Two parts potting compound HM-312

Introduction                                                                                         

312 is two parts condensed type silicone potting compound, cured under room temperature, release alcohol, no corrosion to PC,PP,ABS,PVC and copper wire. Good adhesion for most electronic material(PP and PE exception)

Properties                                                                                       

1. Low viscosity, good flowability, suitable for mould pressing of complex electronic element

2. After cured, will be soft rubber-like material, excellent shock resistance

3. Heat resistance, moisture resistance, and excellent cold resistance, can extend service life of electronic elements.

Application                                                                                          

Used as potting adhesive for power module, electronic element deep layer, LED backlight,HID lamp,LED display,etc.

Parameter                                                                                       

We can adjust the viscosity,color,cured time according to your demand.

Shelf life                                                                            

·packaging： A：20kg B：2kg c:0.2kg/barrel

shelf life： should be stored in shady and cool place, under 30C. Our sealant has a usable life of 12 months when stay unopened.

Usage                                                                                   

1. Mixed A and B parts with ratio 10:1(weight or volume),after completely mixed, use vacuum

Pump to release the bubble, be careful ,the total amount should be less than 1/3 of the container, in case of any overflow. Also can release the bubble naturally by standing the sealant still for about 20~30 mins under 25C

2. Try to pour the sealant to the potting position as soon as possible avoid any air invade. Under room temperature, with 24H,this sealant can be cured and become elastomer,low temperature and mixed ratio will have great effect to curing time. 

Remark                                                                                      

1. Completely cured sealant is non-toxic, but do not directly contact with eyes or kids. Should keep ventilate when applying. We suggest that before applying, customer had better have a test to make sure our sealant can highly meet your demand.

2. Normally,the mixed ratio between A and B is 10:1,but we can adjust the mixed ratio to change the curing time. We don’t suggest using heating to accelerate the curing process,in case of  there will be some hole or bubble on surface, which have some bad effect on sealability.

3. Thickness of potting, better less than 50mm.Normally, thickness less than 20mm,the sealant can be release the bubble naturally. But if the potting position is very thick, better use vacuum pump, under 700mmHg,at least 5 mins to get rid of the bubble.

4. Before mixed, completely mixing each component separately.

5.If want matting ,could add the C(matting agent),normally the matting will appear 24~48h of potting. Under higher temperature, the matting will appear earlier, but do not make it over          50C
