1 product introduction
G-881 protective paint is a silicone modified conformal coating, can generate protective film in a variety of printed circuit board, prevent leakage and short. Transparent protective film which can prevent the erosion of acid, alkali, alcohol, moisture, and cold and heat shock resistant, ageing resistance, radiation resistance, salt fog resistance, ozone resistance, corrosion, vibration resistance, flexibility, adhesion, good performance. This product has better mildew, resistance to high temperature, heat will not drop.
2 scope of application
Waterproof and moistureproof, mouldproof, salt fog to improve the insulation strength. Isolation of wire and cable, insulation wire joint, screw contacts, switch box and air contact. For corona TV can prevent high-pressure components such as leakage caused. Also can be used to protect the map, chart, documents, drawings, manuscripts and other soft goods. To prevent the erosion of atmosphere on the VHF antenna, TV antenna, radio antenna. The protection of marine communications equipment, electronic equipment from salt fog corrosion.
3 characteristics and advantages
Moisture proof and salt fog. To prevent corrosion, prolong the service life of equipment. Protection of lasting effect. Protection for electrical appliances, equipment, spare parts and lasting. High temperature resistance. The construction method can use brush, spray, dip, spray method.
