Three, LED soft article lamp potting glue used method

1, before using the A and B component glue material fully stir well respectively.

2, A, B two components according to the above weight than take after said, mixing and stirring evenly, after vacuum deaeration water into clean electronic components, natural curing at room temperature.

The four, LED soft article lamp potting glue

1, this product curing speed has close relationship with environment temperature and humidity, the higher the temperature and humidity, operating time is short, fast curing speed; The user can according to the high or low temperature and humidity, appropriate adjustment of dosage of curing agent, can achieve the ideal curing speed.

More than 2, the quality of the product specifications for customers to use as a reference only, and can't guarantee a particular environment can achieve all of the data; The user before use should be according to the environmental temperature and humidity, confirmed by the test in the back.

3, after open barrels of material should be paid attention to clean, not use up stuff should tighten the cap.

Five, LED soft article lamp potting glue packaging, storage and transportation

1, this product USES A 20 kg plastic drum, component B component 2 kg bottled.

2, this product should be sealed storage in shady and cool place, prevent weathered, expiration period for 3 months.

3, this product according to the transport of dangerous goods.
