Construction Sealants & Joints

Where these coatings are used

Building façades and glazing joints

Expansion joints in concrete and floors

Window and door perimeter sealing

Weather-sealants in infrastructure projects

Common chemistries

Polyurethane, polysulfide, silicone and MS polymer sealants.

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

Carbon black expectation

Relatively coarse, low-colour furnace or lamp blacks →
  • easy dispersion in viscous sealant bases
  • controlled, non-sticky rheology
High structure → elastic reinforcement and excellent thixotropy
Strong absorption in UV region → acts as UV shield for underlying polymer

Technical expectations

Fast wetting in acrylic / styrene-acrylic emulsions

Stability in tinting pastes and machine dispensers

Low foam tendency and good brush/roller application behaviour

ISTAR solution positioning

PLASTEXA®

ow-colour, rheology-friendly blacks for general construction sealants

EMPIREX®

for darker, premium façade sealants requiring stronger UV protection and better crack resistance.
