3 Operation Methods
1Main solvent and curing solvent mixed by 10:3:10 in measuring cup
2Add glue in a containers larger than the pieces.
3Pieces soak in the glue within 2-5 seconds.
4Taking out the dipped piece slowly and tilting,making surplurs glue flow .
5Puting pieces horizontal on the absorbent paper (small pieces) or a trestle (bulky), curing in 1 hour
6Checking the surface, if were not covered by glue,make it perfectly.
7Staying 24 hours and painting finished, packaging.
4 Operation Notes
1Before spraying PC boards or electronic ,the surface should be dealed with (to get rid of oil and dust) in order to make glue more efferctiveness.
2The materials include 2101A,2101B and 2101C components
3Brushing spraying,dip-coating can be chosed,diluted with 2101 C
4Mixed A : B = 10:3 and if required thinner brush or spraying ,using 2101 C.Mixing ratio A100 + B30 + 100 C
5If do the twice then should wait until the first cover dry.
6expiration date:12 months (stored in cool,dry places)

Three proofings paint

Three proofings paint is a kind of special paint,used in protecting PCB and other related equipments from the harm of environment Thereby enhancing their duration and ensuring the safety and reliability.

Three proofing paint used as PCB coating, forming a light and flexible flim only 25 -50 microns thick. It can protect circuits from chemical substances (for example : fuel, cooling, etc.), vibration, moisture, salt spray, humid and high temperature under which conditions PCB likely to be corroded, mold growth and short-circuit.   


Benefits:

Three proofing paint film can effectively isolate and protect circuits against chemicals, moisture and dirt erosion, thereby enhancing the reliability of circuit boards to increase their safety coefficient as well as its lifespan. Because Three proofing paint can prevent electricity
leakage, thus allowing a higher power and the more smaller PCB space. So the smaller components can meet the need. Both transparent and colored Three proofing paint can improve the appearance of circuit board, and the latter covered the layout and design of components can guarantee a higher degree of confidentiality


Typical use
At first Three proofing paint applies only to the high-tech field of printed circuit boards. Now consumers are increasingly concerned about the quality and reliability of the products .what’s more the electronic devices has been more widely used in daily life.Using Three proofing paint can improve product quality and consistently reduce the warranty-period repair costs. Typical uses include the following areas

Civilian and commercial uses

Three proofing paint can be used for household electronic circuits protection so that they can resist :

Water and detergent (such as : laundry machines and dishwashers)

High humidity (such as microwave ovens)

Chemical environment (such as : washer / dryer)

Office and the family of harmful substances (such as computers)

The adverse external environment (such as : Burglar Alarm Device)

Automobile industries

Three proofing paint used in Automobile industries will protect circuit from the following types of hazards, such as : gasoline vapors. salt spray / brake fluid and so on. Electronic systems applied in motor vehicles is growing rapidly. Therefore, using the Three proofing paint has become the basic requirement of electronic device to ensure long-term reliability. Three proofing paint applied to the following aspects :.

Machine enclosures (eg : Engine Management System)

Passenger vehicle (Add : Inside the computer control system)


Aerospace and aviation

Aerospace and aviation environment have strict requirements of the electronic equipment in terms of the rapid changes of pressure which have the impact on circuit performance. So it is a must to use the Three proofing paint widely. Three proofing paint can be applied to the following areas :

Pressure reducing: (eg: flight line control system).

Cabin (eg : air conditioning system)

Navigation

Both fresh water and salt water will cause harm to the electrical equipment shipping circuits. The use of Three proofing paint can protect the equipment on the surface effectively and for the underwater equipment, the use of resin to protect is a must also. Typical applications include: Navigation system

Radar Control System

Medical / industrial   

Medical / industrial using Three proofing paint to protect the equipment from the adverse external environment.It is used widely
including :

Tools - to prevent corrosion and easy to store.

Agricultural machinery – prevent pacemaker pollution from fertilizers and field wastes to ensure continuous stability
