Product Description
Epoxy glue for metal has confidential role
Thermal conductive epoxy potting gum is a room temperature/heating curing epoxy resin glue.
This epoxy glue is used for design, protection of the potting need high strength or confidential electronic products.
Epoxy glue Thermal conductive epoxy potting glue without heating can cure. 5: 1 (weight ratio) completely mixed part A and part B, form protection in a period of curing time.
After curing glue has the following characteristics:
Against moisture, dirt and other atmospheric composition
High strength
Has confidential role
Solvents, no cure by-products
Have stable mechanical and electrical properties between -45° C-120° C
Operation time is a quantity of cement with 100 g.
A, B two components in proportion to remove mixing ratio, mixing, vacuum suction bubble in operation period, remove the potting products to casting, such as potting product is too big, suggest points potting, then according to The Times curing(80º C/90min or 25º C/10hr)
Operation caution:
Agent A place for a long time, maybe produce precipitation, mix part A and B access should be paid attention to save after sealing.
Mixing should pay attention to the same direction, otherwise, it will stir with too much bubble; Borders and the bottom of the container sizing material should also stir well, can appear otherwise stir caused by uneven local not curing phenomenon.
Casting the product vacuum pumping, remove again bubble can improve after curing products comprehensive performance.
Temperature is too low will lead to curing speed partial slow, heat cure advice; Potting thickness more than 2 cm above 80 º C not directly in the curing, lest cause explosive together.
This glue curing exothermic reaction, match the process as the quantity of cement can affect the operation, so the length of time with 100 g resin content of operation time is only a reference time.
Packing:
Agent A: 25 kg/drum; Agent B: 10kg/drum
Storage and transportation:
Part A and part B need to avoid light, heat, save after sealed. (Can be used as the non-dangerous goods transport and storage)
Shelf life Agent A: 1 year, Agent B: 6 months(25º C).
