Frequently Asked Questions
What is the difference between the 422B-1L can and the 422B-340G aerosol?
Both contain the same 422B silicone modified conformal coating formula. The 1L can is designed for brush, spray gun, or dip coating in medium-to-high volume production environments. The 340G aerosol is better suited for low-to-medium volume applications and rework where a spray gun is not available.
What is the difference between MG Chemicals 422B silicone and 419D acrylic conformal coating?
The 422B silicone modified coating offers superior moisture resistance, wider operating temperature range, and better flexibility than the 419D acrylic. However, silicone coatings are harder to remove for rework. Choose 422B for harsh environments; choose 419D for applications where reworkability is a priority.
Can MG Chemicals 422B-1L be thinned for spray application?
Yes. The 422B can be thinned with compatible solvents for spray gun application. Consult the MG Chemicals 422B technical datasheet for recommended thinning ratios and compatible solvents.
Is MG Chemicals 422B UV fluorescent?
Yes. The 422B contains UV fluorescent additives for inspection of coating coverage under a UV/blacklight lamp after application.
Is MG Chemicals 422B RoHS compliant?
Yes. MG Chemicals 422B is RoHS compliant. Verify with the current MG Chemicals safety data sheet and technical datasheet for the most up-to-date compliance information.
