Product Description
Product Description
This product is a low viscosity neutral polymer composite material, single-component, easy to spray, dip coating and brush coating. It has good resistance to high and low temperatures; after curing into a transparent protective film, it has superior insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, corona-resistant and other properties. Widely used in electronic components surface coating protection.
QLD590I Organic Silicon Triple Anti Varnish
Deoxidising silica gel, used for coating protection of LED electronic components, is not suitable for copper and PC materials.
QLD590K Acrylic Triple Defence Paint
Modified acrylic, free of silicone, ketone, phenol and other materials, blue colour under UV light, easy to detect.
QLD590P polyurethane triple-proof paint
Modified polyurethane, free of silicone, ketone and phenol, blue colour under UV light, easy to detect.

Operation process
1. Load the glue into the dipping bucket for dip coating, the circuit board or components should not be immersed too fast to avoid air bubbles.
2. When spraying, fill the spray bottle with adhesive solution and spray. Use thinner to clean the spray bottle after spraying.
3. If the viscosity of the glue is thick, diluent can be used to dilute. When a large amount of glue viscosity is low, the thickness of the coating is thin; on the contrary, the viscosity of the glue is high, the thickness of the coating thick. The amount of thinner is recommended to be 20~40%.
Notes
1. Unused glue should be sealed and stored. When used again, if there is crust on the seal or surface, remove it, which will not affect the normal use.
2. The construction site should be well-ventilated.
3. Cool and dry place sealed storage for 6 months. After the expiry of the test, it can still be used.
