Acrylic Conformal Coating

TL-204 is a colorless and transparent modified acrylic resin conformal coating. It features excellent environmental friendliness, free of heavy metals and aromatic solvents like xylene and ethylbenzene. Its low odor makes it very suitable for on-site operation. It can be applied by manual and mechanical brushing, dipping, flow coating, and spraying, with fast curing (5-10 minutes tack-free at 25℃). After curing, it forms a transparent protective film with good high and low-temperature resistance, excellent insulation, moisture-proof, anti-corrosion, salt spray resistance, and UL94 V-0 flame retardant properties. It has good adhesion (5B grade) to various circuit boards and is widely used for insulation and anti-corrosion protection of PCBs in home appliances, power supplies, instrumentation, and LED displays and lighting.Shelf life: 12 months

Operating Instructions

1.Clean the surface to be coated to remove impurities, oil stains, and other contaminants for the expected coating effect.
 
2.Suitable for manual and mechanical brushing, dipping, flow coating, and spraying.
3.Do not pour the dispensed adhesive back into the original package to prevent contamination. The workplace should be well ventilated or forced ventilated.
4.Recommended dry film thickness is 30-50 μm.
5.Reliability test conditions: After spraying, brushing, or dipping, leave the PCBA in a ventilated environment at room temperature for 168 hours, or bake at 50℃-60℃ for 4-6 hours, then leave for 24 hours before testing.

6.If accidentally contacted with skin, wash immediately with soap and water. If contacted with eyes, rinse with plenty of water first, then seek medical attention.
