The ONE-and-ONLY Chinking You Need to Know - PERMA-CHINK!

Introducing Advanced Formula - BLISTER-PROOF and NO-SLUMP!

Through a molecular technology breakthrough, Perma-Chink Systems created a blister-proof, no-slump chinking that provides superior adhesion and elongation, is heat and age resistant and yet is highly workable for ease of application.

Perma-Chink was the first synthetic chinking produced in 1981. There have been many significant changes made in formulations to improve the adhesion, flexibility, and longevity.

For the past two years Perma-Chink Systems intensively researched and tested adhesion, elongation, workability, heat resistance and process stability of Perma-Chink chinking. These extensive studies concluded successfully when our chemists were able to incorporate molecular breakthrough technology to create a blister proof, no-slump chinking that provides superior adhesion, is heat and age resistant and yet is highly workable for ease of application.

Today’s Perma-Chink offers excellent qualities in all areas to meet the needs of the industry.

  • Highly Elastic – Stretches to Accommodate Log Movement
  • Great Viscosity–Tools Easy in Low and High Temperatures
  • Will not Slump – Applied Film Stability
  • Blister Proof – Excellent Heat Resistance
  • Great Adhesion – Resists Separation from Logs
  • Low VOC – Environmentally Friendly
  • Freeze/Thaw Stable
  • Beautiful Color Palette to Match Shades and Hues of Today’s Finishes


The RHEOLOGY of Perma-Chink

Theoretical aspects of rheology are the relation of the flow/ deformation behavior of material and its internal structure.

The rheology additives in Perma-Chink help ensure that the polymer properties meet specifications for the end use (texture, product film properties) and product quality.

Rheological properties of Perma-Chink:

  • Greatly improved low shear (as in standing after application) results in high viscosity to prevent slumping
  • High shear (as in pumping ) decreases viscosity to make the product easier to apply and tool
