so that the components and wiring are not disturbed.
Drying Times and Curing Conditions
SRC
will dry in air within 4 to 12 hours at room temperature. This cure time can be reduced by the use of
moderate heat. The coating should be tack free within 20 minutes. Any heat cure must be started after the
coating has become tack free.
