When we develop our SLIP-COAT coatings for automotive weatherseals, there are two interfaces that need to be considered. OEMs are most concerned about the coating to mating surface interface that we call ‘the perceived value interface.’ This is where the coated weatherstrip meets either glass, painted metal, other coated seals, smooth and textured PU, leather…

GBIE SLIP-COAT coatings for automotive weatherstrips are known for their durability and superior adhesion to the substrate but how can we consistently achieve these qualities when there is such a wide range of different elastomer-based compounds used in weatherseal applications?  EPDM or TPE is not a single uniform material, there are thousands of compounds of…

Pretreatment before applying coating to automotive weatherseals can be very effective but it is not always needed. Some pretreatments can even reduce coating performance. Using pretreatments adds process complexity and cost: either capital cost for expensive plasma and corona systems, or material costs for primers. GBIE’s R&D lab always works with our customers to determine…
