Automotive Glass & Body Sealants

Where these coatings are used

Direct glazing adhesives

Body seam sealers

Underbody seam protection

Industry Problems

  • Bead slump or loss of shape in vertical joints
  • Cracking under cyclic movement
  • UV-driven degradation of polymers causing chalking and adhesion loss
  • Colour mismatch or fading of black/grey sealants over time
  • Bead slump or loss of shape in vertical joints
  • Cracking under cyclic movement
  • UV-driven degradation of polymers causing chalking and adhesion loss
  • Colour mismatch or fading of black/grey sealants over time

Carbon black expectation

Higher jetness than standard construction sealants, but still with:

  • moderate structure
  • good UV absorption
 → balance between flow and body

Surface chemistry compatible with epoxy/PU – no interference with curing or adhesion promoters.

ISTAR solution positioning

ONYX GEMS®

for high-jetness automotive glass adhesives.

EMPIREX®

for seam sealers needing robust mechanical performance and colour stability.
