Yes, when addition-reactive silicone gels come into contact with air (oxygen) during curing, the reaction will be inhibited, resulting in surface tack (known as "oxygen inhibition"). This is not an incomplete cure; it's normal. Surface tack can be eliminated by heating or using a nitrogen blanket. The interior and areas in contact with the substrate will be fully cured.
