Plastik 70 thinner 5L

German KONTAKT PLASTIK 70 SUPER special-grade acrylic insulating varnish with UV money is a fast-drying, colorless, and transparent insulating varnish which can provide a protective coating based on a new type of acrylic resin. This product is a low-viscosity varnish with good insulating properties. Dries to a colorless, transparent, elastic finish. It can adapt to the temperature environment from -40℃ to +125℃ temperature range. The dielectric strength exceeds 80KV/mm. The coating contains UV-sensitive materials, which can be inspected by ultraviolet light. It does not contain silicon and is insoluble in water.

Product features:

1) This product can guarantee good insulation performance in high-temperature and high-humidity environments.

2) Ultraviolet light can be used to check whether there are omissions during spraying.

3) This product does not contain silicon and is insoluble in water.

4) The completely dry PS 70 Super can be removed entirely by THINNER 70 when used for repair work (e.g., welding).

5) This product is suitable for use in electronic equipment in harsh environments (high humidity, high salt spray).

6) PS 70 Super can be used to repair circuit boards coated with KF 1280 ND paint.

7) PS 70 Super can be used in systems such as avionics, marine electronic materials, telecommunications, communication equipment, precision electronic materials, and automotive circuits.

Instructions:

1) For small areas, the easiest way is to use the PS 70 Super in a spray can. Please keep the spraying distance at 20-30cm. For printed circuit boards, we recommend using PCC, a special cleaner for circuit boards, to remove grease, dust, and flux residues on the circuit boards before using PS 70 Super. After using this product, please spray backward for 2-3 seconds until the air is wholly exhausted to avoid nozzle clogging and affecting the subsequent use.

2) Barreled PS 70 Super can be used for manual brushing or air compressor spraying for mass production and manufacturing. When spraying, the original manufacturer's recommended ratio of stock solution and thinner (THINNER 70) is 2:1. Experimenting with the appropriate equipment should determine the exact mixing ratio.

3) For immersion method coating, it is necessary to control the immersion time and removal speed. The faster the removal speed, the thicker the removal material will be. Therefore, the conductive parts must be masked in advance if the immersion method is used.

4) PS 70 Super contains butyl acetate solvent. Printed circuit board materials and electronic components are usually not corrupted by this solvent. However, compatibility tests must be done in advance when applied to plastic surfaces (such as shells). In addition, it is essential to test its Adaptability, whether the plastic is susceptible to stress cracking (e.g., polycarbonate).
