Silicone Primer CL-26AB-16 
LSR &PPSU overmolding

CL-26AB-16, Silicone primer, is mainly applied for  bond LSR or HTV silicone with PPSU, PP. etc.which will result in a tight bond after molding process 

lsr ppsu overmolding

High Tear Strength 

The Silicone rubber is damaged when tearing from PPSU

LSR Silicone overmolding PPSU

Adhesion Strength is over 2Mpa, No bonding failure

ISO9001, SGS certified  

                                                                      No Bubbles 

                                                                                                         Making your silicone products 99% ok rates

                                                                                                         No primer traces after the silicone products is made

Labour costs saving

Easy processing, Can dip dry, No corrosion to PPSU

                                                                                      Stable Quality 

                                                                                                                                   3 Times standard tests 

                                                                                                                                   zero silicone falls aparts from substrates

1, Treat the substrates with blast sanding, polishing or wash with industrial alcohol.                                           

2, Mix completely the A and B with ratio 1:1 and apply the primer by dipping, brushing, spraying or silk screen printing method. 

3, Leave dry in room temp for 30 minutes or baking at 110-130℃ for 15-20mintes.                                                  

4, The primer treated substrates are processed within that day.                              

5, Foward the unvulcanized silicone rubber with primer-coated substrates in mouding process or hot air vulcanization.      

2, Please cap its cover after use to avoid volatilization. (store the used primer in separate way to lengthen the storage time)                        

3, The solvent is harmful, the workplace should be ventilated and fireproof and avoid long term inhalation and skin contact. 

4, The compatibility test is required for the silicone primer with substrates in mold curing process as the primer will result in bad cure 

when contacting with organic compounds like N, P, S, Sn, Pb, Hg, Sb, Bi as ionic compound.
